React Component Testing with Vitest, The closer your tests resemble how your software is being used, the more confidence they will give you. There’s so many great patterns stemming from this simple rule, patterns I’m sure you’re already using to write better tests. Then, there’s the elephant in the room. Your test environment. For decades, web developers have been testing their UIs in make-believe environments that are neither the browser nor Node.js. It made them come up with a frankly ridiculous amount of test setup, polyfills, and workarounds just to make it work. Remember when you had to mock location in tests? window.matchMedia? Yeah… It’s time to abandon such practices. The tools have improved and there’s no excuse for you to be sleeping on it. It’s time for you to learn how to use Vitest Browser Mode for in-browser component testing! The first step in our journey is understanding why browser-like environments fall short. JSDOM has served us well, but it’s time to recognize its limitations. You’ll experience firsthand how browser-like environments like JSDOM are letting you down. We’ll explore examples of valid JavaScript code that works perfectly in browsers and Node.js but fails in JSDOM, undermining the value of the tests you work so hard to write. You’ll discover why these inconsistencies happen and why moving to real browser testing is the solution.
What you’ll learn
- In this workshop, you will learn a new approach to component testing that’s both different and the same. It is different because you will write and run your tests in the actual browser, taking advantage of the standard APIs and powerful browser automation. It is the same because it’s still the component level test you know and love, with rendering, querying, and asserting.
- Your users don’t interact with the UIs you build in JSDOM. They do that in the real browser, and now your tests will too!
Who this course is for
- This workshop is for all React developers who want to write reliable and valuable tests for their components. Whether you’re new to component testing or have been writing tests for years, you will inevitably learn new tools, APIs, and techniques to gain more value out of your test suite. That’s my sole motivation behind this material.
