Pragmatic Test-Driven Development in C# .NET

Learn how to apply TDD skills in your everyday .NET projects to produce robust software as well as utilize the power of TDD in C# to implement multiple useful features in your .NET projects Key Features * Build a full TDD-based app to help you practice real-world scenarios * Get up and running with TDD quickly by using specific features of Visual Studio * Know the challenges of rolling TDD into your organization and build a plan Book Description Test-driven development is a manifesto for incrementally adding features to a product but starting with the unit tests first. Today's project templates come with unit tests by default and implementing them has become an expectation. It's no surprise that TDD/unit tests are on most job specifications and are important ingredients of most interviews and coding challenges. Adopting TDD will enforce good design practices and expedite your journey toward becoming a better coding architect. This book goes beyond the philosophical debates and focuses on familiarizing you with TDD in a real-world setting by using popular frameworks such as ASP.NET and Entity Framework. The book starts with the foundational elements, before showing you how to use Visual Studio 2022 to build a To-Do application. To mimic real-life, you'll be using EF, SQL Server, and Cosmos, and utilize patterns including repository, service, and mediator. As a result of learning from this book, you'll also become familiar with domain-driven design (DDD) and other software best practices including SOLID and FIRSTHAND. By the end of this TDD book, you'll have become confident in championing a TDD implementation. You'll also be equipped with a business and technical case for rolling out TDD or unit testing to present to your management and colleagues. What you will learn * Write unit tests with xUnit and get to grips with dependency injection * Implement test doubles and mocking with NSubstitute * Use the TDD style for unit testing in conjunction with DDD and best practices * Mix TDD with the ASP.NET API, Entity Framework, and databases * Add the mediator design pattern and understand its effect on unit testing * Explore continuous integration with GitHub and Azure DevOps * Get introduced to advanced mocking scenarios and gain familiarity with Moq Who This Book Is For This book is for mid to senior-level .NET developers who are looking to utilize the potential of TDD to develop high-quality software. Basic knowledge of OOP and C# programming concepts is assumed but no knowledge of TDD or unit testing is expected. As the book provides in-depth coverage of all the concepts of TDD and unit testing, it acts as an excellent guide for developers who want to build a TDD-based application from scratch or developers planning to introduce unit testing into their organization.
