Test-Driven Development sounds abstract until you build something with it. This course makes it concrete by recreating the Wordle game from the very first failing test, using Vue 3 and the Composition API across 18 lessons while Vitest and Vue Test Utils drive every step.

The TDD workflow

You'll practice the Red-Green-Refactor loop repeatedly: write a failing test, make it pass with the smallest change possible, then clean up the code without breaking anything.

Testing skills covered

  • Writing tests that stay resilient as the game logic changes
  • Generating test cases instead of writing every scenario by hand
  • Using mocks and spies to isolate the code under test
  • Refactoring safely once your tests have your back

No prior testing experience is assumed, so it works equally well as a first introduction to TDD or a refresher for developers who already build Vue apps.

Frequently asked questions

What prior knowledge is required before taking this course?
The course is designed for developers at all levels, including those new to testing. While familiarity with JavaScript and basic web development concepts might be beneficial, the course does not require prior experience with Vue.js, TDD, or testing frameworks. It begins with foundational concepts like setting up your environment and understanding the basics of Test-Driven Development.
What will I build during the course?
Throughout the course, you will build a clone of the Wordle game. This involves implementing game features such as handling player input, allowing multiple guesses, displaying all guesses, and providing hints after each submission. The project serves as a practical application of Test-Driven Development using Vue.js.
Who is the target audience for this course?
The course is suitable for developers at all levels, from beginners to more experienced coders who are new to testing. It is particularly useful for those interested in learning how to apply Test-Driven Development practices using Vue.js and related testing tools.
What specific tools and technologies are covered in this course?
This course covers Vue.js 3, the Composition API, Vitest, and Vue Test Utils. These tools are utilized to implement Test-Driven Development practices, such as the Red-Green-Refactor loop, crafting tests, and using mocks and spies.
How does this course compare in depth and scope to other TDD courses?
This course focuses specifically on Test-Driven Development using Vue.js by building a Wordle clone. It emphasizes practical application of TDD principles, including defining game rules, handling input, and writing regression tests. The course also covers advanced topics like test generators and visual regression tests, making it a specialized course for those interested in applying TDD within the Vue.js ecosystem.
What topics are not covered in this course?
The course does not cover advanced Vue.js topics outside the scope of Test-Driven Development, such as Vue Router or Vuex for state management. It focuses strictly on TDD practices and the development of a Wordle clone using specific testing tools and techniques.
What is the expected time commitment to complete this course?
The course consists of 18 lessons. While the exact runtime is not specified, students should allocate time for both learning and hands-on practice, especially when working through the process of building the Wordle clone and applying TDD techniques. The practical nature of the course may require additional time for coding exercises and experimentation.
