In this workshop you'll get practical skills you need to write tests well. So it's less of a chore you dread, and more of a part of the process of developing quality software in which you can have confidence.
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:
- Playwright
- Vitest
- Testing Library
- Testing Library Queries
- But really, what is a JavaScript test?
- But really, what is a JavaScript mock?
- Testing Implementation Details
- Avoid the Test User
- Common mistakes with React Testing Library
- Common Testing Mistakes
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 --versionIf 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.
This is a pretty large project (it's actually many apps in one) so it can take several minutes to get everything set up the first time. Please have a strong network connection before running the setup and grab a snack.
Warning: This repo is very large. Make sure you have a good internet connection before you start the setup process. The instructions below use
--depthto limit the amount you download, but if you have a slow connection, or you pay for bandwidth, you may want to find a place with a better connection.
Follow these steps to get this set up:
git clone --depth 1 https://github.com/epicweb-dev/full-stack-testing.git
cd full-stack-testing
npm run setupIf you experience errors here, please open an issue with as many details as you can offer.
You'll find all the exercises in the exercises directory. The structure of the
workshop apps is described below, but most of the time you should be able to
simply run the app and navigate around the different exercises using the
application (there are even buttons to open the right exercise file right in
your editor).
The purpose of the exercise is not for you to work through all the material. It's intended to get your brain thinking about the right questions to ask me as I walk through the material.
To get the app up and running (and really see if it worked), run:
npm startNow open your browser to the address that's logged out for you and you're good to get started!
The test script in the package.json runs the tests on the solutions (these
should all pass). To run the tests against your own work, you simply open the
problem page and click the "Test" tab.
The application has several buttons which will launch your editor to the right file. There are a lot of files in this workshop so you'll be using this feature a lot to get to the right place at the right time.
This should just work™️, but if it doesn't it could be that our editor guessing
isn't working for you. If that's the case, create a .env file in the root of
this project and add an environment variable called EPICSHOP_EDITOR with the
value being set to the path to your editor's executable. For example, if you're
using VS Code on Windows, you'd add this to your .env file:
EPICSHOP_EDITOR="C:\Program Files\Microsoft VS Code\bin\code.cmd"
Make certain that if the path includes spaces that you wrap the path in quotes as above.

Each exercise has comments in it to help you get through the exercise. These fun emoji characters are here to help you.
- Kody the Koala 🐨 will tell you when there's something specific you should do
- Lily the Life Jacket 🦺 will help you with any TypeScript-specific parts of the exercises
- Marty the Money Bag 💰 will give you specific tips (and sometimes code) along the way
- Nancy the Notepad 📝 will encourage you to take notes on what you're learning
- Olivia the Owl 🦉 will give you useful tidbits/best practice notes
- Dominic the Document 📜 will give you links to useful documentation
- Barry the Bomb 💣 will be hanging around anywhere you need to blow stuff up (delete code)
- Matthew the Muscle 💪 will indicate that you're working with an exercise
- Chuck the Checkered Flag 🏁 will indicate that you're working with a final
- Peter the Product Manager 👨💼 helps us know what our users want
- Alfred the Alert 🚨 will occasionally show up in the test failures with potential explanations for why the tests are failing
- Kellie the Co-worker 🧝♀️ your co-worker who sometimes does work ahead of your exercises
Each exercise has an Elaboration and Feedback link. Please fill that out after the exercise and instruction.
