Test-Driven Development (TDD) for .NET Developers

Writing reliable software requires more than just writing code; it demands a disciplined approach to quality assurance. Test-Driven Development (TDD) is a crucial methodology for ensuring your code works exactly as intended before it even ships. This course teaches you the foundational principles of TDD, showing you how to integrate testing into your development workflow using C# and the powerful xUnit framework. You will transform from writing tests after the code to writing tests to drive the code's design. What you'll learn: * Understand the core philosophy and workflow of the Red, Green, Refactor TDD cycle. * Configure a modern .NET project and integrate the xUnit testing framework. * Practice writing focused, high-value unit tests following the Arrange, Act, Assert (AAA) pattern. * Apply TDD to design and implement new features while maintaining high code coverage. * Learn how to structure tests to isolate dependencies, preparing for complex application requirements. We start with essential testing terminology and setup, then move step-by-step through practical TDD implementation examples using C# code snippets. Each module builds practical skills through focused written exercises. This course is designed for absolute beginners to TDD and unit testing who have basic familiarity with C# and the .NET command line interface. No prior experience with xUnit or formal testing methodology is required. Start developing more robust and maintainable .NET applications today.
