tdd

The red-green-refactor workflow in test-driven development is a lifecycle of writing a failing test, making it pass, and then incrementally refactoring the code to ensure tests act as a reliable safety net.

To design testable interfaces for .NET solutions using TDD, you should focus on creating deep modules, establishing clear public interfaces, and avoiding horizontal slicing when planning your system boundaries.

You need mocking in test-driven development when verifying the behavior of system boundaries, allowing you to isolate the code under test and design public interfaces without relying on external dependencies.

The best way to start a new .NET project with a test plan is to apply test-driven development by planning your approach, laying down tracer bullets, and writing a test for the first behavior.

Yes, test-driven development works effectively with xUnit for .NET development, providing a structured approach to building software with tests first to enhance code quality and maintainability.

You should avoid horizontal slicing when writing testable code because it undermines the creation of deep modules and clear public interfaces, making tests less effective as a reliable safety net during refactoring.
