This repo contains an example implementation of the abstract AMP E2E Functional Test API.

To run, try the package.json scripts

yarn
./install-drivers.sh

yarn run test-amp
yarn run test-expect
yarn run test-github
yarn run test-hello
yarn run test-iframe

You can also run tests using:

yarn run test spec/test-amp.js

To run a specific test case, you can use Mocha's grep functionality to find test cases matching a regex. For example:

yarn run test spec/test-amp.js -g "scroll"

Tests can be written with mocha style structure, and using the API methods from the FunctionalTestController API.

import * as describes from '../lib/describes';
import {expect} from '../lib/expect';

describes.endtoend('First test', {
    engines: ['puppeteer'],
}, async env => {
  let controller;

  beforeEach(async () => {
    controller = env.controller;
    await controller.navigateTo('https://www.google.com');
  });

  it('should expect hello to not equal world', async () => {
    await expect('hello').to.not.equal('world');
  });
});

Tests can be debugged using the Chrome debugger. Run the test command and pass the --inspect-brk flag. Then open Chrome DevTools and click the Node icon. This will allow you to step through the code. The DevTools breakpoints can sometimes not trigger, but debugger statements in test code or component code are a dependable way to interrupt control flow.
