Black-box testing evaluates software functionality purely based on inputs and expected outputs, with no visibility into internal code.

Question 3

What does regression testing primarily aim to verify?

Accepted Answer

That previously working functionality still works after code changes

Answer

Regression testing ensures that recent code changes or additions have not broken previously working functionality.

Question 4

Which type of testing simulates real-world user traffic to evaluate system behavior under expected and peak conditions?

Accepted Answer

Load testing

Answer

Load testing simulates realistic user volumes to measure how a system performs under expected and peak traffic scenarios.

Question 5

What is a test case?

Accepted Answer
