Usage - Testing Environment
Installation of jest-puppeteer
# for jest 22~23
yarn add --save-dev [email protected] puppeteer jest
# for jest 24+
yarn add --save-dev jest-puppeteer puppeteer jest
or
# for jest 22~23
npm install --save-dev [email protected] puppeteer jest
# for jest 24+
npm install --save-dev jest-puppeteer puppeteer jest
Update Jest configuration
Create jest.config.js
in the root of your testing environment.
module.exports = {
"preset": "jest-puppeteer"
}
__tests__
folder
Creating To work with default jest-puppeteer
preset, you need to put your test files into the __tests__
folder in the root of your testing environment.
Basic Test Output Code
Following test example in the GIF will generate such code. It starts in my GitHub Profile and clicks one of the pinned repositories (testing-extension) and when page changes it checks for the repository title's href
is https://github.com/omergulen/copycat
or not.
describe('Test 1', () => {
beforeAll(async () => {
await page.goto('https://github.com/omergulen');
});
it('Test 1 - 1', async () => {
await Promise.all([
page.click(':nth-child(2) > .Box > .pinned-item-list-item-content > .d-flex > .text-bold > .repo'),
page.waitForNavigation()
]);
var nodeLink = await page.$$eval('strong > a', el => el[0].href)
expect(nodeLink).toBe('https://github.com/omergulen/copycat');
}, 60000);
});
Update Puppeteer configuration (optional)
Create jest-puppeteer.config.js
in the root of your testing environment.
module.exports = {
launch: {
headless: false, // Disable headless chromium
defaultViewport: null // Set page fit to the browser
},
browserContext: 'default',
}
test
command to the project configuration
Adding In your project's package.json
file, insert "test": "jest"
line into the "scripts"
object.
It will basicly look something like that:
{
"scripts": {
"test": "jest"
},
"devDependencies": {
"jest-puppeteer": "^4.3.0"
},
"dependencies": {
"jest": "^24.8.0",
"puppeteer": "^1.19.0"
}
}
Running tests
yarn run test
or npm run test
will do.
