Wix-ui-mocha-runner NPM

wix-ui-mocha-runner

Run unit tests in headless Chromium using Mocha and Puppeteer.

The package provides wix-ui-mocha-runner CLI program which needs to run in the project root. It looks for test files that match *.spec.ts?(x) pattern in the src folder. The test results are logged to the terminal. All browser console output is redirected to the terminal as well.

To run tests interactively in watch mode with hot reload start wix-ui-mocha-runner --watch, and open http//127.0.0.1:7357. You can click the play icon to the right of the test name or a group of tests to run only a subset of tests. If the test page starts to constantly refresh make sure it's not open in mutliple tabs.

The tool performs the following setup for you:

Configures Mocha with "BDD"-style interface
Configures Enzyme with enzyme-adapter-react-16 adapter
Exposes expect assertion library as a global variable
Adds a level of compatibility with tests written for Jest:
- Exposes jest-mock as a global named jest, which allows to use jest.fn()
- Adds an alias beforeAll() for before()
- Adds an alias afterAll() for after()
Adds a test reporter for TeamCity
