Software Testing- White Box

Branch testing focuses on testing:

• Every individual condition

• All the possible branches of control flow

• The overall system performance

• Error handling only

A branch in a program is defined by:

• Every decision point, such as if statements

• Every function call

• Every loop

• The program’s starting point

Statement testing aims to:

• Ensure all individual statements in the code are executed at least once

• Test all possible input conditions

• Test the system in a live environment

• Test the performance of the system

What is the main limitation of statement testing?

• It covers all edge cases

• It does not check for logical errors

• It requires multiple testers

• It doesn’t guarantee full code coverage

In path testing, the goal is to:

• Execute every line of code at least once

• Ensure all paths through the program are tested

• Test boundary conditions

• Check input validations

Path testing is most effective for:

• Complex systems with many conditional branches

• Simple systems with few branches

• Systems without loops

• Static applications

In loop testing, which of the following would be a valid test case?

• Test only the first iteration of a loop

• Test the condition inside the loop

• Test only the exit condition

• Test a loop that runs for exactly 10 iterations

Which of the following is a characteristic of loop testing?

• Focuses only on performance

• Tests various loop iteration conditions

• Tests boundary values only

• Tests complex system interactions

Which testing technique focuses on tracking how data moves and is modified within a program?

• Path testing

• Loop testing

• Data flow testing

• Regression testing

Data flow testing focuses on:

• The flow of data between different parts of a program

• The flow of control statements in a program

• The user interface design

• Testing memory usage
