1. Design and develop a program in a language of your choice to solve the
triangle problem defined as follows: Accept three integers which are
supposed to be the three sides of a triangle and determine if the three values
represent an equilateral triangle, isosceles triangle, scalene triangle, or they
do not form a triangle at all. Assume that the upper limit for the size of any
side is 10. Derive test cases for your program based on boundaryvalue
analysis, execute the test cases and discuss the results.
2. Design, develop, code and run the program in any suitable language to
solve the commission problem. Analyze it from the perspective of boundary
value testing, derive different test cases, execute these test cases and discuss
the test results.

ALGORITHM:
Step 1: Input a, b & c i.e three integer values which represent three sides of
the triangle.
Step 2: if (a < (b + c)) and (b < (a + c)) and (c < (a + b) then
do step 3
else
print not a triangle. do step 6.
Step 3: if (a=b) and (b=c) then
Print triangle formed is equilateral. do step 6.
Step 4: if (a ≠ b) and (a ≠ c) and (b ≠ c) then
Print triangle formed is scalene. do step 6.
Step 5: Print triangle formed is Isosceles.

Viva Questions
1. What is the MAIN benefit of designing tests early in the life
cycle?
It helps prevent defects from being introduced into the code.
2. What is the purpose of exit criteria?
The purpose of exit Criteria is to define when a test level is
completed.
3. What determines the level of risk?
The likelihood of an adverse event and the impact of the event
determine the level of risk.
4. When is used Decision table testing?
Decision table testing is used for testing systems for which the
specification takes the form of rules or cause-effect combinations.
In a decision table the inputs are listed in a column, with the
outputs in the same column but below the inputs. The remainder
of the table explores combinations of inputs to define the outputs
produced.
5. What is beta testing?
Testing performed by potential customers at their own locations.
6. We use the output of the requirement analysis, the
requirement specification as the input for writing …
User Acceptance Test Cases
7. What are the benefits of Independent Testing?
Independent testers are unbiased and identify different defects at
the same time.
8. In a REACTIVE approach to testing when would you expect
the bulk of the test design work to be begun?
The bulk of the test design work begun after the software or
system has been produced.
9. What are the phases of a formal review
In contrast to informal reviews, formal reviews follow a formal
process. A typical formal review process consists of six main
steps: Planning, Kick-off, Preparation, Review meeting,
Rework,Follow-up.

10. What is an equivalence partition (also known as an
equivalence class)?
An input or output ranges of values such that only one value in
the range becomes a test case.
11. What is negative and positive testing?
A negative test is when you put in an invalid input and receives
errors. While a positive testing, is when you put in a valid input
and expect some action to be completed in accordance with the
specification.
12. What is the purpose of a test completion criterion?
The purpose of test completion criterion is to determine when to
stop tes
13. What is the difference between re-testing and regression
testing?
Re-testing ensures the original fault has been removed;
regression testing looks for unexpected side effects.
14. Could reviews or inspections be considered part of testing?
Yes, because both help detect faults and improve quality.
15. How much testing is enough?"
The answer depends on the risk for your industry, contract and
special requirements.
16. Which of the following is the main purpose of the integration
strategy for integration testing in the small?
The main purpose of the integration strategy is to specify which
modules to combine when and how many at once.
17. What is test coverage?
Test coverage measures in some specific way the amount of
testing performed by a set of tests (derived in some other way,
e.g. using specification-based techniques). Wherever we can
count things and can tell whether or not each of those things has
been tested by some test, then we can measure coverage.
18. What is called the process starting with the terminal
modules?
Bottom-up integration
