test-driven-development

Test-driven development is a practice where you write tests before implementation code. It improves code quality and reliability by validating features and bug fixes through comprehensive software testing.

To start a test-driven development cycle, write a failing test for the feature you want to implement. Then follow the Red-Green-Refactor cycle: make minimal code changes to pass the test, and finally refactor the implementation.

The Red-Green-Refactor cycle is a structured test-driven development approach. You iterate by writing a failing test, making minimal implementation changes to pass the test, and refactoring the code to ensure quality without breaking functionality.

Common anti-patterns in test-driven development include writing tests that are too broad or testing multiple behaviors at once. Following best practices ensures your tests validate specific features and bug fixes effectively without creating maintenance overhead.

Adopting test-first development requires an understanding of testing frameworks and coding standards. While no specific frameworks are mandated, you need an environment that supports running tests to validate your implementation code and ensure reliability.
