To enforce Test-Driven Development, follow the RED-GREEN-REFACTOR cycle by writing a failing test first, implementing minimal code to pass it, and then refactoring. This prevents untested code from being deployed.

The best way to fix bugs using TDD is to first write a test that reproduces the exact bug. Once the failing test confirms the issue, write the minimal implementation code to make it pass and ensure the bug is resolved.

The RED-GREEN-REFACTOR methodology improves code quality by requiring failing tests before implementation, ensuring every software development feature has robust, verifiable tests from the outset and preventing untested code.

Yes, you can apply TDD discipline for behavior modification in agile development. It guides you through writing tests for the new behavior first, ensuring changes are verifiable and preventing untested modifications from shipping.

You should never write implementation code before tests in software development if you want to prevent untested code. The TDD methodology discourages writing implementation until a failing test exists to verify the intended behavior.

To start writing code with TDD, you need an environment capable of running tests to verify the RED-GREEN-REFACTOR cycle. The methodology relies on executing tests to confirm failures and validate minimal passing code.
