CAD Testing & Debugging

Question 1

What type of testing verifies that individual components or functions work correctly in isolation?

Accepted Answer

Unit testing

Answer

Unit testing focuses on testing individual components or functions in isolation to verify each piece works correctly on its own.

Question 2

Which debugging technique involves adding output statements to track program flow and variable values?

Accepted Answer

Print/log debugging

Answer

Print/log debugging inserts output statements to display variable values and execution flow without requiring specialized tooling.

Question 3

What is the purpose of a regression test?

Accepted Answer

To verify previously working functionality still works after code changes

Answer

Regression tests confirm that recent code changes have not broken functionality that was previously working correctly.

Question 4

In test-driven development (TDD), what is the correct order of steps?

Accepted Answer

Write test → Write code → Refactor

Answer

TDD follows the Red-Green-Refactor cycle: write a failing test first, write minimal code to pass it, then refactor for quality.

Question 5

What does 'code coverage' measure in a software testing context?

Accepted Answer

The percentage of source code executed during testing

Answer

Code coverage measures what percentage of the source code is actually executed when the test suite runs, indicating how thoroughly the code is tested.
