Test-driven development in Laravel using Pest follows the Red-Green-Refactor workflow: write a failing Pest test asserting a specific behavior, implement the minimal code to pass it, then refactor. This ensures features are built reliably with consistent coverage before production.

Database testing in Laravel uses model factories to generate deterministic test data. By combining factories with PHPUnit or Pest, you can isolate database state for feature and integration tests, ensuring reliable and consistent test coverage across different testing layers.

Pest is the recommended default for Laravel testing due to its streamlined syntax, but PHPUnit should be used when existing project standards require it. Both frameworks support the Red-Green-Refactor cycle for unit, feature, and integration tests effectively.

Writing a feature test in Laravel involves using Pest or PHPUnit to assert a specific model behavior or HTTP response. You write the test first to define the expected outcome, then implement the application logic to make the test pass.

Test-driven development works effectively for refactoring and bug fixes in Laravel by ensuring existing behavior remains stable. You write tests that capture the current logic or reproduce the bug, then refactor the code or apply the fix to make all tests pass.
