test-driven-development

Writing tests first requires defining a failing test for your new feature before any production code is written. You then implement the minimal code needed to make that test pass, ensuring code reliability from the start.

The red-green-refactor cycle in test-driven development is a loop where you first write a failing test, then write minimal code to make it pass, and finally refactor the code while keeping the test green.

Strict test-driven development handles bug fixes and refactoring by enforcing a no production code without a failing test first principle. You must reproduce the bug with a failing test before fixing it, ensuring the refactor is verified.

Yes, you need to write a failing test before writing any production code. This strict adherence to the test-driven development methodology prevents bugs and improves overall code quality by validating requirements upfront.

Yes, you can use test-driven development for both new features and debugging. The methodology enforces writing a failing test first to capture the desired behavior or reproduce the bug, followed by minimal implementation to pass the test.

The best way to ensure code quality through testing is to mandate the red-green-refactor cycle. This prevents bugs by requiring a failing test before implementation and validating minimal code changes immediately.
