Backend testing for REST APIs requires comprehensive unit, integration, and API tests. This skill provides step-by-step guidance for covering critical paths including database operations and authentication flows across common stacks like Node.js, Django, Flask, and Spring.

Effective mocking strategies for integration tests isolate dependencies and enforce test coverage. This skill demonstrates test organization and mocking techniques using frameworks like Jest, Pytest, Mocha, and JUnit to ensure business logic is validated accurately.

Yes, this backend testing guidance supports Python frameworks like Django and Flask, alongside Java's Spring. It applies testing strategies, coverage targets, and CI integration using compatible tools such as Pytest for Python and JUnit for Java.

Integrating unit and API tests into CI/CD pipelines requires enforcing test strategies and coverage targets. This skill guides you through CI integration using standard tools like Jest, Pytest, Mocha, and JUnit to run full test suites automatically.

Unit tests validate individual business logic components, while integration tests verify database operations and authentication flows. This skill helps determine the appropriate test strategy and coverage targets to ensure critical backend paths are fully covered.
