CAD Continuous Integration and Testing Flashcards

What is the primary purpose of a CI build pipeline in an Agile development environment?

Answer: To automatically compile, test, and validate every code change merged into the shared repository

A CI pipeline automatically builds and tests each integration to catch defects early and maintain a releasable codebase.

Which testing strategy is most aligned with the Agile testing pyramid?

Answer: A large number of unit tests, fewer integration tests, and minimal end-to-end tests

The testing pyramid recommends many fast unit tests at the base, fewer integration tests in the middle, and a small number of slow end-to-end tests at the top.

In a CI workflow, what does 'breaking the build' typically indicate?

Answer: A committed change caused compilation errors or test failures in the shared branch

Breaking the build means a recent commit introduced code that fails to compile or passes existing tests, blocking the team.

What is the recommended response time for fixing a broken CI build in Agile practice?

Answer: It should be the team's top priority and fixed immediately

Agile teams treat a broken build as the highest priority because it blocks the entire team from integrating and validating further changes.

Which practice helps ensure that automated tests in a CI pipeline remain trustworthy?

Answer: Eliminating flaky tests and ensuring each test produces deterministic results

Flaky tests erode confidence in the CI pipeline, so teams must fix or remove non-deterministic tests to keep the suite reliable.

What is the main benefit of running static code analysis as part of a CI pipeline?

Answer: It detects code quality issues, security vulnerabilities, and style violations automatically before code review

Static analysis catches potential bugs, security flaws, and coding standard violations early without executing the code.
