Advanced Vitest Patterns

Become a Vitest superuser 🦹‍♀️

---

---

Prerequisites

• Prior experience with testing frameworks like Jest or Vitest is required.
• Basic level of TypeScript is recommended since all the exercises are written in TypeScript and you may have to write a type or two yourself.
• Visual Studio Code or Visual Studio Code-based editor is recommended as a few exercises feature extensions for that editor. The majority of the topics, however, is editor-agnostic.

Pre-workshop Resources

Here are some resources you can read before taking the workshop to get you up to speed on some of the tools and concepts we'll be covering:

• Why Vitest? and Vitest comparisons to other tools will give you a good understanding as to why we are using Vitest in this (and other) workshops.
• Working with Visual Studio Code Extensions Marketplace.

System Requirements

• git v2.18 or greater
• NodeJS v24 or greater
• npm v8 or greater

All of these must be available in your PATH. To verify things are set up properly, you can run this:

git --version
node --version
npm --version

If you have trouble with any of these, learn more about the PATH environment variable and how to fix it here for windows or mac/linux.
