Test-driven development improves code quality by enforcing a test-first coding practice where you write tests before implementation code. This ensures robust codebase behavior, prevents regression, and reduces uncertainty around functionality.

Implement a feature using red-green-refactoring by first writing a failing test, then writing minimal implementation code to pass the test, and finally refactoring to improve code quality and test efficiency. This enforces structured TDD cycles.

Use test-first coding practices when creating, debugging, and iterating over code to prevent regression and ensure robust codebase behavior. It is applicable across all software engineering roles focused on maximizing software quality.

Yes, test-driven development prevents regression bugs by ensuring code changes do not inadvertently introduce new bugs. By testing code first, it builds code confidence and reduces uncertainty around behavior during iterations.

The best way to structure tests before writing implementation code is to follow the red-green-refactoring framework. Start with a failing test for the specific feature, write just enough code to pass it, and then refactor to clean up the codebase.
