Writing production code without tests leads to fragile software and regression risks; TDD reverses that by making tests the starting point to validate behavior.
Create a failing test for your new feature, then implement just enough code to make it pass.

Test-driven development prevents regressions by enforcing a test-first cycle where you write a failing test, implement minimal code to pass it, and refactor while preserving behavior. This ensures reliable software by validating requirements before coding.
The red-green-refactor cycle is a test-driven development workflow: write a failing test (red), implement just enough code to pass it (green), then refactor the code while keeping tests green. This drives safe design and validates behavior continuously.
To start test-first development, create a failing test that captures the new feature or bug fix requirements. Observe the red signal, then implement the minimal code required to make it pass, ensuring tests guide the design and document expectations.
Test-driven development works for refactoring by using tests to preserve existing behavior. You write tests to document current expectations, then refactor the code while ensuring the tests remain green, preventing regressions during structural changes.
You should avoid test-first development when writing exploratory code or throwaway prototypes where long-term reliability and regression safety are not concerns. TDD is designed for feature work, bug fixes, and refactors requiring validated behavior.
