Udemy – Mastering C# Testing From Unit to Integration with Moq 2025-1

Mastering C# Testing From Unit to Integration with Moq. This course teaches you how to develop reliable, high-quality C# applications using a variety of testing methodologies. This course covers the fundamental concepts of testing, including Unit Testing with the AAA (Arrange, Act, Assert) pattern, types of Unit tests, and working with popular frameworks such as MSTest, NUnit, and xUnit. You will also learn how to simulate dependencies using Moq to create effective, independent tests. In the hands-on part, a real API is developed with .NET Core, and unit and integration tests are implemented with EF Core and SQL Server. By the end of the course, you will be able to write structured tests, handle complex scenarios, and ensure the correct operation of APIs with integration tests. This course is designed for C# developers who want to improve their testing skills and produce higher-quality software.
