A software development approach where tests are written before the actual code, following a red-green-refactor cycle to ensure code quality and maintainability. TDD requires developers to write failing tests first, then write minimal code to make them pass, then refactor. It supports the full software development lifecycle from design through deployment and maintenance and is foundational to agile and extreme programming methodologies.

| Name | Description |
|---|---|
| Red-Green-Refactor Cycle | Write failing tests first, implement minimal code to pass them, then refactor while keeping tests green. |
| Test Coverage Enforcement | Ensure all production code is covered by tests written before implementation. |
| Continuous Feedback | Get immediate feedback on code correctness through automated test runs on every change. |
| Design by Contract | Use failing tests to define the API contract and behavior before implementation begins. |
| Regression Prevention | Build a comprehensive regression suite as a side effect of the TDD development process. |
| Refactoring Safety | Refactor code with confidence knowing the full test suite will catch regressions. |
| Name | Description |
|---|---|
| API Design Validation | Use TDD to validate API contracts before writing implementation code. |
| Bug-Driven Development | Write a failing test that reproduces a bug before fixing it to prevent recurrence. |
| Legacy Code Modernization | Apply TDD when refactoring legacy code to ensure behavior is preserved. |
| Microservice Development | Use TDD to build well-tested microservice APIs with clear contracts. |
| Continuous Integration | Run TDD test suites automatically on every commit to maintain code quality. |
| Name | Description |
|---|---|
| GitHub Actions | Run TDD test suites automatically on pull requests using GitHub Actions workflows. |
