To implement features test-first, you start by writing a failing test, then write the minimal code required to pass that test, and finally refactor the code for clarity while maintaining passing tests.

Converting BDD scenarios into executable tests involves translating behavior-driven development steps into failing test cases, which then serve as the Red phase entry point for the test-driven development cycle.

You need an understanding of testing frameworks and iterative development principles to effectively write failing tests, implement passing code, and refactor within the test-driven development workflow.

For new feature development, the test-first approach requires writing a test that fails because the feature is missing, implementing minimal code to make it pass, and refactoring the implementation for better efficiency.

You should use the TDD Red-Green-Refactor methodology during agile development whenever you need to implement new features, ensuring code quality through iterative test creation and immediate code validation.
