🧪 Full Stack Testing

Confidently ship your full-stack app with automated tests

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.

Prerequisites

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:

System Requirements

git v2.18 or greater
NodeJS v20 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.

Setup

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 --depth to 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 setup

If you experience errors here, please open an issue with as many details as you can offer.

Exercises

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.

Running the app

To get the app up and running (and really see if it worked), run:

npm start

Now open your browser to the address that's logged out for you and you're good to get started!

Running the tests

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.

Launching your editor

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.
