Course Description:

🔍 Understanding the Importance of Unit Testing: Testing is not just a developer's best friend; it's an essential part of the software development lifecycle. While coding can be an exhilarating experience, it's crucial to ensure that our codebase remains robust and reliable as it grows in complexity. Did you know that 7 out of 10 bugs are actually due to incorrect user input? This means that only 1 out of 10 issues is a direct result of developer error! But fear not, because with the right testing strategies, we can catch these errors early and often.

🧠 The Core of Reliable Software: As developers, it's our responsibility to make sure that our code works as expected under various conditions. We can't predict everything a user might do, but we can test the logic within our application to ensure it behaves correctly. This is where unit testing comes into play – it allows us to test small, isolated parts of our code, such as methods and functions, in isolation from the rest of the system.

Course Highlights:

• Introduction to Unit Testing in C#: We'll begin by understanding what unit testing is and why it's essential for your projects.

• Choosing Your Test Framework: I'll introduce you to both NUnit and XUnit, the two leading test frameworks for C# and .NET. You'll learn the differences between them and decide which one suits your needs best.

• Mastering Assertions: Assertions are the backbone of unit tests. You'll learn how to use assertions effectively to validate your assumptions about the code's behavior.

• Exception Testing: Learning how to write tests for exception handling is crucial. I'll guide you through testing functions that can throw exceptions under certain conditions.

• Mocking Objects: Mocking complex dependencies or external services is a powerful technique. You'll discover how to isolate the code units and test them in their purest form, without relying on external systems.

Practical Learning with Real Examples:

• Hands-On Practice: I will provide you with practical examples and exercises that will help you understand and implement unit testing in your own projects.

• Step-by-Step Guidance: From setting up your test environment to writing your first unit tests, I'll be with you every step of the way.
