CDP Testing & Quality Assurance

Question 1

Which testing approach aligns best with DevOps principles by integrating testing throughout the entire software delivery pipeline?

Accepted Answer

Shift-left testing

Answer

Shift-left testing moves quality checks earlier in the pipeline, catching defects sooner and reducing the cost of fixes in a DevOps workflow.

Question 2

In a DevOps pipeline, what is the primary purpose of a quality gate?

Accepted Answer

To enforce minimum quality criteria before promoting code to the next stage

Answer

Quality gates enforce minimum standards (coverage thresholds, zero critical bugs, etc.) that must be met before code advances to the next pipeline stage.

Question 3

Which type of test validates that individual functions or methods work correctly in isolation?

Accepted Answer

Unit test

Answer

Unit tests target the smallest testable units of code in isolation, providing fast feedback to developers without external dependencies.

Question 4

What does TDD (Test-Driven Development) require developers to do before writing production code?

Accepted Answer

Write a failing test first

Answer

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

Question 5

Which metric measures the percentage of code exercised by automated tests?

Accepted Answer

Code coverage

Answer

Code coverage measures what percentage of the codebase is executed during automated test runs, helping teams identify untested areas.
