End-to-end testing mobile apps with Ionic and Cypress

Hello! This is the repository for the "End-to-end testing mobile apps with Ionic and Cypress" talk at Ioniconf 2020.

Talk Slides

This contains a fork of the Ionic Angular Conference Application.

The main branch contains the complete specs of Cypress tests written for the talk.

If you want to start from scratch and try it yourself, checkout the starter branch.

The following spec files are included and demonstrate specific test scenarios (in order from talk):

• iphone-5-critical-path.spec.js
• viewport.spec.js
• storage.spec.js
• swipe.spec.js

Running the App

Peep these awesome instructions straight from the ionic-conference-app repo:

Getting Started

• Download the installer for Node LTS.
• Install the ionic CLI globally: npm install -g ionic
• Clone this repository: git clone https://github.com/ionic-team/ionic-conference-app.git.
• Run npm install from the project root.
• Run ionic serve in a terminal from the project root.
• Profit. :tada:

Note: See How to Prevent Permissions Errors if you are running into issues when trying to install packages globally.

Running the Tests

Cypress is a dependency of this repo and will install in the previous step. You'll need to update the baseUrl in the cypress.json file to match the port where your app is running.

Cypress Open Mode

With the app running, in a new terminal run npx cypress open to open the Test Runner.

Click the iphone-5-critical-path.spec.js folder.

Watch the magic happen. :sparkle:

Cypress Run Mode

If you'd like to run your tests headlessly, in CI, or record the results to the Cypress Dashboard, you can bypass the Test Runner using npx cypress run instead.

There are a lot of fancy options you can pass, including specifying a browser, setting environment variables, and passing your record key for the Dashboard.
