Tests often couple to implementation, making refactors painful; TDD emphasizes validating behavior through public interfaces so tests remain robust to internal changes.
Begin with a tracer bullet: write one failing test for the desired behavior, then implement only enough code to pass it.

To prevent tests from breaking during refactoring, validate behavior through public interfaces rather than coupling to internal implementation details. This test-driven development approach ensures your tests remain robust when internal code structures change.
The tracer bullet workflow in test-driven development involves writing a single failing test for one behavior, then implementing just enough code to pass it. This vertical slicing method builds features incrementally through disciplined red-green-refactor cycles.
To start test-driven development for a new feature, begin with a tracer bullet: write one failing test for the desired behavior, then implement only enough code to pass it. Follow this with iterative refinement and disciplined refactoring.
Integration tests are used in test-driven development because they exercise real code paths through public APIs, ensuring software behaves correctly end-to-end. This approach validates actual behavior rather than testing isolated implementation details.
Yes, test-driven development can be applied to bug fixes across projects. You write a failing test that reproduces the bug, implement the fix to make it pass, and then refactor the code while maintaining fast incremental feedback.
Test-driven development may not suit contexts where fast incremental feedback is impossible or where public interfaces are unstable. The approach requires disciplined cycles of planning, testing, implementing, and refactoring to be effective.
