This guidance helps developers ensure reliable, maintainable software by forcing test cases before implementation, reducing regressions and clarifying expected behavior.
Run a test-first cycle: write a failing test, implement the minimal code to pass, and refactor.

Test-driven development improves software quality by enforcing a test-first workflow where developers write failing tests before coding. This prevents regressions, clarifies expected behavior, and detects design flaws early across features.
To implement a test-first workflow, write a failing test defining the desired feature, implement minimal code to make it pass, and refactor. This Red-Green-Refactor loop drives design decisions and ensures safer refactoring.
The Red-Green-Refactor cycle is a repeatable TDD loop: write a failing test (Red), implement minimal code to pass the test (Green), and clean up the code (Refactor). It drives design decisions and ensures higher code quality.
Use a test-driven development approach when you need reliable, maintainable software with safer refactoring. It is ideal for preventing production code without tests and ensuring quality assurance at early development stages.
Test-driven development does not mandate specific testing frameworks. It defines a repeatable cycle emphasizing clear intent and minimal implementation, allowing you to force test cases before implementation using your preferred tools.
