Test-driven development is enforced by applying a structured workflow that mandates writing tests before implementation across features, bug fixes, and refactoring tasks. This ensures code is written with tests first and meets coverage targets, reducing regression risk.

Achieving 80%+ test coverage requires a repeatable workflow: write user journeys, generate tests, run tests, implement code, and verify coverage across test types. This structured approach ensures coverage goals are consistently met during development.

Begin a test-first workflow by outlining a user journey and generating corresponding tests. Then implement the code to satisfy the tests and re-run them until the 80%+ coverage goals are met across all test types.

Yes, test-first coding applies to bug fixes and refactoring. Enforcing tests-before-code principles during these tasks reduces regression risk and enables reliable refactors by validating changes against existing and new tests.

Writing user journeys before generating tests provides a structured workflow that defines expected application behavior upfront. This ensures the generated unit, integration, and end-to-end tests accurately reflect requirements before code implementation begins.

A strict test-first workflow ensures high test coverage and reduces regression risk, but it may require more initial time for writing user journeys and tests. It is less suited for rapid prototyping where requirements are highly unstable and code will be discarded.
