Software Testing Fundamentals

Write robust, maintainable automated tests and practice test-driven development from day one. This hands-on course covers unit testing with xUnit, mocking with Moq, REST API validation, and continuous integration with GitHub Actions, giving you the skills to ensure code quality and reliability across your projects.

What You'll Learn

By the end of this course, you will be able to:

• Write unit tests and assertions using the xUnit framework
• Create parameterized tests, test fixtures, and edge case coverage for thorough validation
• Apply the Red-Green-Refactor TDD workflow to drive implementation through tests
• Mock objects and dependencies with Moq to isolate units and test asynchronous methods
• Write automated tests for REST APIs, validating responses, status codes, and edge cases
• Integrate tests into CI pipelines with GitHub Actions for automated execution on pull requests
