B.S.W.E. Bachelor of Software Engineering Software Testing & Quality Assurance

Question 1

What is the difference between white-box and black-box testing?

Accepted Answer

White-box tests internal code structure; black-box tests external behavior only

Answer

White-box testing examines internal code structure and logic paths, while black-box testing focuses on external behavior without knowledge of the implementation.

Question 2

What is unit testing?

Accepted Answer

Testing individual functions or components in isolation

Answer

Unit testing involves testing individual units of code (functions or methods) in isolation from the rest of the system to verify correctness.

Question 3

What does TDD stand for and what is its key practice?

Accepted Answer

Test Driven Development — write tests before writing code

Answer

Test Driven Development (TDD) is a methodology where you write a failing test first, then write code to make it pass, then refactor.

Question 4

What is regression testing?

Accepted Answer

Re-running tests to ensure existing functionality still works after changes

Answer

Regression testing re-runs existing tests after code changes to verify that previously working functionality has not been unintentionally broken.

Question 5

What is the purpose of integration testing?

Accepted Answer

Testing how multiple components work together as a group

Answer

Integration testing verifies that different modules or services interact correctly when combined, catching defects at component interfaces.
