Unit testing with C# training provides participants with the skills to write and execute unit tests for C# applications using popular frameworks like MSTest, NUnit, and xUnit. The course covers key concepts such as setting up test projects, writing test cases, and using assertions to verify expected behavior in code. Participants also learn how to manage test dependencies, mock objects, and handle exceptions in unit tests. Hands-on exercises focus on creating testable code, organizing tests into suites, and ensuring high code coverage through automated tests. By the end of the training, attendees will be able to apply unit testing practices in their C# development workflow, enhancing code reliability and maintainability.

Basic knowledge of C# programming language.
Familiarity with object-oriented programming concepts like classes, methods, and properties.
No prior experience with unit testing is required.

Unit Testing with C#: Ability to write and execute unit tests for C# code using frameworks like NUnit and MSTest.
Mocking and Stubbing: Skill in using mocking libraries like Moq or NSubstitute to isolate code dependencies during testing.
Test-Driven Development (TDD): Understanding of test-first principles and how to apply them in C#.
Code Coverage and Quality: Ability to measure code coverage and ensure high code quality using unit testing.
