Puppeteer & Jest

Jest-Puppeteer allows you to run tests with Jest on browsers controlled with Puppeteer.

To get started, please install these packages:

Copy code
npm install --save-dev jest-puppeteer puppeteer jest

Next, specify these settings in your Jest configuration file (jest.config.js):

Copy code
module.exports = {
  rootDir: '.',
  testTimeout: 20000,
  testMatch: [
    '<rootDir>/*.spec.js'
  ],
  preset: 'jest-puppeteer'
}

Configure Jest with Puppeteer

To configure Jest Puppeteer, create a new file called jest-puppeteer.config.js and add this to the file:

Copy code
module.exports = {
  connect: {
    browserWSEndpoint: 'wss://cloud.testingbot.com?key=api_key&secret=api_secret&browserName=chrome&browserVersion=latest'
  }
}

This instructs Jest and Puppeteer to connect to the TestingBot browser grid.

Specifying browser and version

To specify on which browser and version your Jest + Puppeteer test should run, you can include both a browserName and browserVersion in the browserWSEndpoint URL.

Select a browser & version
Copy code

Run your first test

To create a test, create a new file called sample.spec.js and add this to the file:

Copy code
describe('Google', () => {
  beforeAll(async () => {
    await page.goto('https://google.com')
  })

  it('should display google text on page', async () => {
    await expect(page).toMatch('google')
  })
})

Now you can run your first test with Puppeteer on the TestingBot cloud:

Copy code
$ jest

This will open Google in a Chrome browser and verify if the word 'google' is on the page.

You should see something like this in your terminal after running the command:

Copy code
PASS  ./sample.spec.js (6.503s)
  Google
    ✓ should display google text on page (81ms)
