test-driven-development

Test-driven development is a coding practice where you write tests before implementation code, ensuring every feature is thoroughly tested to reduce debugging time and improve overall code quality.

To implement the red-green-refactor cycle, write a failing test, create minimal implementation code to pass it, and then refactor the code for better quality while keeping the tests green.

To start test-first coding for a new feature, write a failing test defining the expected behavior before writing any implementation code, ensuring your software development is testable from the start.

Yes, test-driven development reduces debugging time by catching defects early through automated testing, ensuring your implementation code consistently meets the specifications defined by your tests.

Best practices for automated testing in test-driven development include writing tests first, maintaining minimal implementation code to pass tests, and continuously refactoring to verify outcomes and ensure high code quality.

You might avoid test-first coding for exploratory spikes or throwaway prototypes where immediate code quality and automated testing verification are not required, though standard software development benefits from it.
