Test-driven development implements features by writing automated tests for expected behavior before writing production code. You follow the Red-Green-Refactor cycle: write a failing test, write code to make it pass, then refactor.

The Red-Green-Refactor cycle in TDD is a process where you first write a failing test, then write the minimum production code required to make it pass, and finally refactor the code for quality without breaking functionality.

Test-driven development helps fix bugs by creating automated tests that target specific error scenarios and edge cases before patching the code. This reduces the risk of introducing new errors and ensures comprehensive test coverage.

Yes, you need familiarity with testing frameworks and an understanding of basic programming concepts to effectively write automated tests before production code and manage the test-driven development workflow.

You should use a test-first approach when developing a new feature that requires high reliability. Start by defining the desired behavior through an automated test to ensure your production code meets specifications safely.

TDD requires upfront time to write automated tests before production code, which may slow initial feature delivery. It also demands familiarity with testing frameworks to properly handle edge cases and maintain the Red-Green-Refactor cycle.
