Test-driven development is a workflow requiring a failing test before writing production code. The red-green-refactor cycle drives this by first writing a failing test, implementing minimal code to pass it, then iteratively refactoring to maximize reliability and maintainability.

You enforce a test-first workflow by writing an explicit failing test that establishes correct behavior for a feature or bugfix. You then iterate using the red-green-refactor loop, writing minimal production code to satisfy the test requirements and prevent over-engineering.

Writing a failing unit test before implementation guides your design with concrete requirements and prevents over-engineering. It establishes the correct behavior upfront, ensuring your software engineering tasks produce reliable, well-tested features with maximum maintainability.

Yes, test-driven development is useful across software engineering tasks from small features to complex bug fixes. The red-green-refactor cycle scales to handle varying complexity by focusing on minimal production code and iterative refactoring to improve confidence.

The best way to prevent over-engineering is to drive feature development with a failing test first. By enforcing minimal production code that satisfies explicit test requirements through the red-green-refactor loop, you strictly limit code to what is necessary.
