test-driven-development

Test-driven development improves code quality and reliability by following a Red-Green-Refactor cycle. This structured approach ensures every piece of code has a corresponding test, leading to more robust and reliable software with fewer regressions.

The Red-Green-Refactor cycle in test-driven development is a guiding principle for writing effective code incrementally. You write a failing test, implement code to pass that test, and then refactor the code to improve its structure while maintaining reliability.

Yes, you need an understanding of testing frameworks and coding practices to use test-driven development. This prerequisite knowledge is required to effectively implement features or fix bugs while ensuring software quality through automated testing.

You should use a test-first approach for software development when you want to adopt a more structured approach to coding. It is suitable for improving code quality and reliability by ensuring every feature or bugfix has a corresponding automated test.

Automated testing catches regressions in test-driven development by running predefined tests against new code changes. This ensures that existing functionality remains intact and reliable throughout the software development workflow.
