testing

Test-driven development with Pest and Vitest follows the red-green-refactor loop: write a failing test first, implement minimal code to pass it, then refactor while keeping tests green. Pest handles PHP testing and Vitest handles JavaScript/React testing, with explicit commands like `composer test` and `npm run test` to run your test suite.

Yes. Pest, Vitest, and Playwright provide layered testing across PHP and JavaScript environments. Pest and Vitest handle unit and component tests with clear conventions, while Playwright automates end-to-end testing, allowing you to test feature interactions across your entire stack within standardized pipelines.

Coverage checks are built into Pest and Vitest test pipelines and can be run as part of standard test commands. Both frameworks generate coverage reports to identify untested code paths, helping you maintain reliability and enforce coverage thresholds in your CI/CD workflow.

Standardize testing workflows by applying consistent patterns: use Pest for Laravel unit and feature tests, Vitest for React component and unit tests, and Playwright for end-to-end scenarios. This approach codifies TDD practices, cross-framework conventions, and explicit test commands for write-run-verify cycles.

Yes, but the frameworks are purpose-built: Pest specializes in PHP testing with Laravel patterns, Vitest optimizes JavaScript/React testing, and Playwright handles browser automation. Learning each framework's conventions ensures your full stack benefits from dedicated tooling and TDD workflows.
