TESTNG - QUICK GUIDE
http://www.tutorialspoint.com/testng/testng_quick_guide.htm
Copyright © tutorialspoint.com
Testing is the process of checking the functionality of the application whether it is working as per
requirements and to ensure that at developer level, unit testing comes into picture. Unit testing is
the testing of single entity classormethod. Unit testing is very essential to every software company to
give a quality product to their customers.
JUnit has driven developers to understand the usefulness of tests, especially of unit tests when
compared to any other testing framework. Leveraging a rather simple, pragmatic, and strict
architecture, JUnit has been able to "infect" great number of developers. Features of JUnit can be
seen in Junit Features.
Some of the short comings of JUnit are:
Initially designed to enable unit testing only, now used for all kinds of testing.
Cannot do dependency testing.
Poor configuration control setUp/tearDown.
Intrusive forcesyoutoextendclassesandnameyourmethodsacertainway.
Static programming model forcesyoutorecompileunnecessarily.
The management of different suites of tests in complex projects can be very tricky..
What is TestNG?
Definition of TestNG as per its documentation is:
TestNG is a testing framework inspired from JUnit and NUnit but introducing some new
functionalities that make it more powerful and easier to use.
TestNG is an open source automated testing framework; where NG of TestNG means Next
Generation. TestNG is similar to JUnit especiallyJUnit4, but its not a JUnit extension. Its inspired by
JUnit. It is designed to be better than JUnit, especially when testing integrated classes. The creator
of TestNG is Cedric Beust.
TestNG eliminates most of the limitations of the older framework and gives the developer the
ability to write more flexible and powerful tests. As it heavily borrows from Java Annotations
introducedwithJDK5.0 to define tests, it can also show you how to use this new feature of the Java
language in a real production environment.
TestNG Features
Annotations.
TestNG uses more Java and OO features.
Supports testing integrated classes e. g. , bydefault, noneedtocreateanewtestclassinstanceforeverytestmethod.
Separate compile-time test code from run-time configuration/data info.
Flexible runtime configuration.
Introduces ‘test groups’. Once you have compiled your tests, you can just ask TestNG to run
all the "front-end" tests, or "fast", "slow", "database", etc...
Supports Dependent test methods, parallel testing, load testing, partial failure.
Flexible plug-in API.
Support for multi threaded testing.
ENVIRONMENT SET-UP
TestNG is a framework for Java, so the very first requirement is to have JDK installed in your
machine.
System Requirement
JDK
1.5 or above.
Memory
no minimum requirement.
Disk Space
no minimum requirement.
Operating System
no minimum requirement.
Step 1 - verify Java installation in your machine
Now, open console and execute the following java command.
OS
Task
Command
Windows
Open Command Console
c:\> java -version
Linux
Open Command Terminal
$ java -version
Mac
Open Terminal
machine:~ joseph$ java -version
Let's verify the output for all the operating systems:
OS
Output
Windows
java version "1.7.0_25"
JavaTM SE Runtime Environment build1.7.02 5 − b15
Java HotSpotTM 64-Bit Server VM build23.25 − b01, mixedmode
Linux
java version "1.7.0_25"
JavaTM SE Runtime Environment build1.7.02 5 − b15

Mac
java version "1.7.0_25"
JavaTM SE Runtime Environment build1.7.02 5 − b15
Java HotSpotTM 64-Bit Server VM build23.25 − b01, mixedmode
If you do not have Java installed, install the Java Software Development Kit SDK from
http://www.oracle.com/technetwork/java/javase/downloads/index.html. We are assuming Java
1.7.0_25 as installed version for this tutorial.
Step 2: Set JAVA environment
Set the JAVA_HOME environment variable to point to the base directory location, where Java is
installed on your machine. For example;
OS
Output
Windows
Set the environment variable JAVA_HOME to C:\Program
Files\Java\jdk1.7.0_25
Linux
export JAVA_HOME=/usr/local/java-current
Mac
export JAVA_HOME=/Library/Java/Home
Append Java compiler location to System Path.
OS
Output
Windows
Append the string ;C:\Program Files\Java\jdk1.7.0_25\bin to the end of the
system variable, Path.
Linux
export PATH=PATH: JAVA_HOME/bin/
Mac
not required
Verify Java Installation using java -version command explained above.
Step 3: Download TestNG archive
Download latest version of TestNG jar file from http://www.testng.org. At the time of writing this
tutorial, I downloaded testng-6.8.jar and copied it into C:\>TestNG folder.
OS
Archive name
Windows
testng-6.8.jar
Linux
testng-6.8.jar
Mac
testng-6.8.jar
Step 4: Set TestNG environment
Set the TESTNG_HOME environment variable to point to the base directory location, where
TestNG jar is stored on your machine. Assuming, we've stored testng-6.8.jar in TestNG folder on
various Operating Systems as follows.
OS
Output
Windows
Set the environment variable TESTNG_HOME to C:\TESTNG
Linux
export TESTNG_HOME=/usr/local/TESTNG
Mac
export TESTNG_HOME=/Library/TESTNG
Step 5: Set CLASSPATH variable
Set the CLASSPATH environment variable to point to the TestNG jar location. Assuming, we've
stored testng-6.8.jar in TestNG folder on various Operating Systems as follows.
OS
Output
Windows
Set the environment variable CLASSPATH to
%CLASSPATH%;%TESTNG_HOME%\testng-6.8.jar;
Linux
export CLASSPATH=CLASSPATH: TESTNG_HOME/testng-6.8.jar:
Mac
export CLASSPATH=CLASSPATH: TESTNG_HOME/testng-6.8.jar:
Step 6: Test TestNG Setup
Create a java class file name TestNGSimpleTest in C:\ > TestNG_WORKSPACE
import org.testng.annotations.Test;
import static org.testng.Assert.assertEquals;
public class TestNGSimpleTest {
@Test
public void testAdd() {
String str = "TestNG is working fine";
assertEquals("TestNG is working fine", str);
}
}
TestNG can be invoked in several different ways:
With a testng.xml file
With ant
From the command line
Let us invoke using the testng.xml file. Create an xml file with name testng.xml in C:\ >
TestNG_WORKSPACE to execute Test cases.
Step 7: Verify the Result
Compile the class using javac compiler as follows:
C:\TestNG_WORKSPACE>javac TestNGSimpleTest.java
Now, invoke the testng.xml to see the result.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.

WRITING TESTS
Writing a test in TestNG basically involves following steps:
Write the business logic of your test and insert TestNG annotations in your code.
Add the information about your test e. g. theclassname, thegroupsyouwishtorun, etc. . . in a testng.xml
file or in build.xml..
Run TestNG.
Here, we will see one complete example of TestNG testing using POJO class, Business logic class
and a test xml, which will be run by TestNG.
Create EmployeeDetails.java in C:\ > TestNG_WORKSPACE which is a POJO class.
public class EmployeeDetails {
private String name;
private double monthlySalary;
private int age;
/**
* @return the name
*/
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* @return the monthlySalary
*/
public double getMonthlySalary() {
return monthlySalary;
}
/**
* @param monthlySalary the monthlySalary to set
*/
public void setMonthlySalary(double monthlySalary) {
this.monthlySalary = monthlySalary;
}
/**
* @return the age
*/
public int getAge() {
return age;
}
/**
* @param age the age to set
*/
public void setAge(int age) {
this.age = age;
}
}
EmployeeDetails class is used to:
get/set the value of employee's name.
get/set the value of employee's monthly salary.
get/set the value of employee's age.
Create a EmpBusinessLogic.java in C:\ > TestNG_WORKSPACE which contains business logic.
public class EmpBusinessLogic {
// Calculate the yearly salary of employee
public double calculateYearlySalary(EmployeeDetails employeeDetails){
double yearlySalary=0;
yearlySalary = employeeDetails.getMonthlySalary() * 12;
return yearlySalary;
}
// Calculate the appraisal amount of employee
public double calculateAppraisal(EmployeeDetails employeeDetails){
double appraisal=0;
if(employeeDetails.getMonthlySalary() < 10000){
appraisal = 500;
}else{
appraisal = 1000;
}
return appraisal;
}
}
EmpBusinessLogic class is used for calculating.
the yearly salary of employee.
the appraisal amount of employee.
Now, let's create a TestNG class called TestEmployeeDetails.java in C:\ >
TestNG_WORKSPACE.A TestNG class is a Java class that contains at least one TestNG annotation.
This class contains test cases to be tested. A TestNG test can be configured by @BeforeXXX and
@AfterXXX annotations (we will see this in the chapter TestNG - Execution Procedure) which allows
to perform some Java logic before and after a certain point.
import org.testng.Assert;
import org.testng.annotations.Test;
public class TestEmployeeDetails {
EmpBusinessLogic empBusinessLogic = new EmpBusinessLogic();
EmployeeDetails employee = new EmployeeDetails();
@Test
public void testCalculateAppriasal() {
employee.setName("Rajeev");
employee.setAge(25);
employee.setMonthlySalary(8000);
double appraisal = empBusinessLogic
.calculateAppraisal(employee);
Assert.assertEquals(500, appraisal, 0.0, "500");
}
// test to check yearly salary
@Test
public void testCalculateYearlySalary() {
employee.setName("Rajeev");
employee.setAge(25);
employee.setMonthlySalary(8000);
double salary = empBusinessLogic
.calculateYearlySalary(employee);
Assert.assertEquals(96000, salary, 0.0, "8000");
}
}
TestEmployeeDetails class is used for testing the methods of EmpBusinessLogic class. It
tests the yearly salary of the employee.
tests the appraisal amount of the employee.
Before you can run the tests, however, you must configure TestNG using a special XML file,
conventionally named testng.xml. The syntax for this file is very simple, and its contents as below.
Create this file in C:\ > TestNG_WORKSPACE:
Details of the above file are as below:
A suite is represented by one XML file. It can contain one or more tests and is defined by the
tag.
Tag represents one test and can contain one or more TestNG classes.
tag represents a TestNG class is a Java class that contains at least one TestNG
annotation. It can contain one or more test methods.
Compile the Test case classes using javac.
C:\TestNG_WORKSPACE>javac EmployeeDetails.java EmpBusinessLogic.java
TestEmployeeDetails.java
Now TestNG with the following command:
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
If all has been done correctly, you should see the results of your tests in the console. Furthermore,
TestNG creates a very nice HTML report in a folder called test-output that is automatically
created in the current directory. If you open it and load index.html, you will see a page similar to
the one in the image below:
BASIC ANNOTATIONS
The traditional way to indicate test methods in JUnit 3 is by prefixing their name with test. This is a
very effective method for tagging certain methods in a class as having a special meaning, but the
naming doesn’t scale very well whatifwewanttoaddmoretagsfordifferentframeworks? and is rather inflexible
whatifwewanttopassadditionalparameterstothetestingframework?.
Annotations were formally added to the Java language in JDK 5 and TestNG made the choice to use
annotations to annotate test classes.
Here is the list of annotations that TestNG supports:
Annotation
Description
@BeforeSuite
The annotated method will be run only once before all tests in this suite
have run.
@AfterSuite
The annotated method will be run only once after all tests in this suite have
run.
@BeforeClass
The annotated method will be run only once before the first test method in
the current class is invoked.
@AfterClass
The annotated method will be run only once after all the test methods in the
current class have been run.
@BeforeTest
The annotated method will be run before any test method belonging to the
classes inside the tag is run.
@AfterTest
The annotated method will be run after all the test methods belonging to
the classes inside the tag have run.
@BeforeGroups
The list of groups that this configuration method will run before. This
method is guaranteed to run shortly before the first test method that
belongs to any of these groups is invoked.
@AfterGroups
The list of groups that this configuration method will run after. This method
is guaranteed to run shortly after the last test method that belongs to any of
these groups is invoked.
@BeforeMethod
The annotated method will be run before each test method.
@AfterMethod
The annotated method will be run after each test method.
@DataProvider
Marks a method as supplying data for a test method. The annotated method
must return an Object[][] where each Object[] can be assigned the
parameter list of the test method. The @Test method that wants to receive
data from this DataProvider needs to use a dataProvider name equals to the
name of this annotation.
@Factory
Marks a method as a factory that returns objects that will be used by TestNG
as Test classes. The method must return Object[].
@Listeners
Defines listeners on a test class.
@Parameters
Describes how to pass parameters to a @Test method.
@Test
Marks a class or a method as part of the test.
Benefits of using annotations
Following are some of the benefits of using annotations:
TestNG identifies the methods it is interested in by looking up annotations. Hence method
names are not restricted to any pattern or format.
We can pass additional parameters to annotations.
Annotations are strongly typed, so the compiler will flag any mistakes right away.
Test classes no longer need to extend anything suchasTestCase, forJUnit3.
EXCECUTION PROCEDURE
This tutorial explains the execution procedure of methods in TestNG which means that which
method is called first and which one after that. Here is the execution procedure of the TestNG test
API methods with the example.
Create a java class file name TestngAnnotation.java in C:\ > TestNG_WORKSPACE to test
annotation.
import
import
import
import
import
import
org.testng.annotations.Test;
org.testng.annotations.BeforeMethod;
org.testng.annotations.AfterMethod;
org.testng.annotations.BeforeClass;
org.testng.annotations.AfterClass;
org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.AfterSuite;
public class TestngAnnotation {
// test case 1
@Test
public void testCase1() {
System.out.println("in test case 1");
}
// test case 2
@Test
public void testCase2() {
System.out.println("in test case 2");
}
@BeforeMethod
public void beforeMethod() {
System.out.println("in beforeMethod");
}
@AfterMethod
public void afterMethod() {
System.out.println("in afterMethod");
}
@BeforeClass
public void beforeClass() {
System.out.println("in beforeClass");
}
@AfterClass
public void afterClass() {
System.out.println("in afterClass");
}
@BeforeTest
public void beforeTest() {
System.out.println("in beforeTest");
}
@AfterTest
public void afterTest() {
System.out.println("in afterTest");
}
@BeforeSuite
public void beforeSuite() {
System.out.println("in beforeSuite");
}
@AfterSuite
public void afterSuite() {
System.out.println("in afterSuite");
}
}
Next, let's create the file testng.xml in C:\ > TestNG_WORKSPACE to execute annotations.
Compile the Test case class using javac.
C:\TestNG_WORKSPACE>javac TestngAnnotation.java
Now, run the testng.xml, which will run test case defined in provided Test Case class.
C:\TestNG_WORKSPACE>java org.testng.TestNG testng.xml
Verify the output.

See the above output and this is how the TestNG execution procedure is:
First of all beforeSuite method is executed only once.
Lastly, the afterSuite method executes only once.
Even the methods beforeTest, beforeClass, afterClass and afterTest methods are executed
only once.
beforeMethod method executes for each test case but before executing the test case.
afterMethod method executes for each test case but after the execution of test case.
In between beforeMethod and afterMethod each test case executes.
EXECUTING TESTS
The test cases are executed using TestNG class. This class is the main entry point for running tests
in the TestNG framework. Users can create their own TestNG object and invoke it in many different
ways:
On an existing testng.xml
On a synthetic testng.xml, created entirely from Java
By directly setting the test classes.
You can also define which groups to include or exclude, assign parameters, etc. The command line
parameters are:
-d outputdir: specify the output directory
-testclass class_name: specifies one or several class names
-testjar jar_name: specifies the jar containing the tests
-sourcedir src1;src2: ; separated list of source directories usedonlywhenjavadocannotationsareused
-target
-groups
-testrunfactory
-listener
We will create the TestNG object an existing testng.xml in our example below.
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE
/*
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
//Constructor
//@param message to be printed
public MessageUtil(String message){
this.message = message;
}
// prints the message
public String printMessage(){
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say SampleTest.java.
Add a test method testPrintMessage to your test class.
Add an Annotation @Test to method testPrintMessage.
Implement the test condition and check the condition using assertEquals API of TestNG.
Create a java class file name SampleTest.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class SampleTest {
String message = "Hello World";
MessageUtil messageUtil = new MessageUtil(message);
@Test
public void testPrintMessage() {
Assert.assertEquals(message, messageUtil.printMessage());
}
}
Create testng.xml
Next, let's create testng.xml file in C:\ > TestNG_WORKSPACE to execute Test cases. This file
captures your entire testing in XML. This file makes it easy to describe all your test suites and their
parameters in one file, which you can check in your code repository or email to coworkers. It also
makes it easy to extract subsets of your tests or split several runtime configurations
e. g. , testng − database. xmlwouldrunonlyteststhatexerciseyourdatabase.
Compile the Test case using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java SampleTest.java
Now, run the testng.xml, which will run test case defined in tag.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.

SUITE TESTS
A Test suite is a collection of test cases that are intended to test a behavior or set of behaviors of
software program. In TestNG, we cannot define a suite in testing source code, but it is represented
by one XML file as suite is the feature of execution. This also allows flexible configuration of the
tests to be run. A suite can contain one or more tests and is defined by the tag.
is a root tag of your testng.xml. It describes a test suite, which in turn is made of several
sections.
Table below lists all the legal attributes accepts.
Attribute
Description
name
The name of this suite. It is a mandatory attribute.
verbose
The level or verbosity for this run.
parallel
Whether TestNG should run different threads to run this suite.
thread-count
The number of threads to use,if parallel mode is enabled ignoredother − wise.
annotations
The type of annotations you are using in your tests.
time-out
The default timeout that will be used on all the test methods found in this test.
In this chapter we will show you an example having two Test1 & Test2 test classes to run together
using Test Suite.
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > JUNIT_WORKSPACE
/*
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
// Constructor
// @param message to be printed
public MessageUtil(String message) {
this.message = message;
}
// prints the message
public String printMessage() {
System.out.println(message);
return message;
}
// add "Hi!" to the message
public String salutationMessage() {
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create Test Case Classes
Create a java class file name Test1.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class Test1 {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
Assert.assertEquals(message, messageUtil.printMessage());
}
}
Create a java class file name Test2.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class Test2 {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Manisha";
Assert.assertEquals(message,messageUtil.salutationMessage());
}
}
Now, let's write the testng.xml in C:\ > TestNG_WORKSPACE which would contain the
tag as follows:
Suite1 includes exampletest1 and exampletest2.
Compile all java classes using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java Test1.java Test2.java
Now, run the testng.xml, which will run test case defined in provided Test Case class.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.

IGNORE TESTS
Sometimes, it happens that our code is not ready and test case written to test that method/code
will fail if run. In such cases annotation @Testenabled = false helps to disable this test case.
A test method annotated with @Testenabled = false, then the test case that is not ready to test is
bypassed.
Now, let's see @Testenabled = false in action.
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE
/*
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
//Constructor
//@param message to be printed
public MessageUtil(String message){
this.message = message;
}
// prints the message
public String printMessage(){
System.out.println(message);
return message;
}
// add "Hi!" to the message
public String salutationMessage(){
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say IgnoreTest.java.
Add test methods testPrintMessage, testSalutationMessage to your test class.
Add an Annotation @Testenabled = false to method testPrintMessage.
Create a java class file name IgnoreTest.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class IgnoreTest {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test(enabled = false)
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
message = "Manisha";
Assert.assertEquals(message, messageUtil.printMessage());
}
@Test
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Manisha";
Assert.assertEquals(message, messageUtil.salutationMessage());
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases
Compile the MessageUtil, Test case classes using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java IgnoreTest.java
Now, run the testng.xml, which will not run testPrintMessage test case defined in provided Test
Case class.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output. testPrintMessage test case is not tested.

GROUP TEST
The group test is a new innovative feature in TestNG, it doesn’t exist in JUnit framework, it permits
you dispatch methods into proper portions and preform sophisticated groupings of test methods.
Not only can you declare those methods that belong to groups, but you can also specify groups
that contain other groups. Then, TestNG can be invoked and asked to include a certain set of
groups orregularexpressions while excluding another set. This gives you maximum flexibility in how you
partition your tests and doesn't require you to recompile anything if you want to run two different
sets of tests back to back.
Groups are specified in your testng.xml file using the tag. It can be found either under
the or tag. Groups specified in the tag apply to all the tags
underneath.
Now, let's see an example of how to group test.
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE
/*
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
// Constructor
// @param message to be printed
public MessageUtil(String message) {
this.message = message;
}
// prints the message
public String printMessage() {
System.out.println(message);
return message;
}
// add "tutorialspoint" to the message
public String salutationMessage() {
message = "tutorialspoint" + message;
System.out.println(message);
return message;
}
// add "www." to the message
public String exitMessage() {
message = "www." + message;
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say GroupTestExample.java.
Add test methods testPrintMessage, testSalutationMessage to your test class.
Group the test method in two categories say:
Check-in tests checkintest: These tests should be run before you submit new code. They
should typically be fast and just make sure no basic functionality is broken.
Functional tests functest: These tests should cover all the functionalities of your software
and be run at least once a day, although ideally you would want to run them
continuously.
Create the java class file name GroupTestExample.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class GroupTestExample {
String message = ".com";
MessageUtil messageUtil = new MessageUtil(message);
@Test(groups = { "functest", "checkintest" })
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
message = ".com";
Assert.assertEquals(message, messageUtil.printMessage());
}
@Test(groups = { "checkintest" })
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "tutorialspoint" + ".com";
Assert.assertEquals(message, messageUtil.salutationMessage());
}
@Test(groups = { "functest" })
public void testingExitMessage() {
System.out.println("Inside testExitMessage()");
message = "www." + "tutorialspoint"+".com";
Assert.assertEquals(message, messageUtil.exitMessage());
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases. Here, we would be
executing only those tests which belong to the group functest.
Compile the MessageUtil, Test case classes using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java GroupTestExample.java
Now, run the testng.xml, which will run only the method testPrintMessage as it belongs to the group
functest.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output. Only the method testPrintMessage is executed.

Groups can also include other groups. These groups are called MetaGroups. For example, you
might want to define a group all that includes checkintest and functest. Let's modify our testng.xml
file as below:
Executing the above testng.xml will execute all the three tests and will give you the below result:

Exclusion groups
You can ignore a group by using the tag as shown below:
EXCEPTION TEST
TestNG provides a option of tracing the Exception handling of code. You can test whether a code
throws desired exception or not. The expectedExceptions parameter is used along with @Test
annotation. Now let's see @TestexpectedExceptions in action.
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE.
Add a error condition inside printMessage method.
/*
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
//Constructor
//@param message to be printed
public MessageUtil(String message){
this.message = message;
}
// prints the message
public void printMessage(){
System.out.println(message);
int a =0;
int b = 1/a;
}
// add "Hi!" to the message
public String salutationMessage(){
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say ExpectedExceptionTest.java.
Add expected exception ArithmeticException to testPrintMessage test case.
Create a java class file name ExpectedExceptionTest.java in C:\ > TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class ExpectedExceptionTest {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test(expectedExceptions = ArithmeticException.class)
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
messageUtil.printMessage();
}
@Test
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Manisha";
Assert.assertEquals(message,messageUtil.salutationMessage());
}
}
Create Test Runner
Create a testng.xml in C:\ > TestNG_WORKSPACE to execute Test cases.
Compile the MessageUtil, Test case classes using javac
C:\TestNG_WORKSPACE>javac MessageUtil.java TestJunit.java
Now, run the Test Runner which will run test cases defined in provided Test Case class.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output. testPrintMessage test case will be passed.

DEPENDENCY TEST
Sometimes, you may need to invoke methods in a Test case in a particular order or you want to
share some data and state between methods. This kind of dependency is supported by TestNG as it
supports the declaration of explicit dependencies between test methods.
TestNG allows you to specify dependencies either with:
Using attributes dependsOnMethods in @Test annotations OR
Using attributes dependsOnGroups in @Test annotations.
Example using attribute dependsOnMethods
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE
public class MessageUtil {
private String message;
// Constructor
// @param message to be printed
public MessageUtil(String message) {
this.message = message;
}
// prints the message
public String printMessage() {
System.out.println(message);
return message;
}
// add "Hi!" to the message
public String salutationMessage() {
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say DependencyTestUsingAnnotation.java.
Add test methods testPrintMessage,testSalutationMessage and initEnvironmentTest to your
test class.
Add attribute dependsOnMethods = { "initEnvironmentTest" } to the @Test annotation of
testSalutationMessage method.
Create the java class file name DependencyTestUsingAnnotation.java in C:\ >
TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class DependencyTestUsingAnnotation {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
message = "Manisha";
Assert.assertEquals(message, messageUtil.printMessage());
}
@Test(dependsOnMethods = { "initEnvironmentTest" })
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Manisha";
Assert.assertEquals(message, messageUtil.salutationMessage());
}
@Test
public void initEnvironmentTest() {
System.out.println("This is initEnvironmentTest");
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases.
Compile the MessageUtil, Test case classes using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java DependencyTestUsingAnnotation.java
Now, run the testng.xml, which will run the testSalutationMessage method only after the execution
of initEnvironmentTest method.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.
This is initEnvironmentTest

Example using attribute dependsOnGroups
You can also have methods that depend on entire groups. Let's see an example below:
Create a Class
Create a java class to be tested say MessageUtil.java in C:\ > TestNG_WORKSPACE
public class MessageUtil {
private String message;
// Constructor
// @param message to be printed
public MessageUtil(String message) {
this.message = message;
}
// prints the message
public String printMessage() {
System.out.println(message);
return message;
}
// add "Hi!" to the message
public String salutationMessage() {
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create Test Case Class
Create a java test class say DependencyTestUsingAnnotation.java.
Add test methods testPrintMessage,testSalutationMessage and initEnvironmentTest to your
test class and them to the group "init".
Add attribute dependsOnMethods = { "init.*" } to the @Test annotation of
testSalutationMessage method.
Create the java class file name DependencyTestUsingAnnotation.java in C:\ >
TestNG_WORKSPACE
import org.testng.Assert;
import org.testng.annotations.Test;
public class DependencyTestUsingAnnotation {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);
@Test(groups = { "init" })
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
message = "Manisha";
Assert.assertEquals(message, messageUtil.printMessage());
}
@Test(dependsOnGroups = { "init.*" })
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Manisha";
Assert.assertEquals(message, messageUtil.salutationMessage());
}
@Test(groups = { "init" })
public void initEnvironmentTest() {
System.out.println("This is initEnvironmentTest");
}
}
In this example, testSalutationMessage is declared as depending on any group matching the
regular expression "init.*", which guarantees that the methods testPrintMessage and
initEnvironmentTest will always be invoked before testSalutationMessage.
If a method depended upon fails and you have a hard dependency on it
alwaysRun = false, whichisthedefault, the methods that depend on it are not marked as FAIL
but as SKIP. Skipped methods will be reported as such in the final report
inacolorthatisneitherrednorgreeninHTML, which is important since skipped methods are not
necessarily failures.
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases.
Compile the MessageUtil, Test case classes using javac.
C:\TestNG_WORKSPACE>javac MessageUtil.java DependencyTestUsingAnnotation.java
Now, run the testng.xml, which will run the testSalutationMessage method only after the execution
of initEnvironmentTest method.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.

dependsOnGroups Vs dependsOnMethods
On using groups, we are no longer exposed to refactoring problems. as long as we don’t
modify the dependsOnGroups or groups attributes, our tests will keep running with the
proper dependencies set up.
Whenever a new method needs to be added in the dependency graph, all we need to do is
put it in the right group and make sure it depends on the correct group. We don’t need to
modify any other method.
PARAMETERIZED TEST
Another interesting feature available in TestNG is parametric testing. In most cases, you'll come
across a scenario where the business logic requires a hugely varying number of tests.
Parameterized tests allow developer to run the same test over and over again using different
values.
TestNG lets you pass parameters directly to your test methods in two different ways:
With testng.xml
With Data Providers
Passing Parameters with testng.xml
With this technique you define the simple parameters in the testng.xml file and then reference
those parameters in source files. Let us see an example below on how to use this technique to pass
parameters.
Create Test Case Class
Create a java test class say ParameterizedTest1.java.
Add test method parameterTest to your test class. This method takes a String as input
parameter.
Add the annotation @Parameters"myName" to this method. The parameter would be passed
values from testng.xml which we will see in the next step.
Create the java class file name ParameterizedTest1.java in C:\ > TestNG_WORKSPACE
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class ParameterizedTest1 {
@Test
@Parameters("myName")
public void parameterTest(String myName) {
System.out.println("Parameterized value is : " + myName);
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases.
We can also define the parameters at the level. Suppose we have defined
myName at both and , levels then, in such cases regular scoping rules
apply. This means that any class inside tag will see the value of parameter
defined in , while the classes in the rest of the testng.xml file will see the value
defined in .
Compile the Test case class using javac.
C:\TestNG_WORKSPACE>javac ParameterizedTest1.java
Now, run the testng.xml, which will run the parameterTest method. TestNG will try to find a
parameter named myName first in the tag , and then, if it can’t find it, it searches in the
tag that encloses it.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml
Verify the output.
Parameterized value is : manisha

Total tests run: 1, Failures: 0, Skips: 0
===============================================
TestNG will automatically try to convert the value specified in testng.xml to the type of your
parameter. Here are the types supported:
String
int/Integer
boolean/Boolean
byte/Byte
char/Character
double/Double
float/Float
long/Long
short/Short
Passing Parameters with Dataproviders
When you need to pass complex parameters or parameters that need to be created from Java
complex objects, objects read from a property file or a database, etc..., in such cases parameters
can be passed using Dataproviders. A Data Provider is a method annotated with @DataProvider.
This annotation has only one string attribute: its name. If the name is not supplied, the Data
Provider’s name automatically defaults to the method’s name. A Data Provider returns an array of
objects.
Let us check out examples below of using Dataproviders. The first example is about
@DataProvider using Vector, String or Integer as parameter and the second example is about
@DataProvider using object as parameter
Example 1
Here, the @DataProvider passes Integer and Boolean as parameter.
Create Java class
Create a java class PrimeNumberChecker.java. This class checks if the number is prime. Create
this class in C:\ > TestNG_WORKSPACE
public class PrimeNumberChecker {
public Boolean validate(final Integer primeNumber) {
for (int i = 2; i < (primeNumber / 2); i++) {
if (primeNumber % i == 0) {
return false;
}
}
return true;
}
}
Create Test Case Class
Create a java test class say ParamTestWithDataProvider1.java.
Define the method primeNumbers which is defined as a Dataprovider using the annotation.
This method returns array of object array.
Add test method testPrimeNumberChecker to your test class. This method takes a Integer
and Boolean as input parameters. This method validates if the parameter passed is a prime
number.
Add the annotation @TestdataProvider = "test1" to this method. The attribute dataProvider is
mapped to "test1".
Create the java class file name ParamTestWithDataProvider1.java in C:\ > TestNG_WORKSPACE
import
import
import
import
org.testng.Assert;
org.testng.annotations.BeforeMethod;
org.testng.annotations.DataProvider;
org.testng.annotations.Test;
public class ParamTestWithDataProvider1 {
private PrimeNumberChecker primeNumberChecker;
@BeforeMethod
public void initialize() {
primeNumberChecker = new PrimeNumberChecker();
}
@DataProvider(name = "test1")
public static Object[][] primeNumbers() {
return new Object[][] { { 2, true }, { 6, false }, { 19, true },
{ 22, false }, { 23, true } };
}
// This test will run 4 times since we have 5 parameters defined
@Test(dataProvider = "test1")
public void testPrimeNumberChecker(Integer inputNumber,
Boolean expectedResult) {
System.out.println(inputNumber + " " + expectedResult);
Assert.assertEquals(expectedResult,
primeNumberChecker.validate(inputNumber));
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases.
Compile the Test case class using javac.
C:\TestNG_WORKSPACE>.javac ParamTestWithDataProvider1.java PrimeNumberChecker.java
Now, run the testng.xml.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml

19 true

Example 2
Here, the @DataProvider passes Object as parameter.
Create Java class
Create a java class Bean.java, which is simple object with get/set methods, in C:\ >
TestNG_WORKSPACE.
public class Bean {
private String val;
private int i;
public Bean(String val, int i){
this.val=val;
this.i=i;
}
public String getVal() {
return val;
}
public void setVal(String val) {
this.val = val;
}
public int getI() {
return i;
}
public void setI(int i) {
this.i = i;
}
}
Create Test Case Class
Create a java test class say ParamTestWithDataProvider2.java.
Define the method primeNumbers which is defined as a Dataprovider using the annotation.
This method returns array of object array.
Add test method testMethod to your test class. This method takes object bean as parameter.
Add the annotation @TestdataProvider = "test1" to this method. The attribute dataProvider is
mapped to "test1".
Create the java class file name ParamTestWithDataProvider2.java in C:\ > TestNG_WORKSPACE
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class ParamTestWithDataProvider2 {
@DataProvider(name = "test1")
public static Object[][] primeNumbers() {
return new Object[][] { { new Bean("hi I am the bean", 111) } };
}
@Test(dataProvider = "test1")
public void testMethod(Bean myBean) {
System.out.println(myBean.getVal() + " " + myBean.getI());
}
}
Create testng.xml
Create a testng.xml C:\ > TestNG_WORKSPACE to execute Test cases.
Compile the Test case class using javac.
C:\TestNG_WORKSPACE>javac ParamTestWithDataProvider2.java Bean.java
Now, run the testng.xml.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml

RUN JUNIT TESTS
Now that you have understood TestNG and its various tests, you must be worried by now as to how
to refactor your existing Junit code. There's no need to worry as TestNG provides a way to shift
from Junit to TestNG at your own pace. You can execute your existing Junit test cases using TestNG.
TestNG can automatically recognize and run JUnit tests, so you can use TestNG as a runner for all
your existing tests and write new tests using TestNG. All you have to do is to put JUnit library on the
TestNG classpath, so it can find and use JUnit classes, change your test runner from JUnit to TestNG
in Ant and then run TestNG in "mixed" mode. This way you can have all your tests in the same
project, even in the same package, and start using TestNG. This approach also allows you to
convert your existing JUnit tests to TestNG incrementally.
Let us see an example below and try out the above feature:
Create Junit Test case Class
Create a java class which is a Junit test class, TestJunit.java in C:\ > TestNG_WORKSPACE
import org.junit.Test;
import static org.testng.AssertJUnit.assertEquals;
public class TestJunit {
@Test
public void testAdd() {
String str= "Junit testing using TestNG";
assertEquals("Junit testing using TestNG",str);
}
}
Now, let's write the testng.xml in C:\ > TestNG_WORKSPACE which would contain the
tag as follows:
To execute the Junit test cases define property junit="true" as in the xml above. The Junit test case
class TestJunit is defined in class name.
For Junit 4, TestNG will use the org.junit.runner.JUnitCore runner to run your tests.
Compile all java classes using javac.
C:\TestNG_WORKSPACE>javac TestJunit.java
Now, run the testng.xml, which will run Junit test case as TestNG.
C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE:C:\TestNG_WORKSPACE\lib\junit4.11.jar" org.testng.TestNG testng.xml
Here I've placed the junit-4.11.jar under C:\TestNG_WORKSPACE\lib\junit-4.11.jar.
Verify the output.

TEST RESULTS
Reporting is the most important part of any test execution, reason being it helps the user to
understand the result of the test execution, point of failure, and reasons for the failure. Logging, on
the other hand, is important to keep an eye on the execution flow or for debugging in case of any
failures.
TestNG by default generates a different type of report for its test execution. This includes an HTML
and an XML report output. TestNG also allows its users to write their own reporter and use it with
TestNG. There is also an option to write your own loggers, which are notified at runtime by TestNG.
There are two main ways to generate a report with TestNG:
Listeners : For implementing a listener class, the class has to implement the
org.testng.ITestListener interface. These classes are notified at runtime by TestNG when the
test starts, finishes, fails, skips, or passes.
Reporters : For implementing a reporting class, the class has to implement an
org.testng.IReporter interface. These classes are called when the whole suite run ends. The
object containing the information of the whole test run is passed to this class when called.
The table below lists examples for different cases of reporting and logging:
Custom Logging
This example illustrates how to write your own logger.
Custom Reporter
This example illustrates how to write your own reporter.
HTML and XML
