Frequently Asked Questions about testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run unit tests and E2E tests before merging code changes?▼

Run unit and E2E tests using the provided script commands to verify code changes and prevent regressions. This pre-merge verification ensures that existing functionality remains intact before integration.

What are the principles for writing effective unit tests?▼

Write tests that are deterministic, independent, fast, focused, and descriptive. These testing principles ensure maintainable test suites that accurately validate code quality and prevent regressions.

How do I debug test failures in my CI/CD pipeline?▼

Debug test failures by running the provided test commands locally to reproduce the CI/CD failure. Use the testing guidelines to isolate broken functionality and verify the code changes causing the regression.

Do I need to run unit and E2E tests separately for backend and frontend?▼

Execute backend unit tests and frontend E2E tests separately using distinct script commands. This separation ensures focused, fast, and deterministic test execution for each application layer.

What's the best way to ensure code quality and prevent regressions before a commit?▼

Follow the pre-merge verification checklist to ensure code quality before commits. Run all relevant unit and E2E tests to verify that no existing functionality is broken by recent code changes.
