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

• Any computer: Mac, Windows, Linux
• Node 6+
• git

In order to get the code and install dependencies

git clone [email protected]:cypress-io/testing-workshop-cypress.git
cd testing-workshop-cypress
npm install

If necessary, install dependencies inside TodoMVC folder

cd todomvc
npm install

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 with

$ npm run cy:open

> [email protected] cy:open /git/testing-workshop-cypress
> cypress open

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.

See the presentation at https://gitpitch.com/cypress-io/testing-workshop-cypress with the starting file in PITCHME.md presented using GitPitch. The pitch file includes files from the slides folder. Students should open the presentation slides and follow along. You can also show each section separately by clicking on the "slides" link in the table below. The full presentation includes all these presentations.

This workshop can take all day, but you can pick the sections you are interested in teaching at will and customize it into any time duration. Everyone is coding for the most part, except for CI and the Cypress Dashboard sections, where the usage was shown via slides and actual sites.

During the workshop, keep the todomvc app running in one shell, while each section 01-basic, 02-..., 03-... etc. has its own Cypress and specs subfolders cypress/integration/.... Usually a spec has several tests with placeholder comments. The workshop attendees are expected to make the tests pass using the knowledge from the slides and hints (and Cypress documentation). Note that most folders have a prepared spec.js file and an answer.js file. The answer.js file is ignored by Cypress using a setting in cypress.json.

The only exception is the folder 00-start. This is a folder for students to see how Cypress scaffolds example specs when you open Cypress for the very first time. In this folder students should execute...

cd 00-start
npm run cy:open

...and see the list of created example specs.

The slides can be shown directly via the presentation link above. The Markdown files in slides folder also has a little bit of speaker notes.

Every time a new Todo is saved or deleted, it changes file todomvc/data.json. To reset the list back to empty run npm run reset command.
