About this course

Writing software that is easy to maintain and free of bugs requires a structured approach to quality from the very first line of code. Test-Driven Development (TDD) shifts quality to the forefront of your development process, ensuring your TypeScript applications are robust by design. This text-based course guides you through the foundational principles of TDD using TypeScript. You will transition from writing code first to designing software through tests, resulting in loosely coupled architectures and highly reliable applications. What you'll learn: - Understand the core philosophy of TDD, including the red-green-refactor cycle and its benefits. - Write clean, maintainable unit tests for TypeScript applications using modern testing frameworks. - Apply test doubles, mocks, and stubs to isolate components and write highly decoupled code. - Design type-safe test suites that leverage TypeScript's powerful type system to catch errors early. - Implement user requirements step-by-step by translating user stories into executable test cases. - Refactor existing code with confidence, knowing your test suite guarantees application stability. The course starts with essential testing concepts and terminology before guiding you through practical, text-based coding exercises that build your confidence in the TDD workflow. This course is designed for beginner TypeScript developers who want to adopt professional testing practices; no prior experience with testing or TDD is required. Start building more reliable software today by mastering the fundamentals of test-driven development.

Pretty good introduction. The examples were helpful, but I wish there was a bit more practice material. Solid value for the cost.

Good introduction. I appreciated the clear steps, although some of the later modules could have used more examples.

Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.

Found it a bit dry, tbh. The examples weren't always the most relevant, making it hard to stay engaged through some of the modules.
