test-driven-development

Test-driven development enforces the red-green-refactor cycle by requiring a failing test before production code, implementing minimal logic to pass, and refactoring with ongoing validation to maintain software quality.

Start writing failing tests by defining expected behavior first, running the test to confirm failure, implementing the minimal code required to pass, and refactoring for maintainability while continuously validating the tests.

Yes, you can apply test-driven development workflows across diverse languages and test frameworks. The discipline enforces a consistent testing process for feature implementation, bug fixes, and refactoring regardless of the specific technology stack.

The best way to fix bugs using test-driven development is to write a failing test that reproduces the bug first, implement the minimal code to pass the test, and refactor with ongoing validation to prevent regressions.

Test-driven development requires running tests to confirm failure first to validate that the test accurately captures the missing functionality, ensuring production code is only written to satisfy a properly failing test.

No, you do not need pytest specifically. Test-driven development applies across diverse languages and test frameworks, enforcing the same red-green-refactor discipline regardless of the specific testing tool used.
