testing

Unit testing creates fast, isolated tests for individual functions. Write tests before code (TDD), aim for 80%+ coverage, keep tests independent with fixtures and mocks, and use parametrized tests to cover multiple scenarios efficiently across your language and framework.

Integration and end-to-end testing verify components work together. Build a test pyramid: many fast unit tests at the base, fewer integration tests in the middle, and minimal E2E tests at the top. Use consistent templates and maintain clear test documentation for reliable reporting.

TDD with CI/CD automates feedback: write tests first, commit code that passes them, and let CI pipelines run the full test suite automatically. This catches regressions early, enforces standards across the team, and maintains reliable deployments through regression verification.

Property-based testing generates random inputs to verify behavior holds universally. Security testing checks for vulnerabilities. Both integrate into comprehensive testing standards alongside unit and integration tests, supported across multiple languages and frameworks for production scenarios.

Enforce concrete requirements: define a test pyramid, set coverage targets above 80%, ensure unit tests are fast and isolated, maintain standard test templates, use parametrized tests, document execution steps, and establish consistent reporting across all languages and frameworks in your codebase.
