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 devThis instance of create-react-app has been enhanced with the following testing libraries:
| Library | Description |
|---|---|
| Jest | Automated testing |
| Enzyme | Unit test React components in isolation via shallow or with children via mount |
| enzyme-adapter-react-16 | Configures enzyme to work with React 16 |
| react-test-renderer | Render React components to JSON for snapshot testing |
| redux-mock-store | Mock store for testing your redux async action creators and middleware |
| Cypress | In browser integration testing via Mocha and Chai |
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-craLoad 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.
