test-driven-development

The test-driven development workflow follows a structured red-green-refactor cycle: write a failing test, implement minimal code to pass it, and then refactor. This process ensures high-quality, maintainable software by emphasizing structured testing cycles and best practices to reduce bugs.

To implement test-driven development, start by writing a failing test for the desired function. Next, write the minimal code required to pass that test. Finally, refactor the code while ensuring the tests still pass, repeating this cycle until the feature is complete.

Yes, test-driven development is applicable to general software engineering tasks. It provides educational content and guided workflows that help developers implement features reliably, making it suitable for both new project onboarding and ongoing development to ensure quality from the start.

The best way to avoid errors in TDD is to strictly follow the structured testing cycle and adhere to best practices. By writing tests first and implementing only the minimal code needed to pass them, you prevent over-engineering and ensure continuous error avoidance.

Test-driven development improves code quality by forcing developers to define success criteria through failing tests before implementation. The subsequent refactoring step ensures the code remains clean and maintainable while the tests provide a safety net against future regressions.
