Automated Testing In C# 14
 

Modern C# applications often evolve quickly, and without a solid testing strategy, teams risk regressions, brittle code, and fragile deployments.
Modern C# applications often evolve quickly, and without a solid testing strategy, teams risk regressions, brittle code, and fragile deployments. In this course, Automated Testing in C#, you'll gain the ability to build reliable, maintainable tests that validate your application from individual units of logic all the way to real infrastructure components. First, you'll explore how to write clear and focused unit tests, including data‑driven tests, exception testing, and snapshot testing for complex object graphs. Next, you'll discover how to design testable code using abstractions and mocks, and how to apply a practical test‑driven development (TDD) workflow. Finally, you'll learn how to create robust integration tests for file system components, use a real SQL Server instance running in Docker as part of your integration test suite with Testcontainers, and run your full test suite automatically in a GitHub action. When you're finished with this course, you'll have the skills and knowledge of automated testing in C# needed to confidently verify behavior, refactor safely, and deliver robust, high‑quality .NET applications.
