This project was bootstrapped with Create React App v3.

npm install
npm start

The above commands will install dependencies and start the app. To run tests, run npm test on a separate command line. There are no tests written in the master branch.

Tip: to start the application and the mock API and open Cypress, you can use start-server-and-test utility.

npm run dev

This instance of create-react-app has been enhanced with the following testing libraries:

When you run the application with npm start it instruments the source code using @cypress/instrument-cra module. The code coverage is collected using @cypress/code-coverage plugin and saved in coverage folder.

Important: your application should have been created using CRA v3 and include react-scripts v2+.

First, add NPM module @cypress/instrument-cra as a dev dependency

npm install --save-dev @cypress/instrument-cra

Load this module when starting the application in package.json

{
  "scripts": {
    "start": "react-scripts -r @cypress/instrument-cra start"
  }
}

Your application's source code should be instrumented when you run npm start. Then you can use @cypress/code-coverage plugin to run Cypress tests and save code coverage reports.
