To enforce the Red-Green-Refactor cycle, you need a mechanism that blocks implementation until a failing test is written, ensuring code follows test coverage. This approach mandates writing a failing test first, then minimal code to pass it, and finally refactoring while tests stay green.

Test-driven development is a practice where failing tests must precede implementation, preventing code from being written without test coverage. It enforces the Red-Green-Refactor cycle by blocking write and edit operations until adequate tests are established for features and bug fixes.

You can stop writing implementation code before establishing test coverage by enforcing test-first principles that block write and edit operations. This ensures adequate test coverage is created and verified through a failing test before any feature implementation begins.

Yes, you can use test-driven development for both new features and bug fixes. It enforces adherence to TDD principles across all development by mandating that a failing test precedes any code implementation, ensuring comprehensive coverage regardless of the task type.

A limitation of strictly enforcing test-first coding is that it blocks all write and edit operations without adequate test coverage. This rigid enforcement of the Red-Green-Refactor cycle may slow down rapid prototyping or exploratory coding where immediate test creation is not feasible.

Test-driven development requires a failing test before implementation to validate that the test actually checks the intended behavior. This Red-Green-Refactor cycle approach ensures code is only written after test coverage is established, preventing untested code from entering the codebase.
