C# Testing Practices Mastery: 60 NUnit Projects for Building Unit Tests, Mocks, and CI/CD Pipelines for Versatile Applications

By Leonard Brooks

C# Testing Practices Mastery is a comprehensive, hands-on guide designed for developers, QA engineers, test automation specialists, and software teams who want to elevate their testing expertise using the power of NUnit. This book goes far beyond simple syntax and test basics. It delivers 60 real-world, fully structured projects that demonstrate how to build high-quality, maintainable, and scalable unit tests for a wide range of C# applications.

Modern software development requires more than writing code-it relies on continuous testing, reliable automation, and seamless integration into CI/CD workflows. This book equips you with the practical skills to test effectively, automate confidently, and ship faster without compromising code quality.

Inside, you will learn how to design, implement, and optimize test suites using NUnit's robust features, and how to apply essential testing patterns to professional-grade .NET applications. Whether you are testing APIs, libraries, services, user interfaces, databases, or business logic, this guide offers structured, real-world examples that prepare you for enterprise-level development environments.
