Test-driven development prevents bugs by requiring you to write and verify a failing test before writing any implementation code. This ensures code is verifiable and testable from the outset, guiding you through the Red-Green-Refactor cycle.

To start the Red-Green-Refactor cycle, write a failing test first. Then, write the minimal implementation code required to make that test pass. Finally, refactor the code for quality while ensuring the test continues to succeed.

The best way to enforce a test-first workflow is using a development process that mandates evidence submission for test failures and successes. This guarantees tests are written and observed to fail before any implementation code is created.

Yes, you must submit test results when refactoring code. The workflow requires mandatory evidence submission for both test failures and successes throughout the entire Red-Green-Refactor cycle to ensure continuous verification.

Yes, you can use this TDD workflow for any software development task requiring robust, verifiable code. It is broadly applicable to all development tasks, ensuring code quality and preventing bugs across different contexts.

A strict test-first development approach may not suit exploratory programming or rapid prototyping where requirements are highly unstable. It is designed for tasks requiring robust, verifiable code and strict quality enforcement from the outset.
