testing-workshop-cypress

A full day testing workshop complete with application, exercise tests and speaker slides for Cypress.io

Requirements

• Any computer: Mac, Windows, Linux
• Node 12.0.0+ (LTS), check GH workflow file
• git
• An IDE like IntelliJ

In order to get the code and install dependencies

git clone https://github.com/mahasty-assi/testing-workshop-cypress
cd testing-workshop-cypress
npm install

If necessary, install dependencies inside TodoMVC folder (not always necessary)

cd todomvc
npm install

Quick check ✅

You can test the installation by starting TodoMVC in the first terminal window

cd todomvc
npm start

and you should see in the terminal

> json-server --static . data.json --middlewares ./node_modules/json-server-reset


  \{^_^}/ hi!

  Loading data.json
  Loading ./node_modules/json-server-reset
  Done

  Resources
  http://localhost:3000/todos

  Home
  http://localhost:3000

Note for Windows users: if npm start throws an error, it is probably due to cd todomvc; ... first command in the npm start script. In this case change the working folder to "todomvc" and run npm start from there.

From the second terminal window you should be able to open Cypress in the root of the project with

$ npm run cy:open

> testing-workshop-cypress@1.0.0 cy:open /git/testing-workshop-cypress
> cypress open

Tip

You can use the installed start-server-and-test utility to start the app, open Cypress and then shutdown the app when you exit Cypress.

$ npm run dev

Application 💾

Vue.js + Vuex + REST server application that we are going to test is in the folder todomvc. This application and its full testing is described in this blog post. The application should run fine without network access.
