e2e-tests implementation for Yoast SEO plugin.

To run the tests locally, do the folowing:

1. Start by cloning this repository: git clone https://github.com/Yoast/wordpress-seo.git.
2. Then move to the repository folder cd wordpress-seo.
3. Checkout the e2e-tests branch by doing git checkout try/e2e-tests-package.
4. To install all the necessary dependencies, run the following commands:

There are some conflicts that could happen with Puppeteer and newer versions of Node. Before running the following commands, please make sure your Node version is set to 12. This can be done through nvm, with the command nvm use 12.

composer install
yarn
grunt build:dev

5. Move to the package folder by doing cd packages/e2e-tests.
6. Now you will need to start a WordPress local environment using @wordpress/env.

First make sure Docker is running on your machine and run this command bash e2e-test-env-setup.sh. The command will execute the e2e-test-env-setup.sh file. This file basically:

• Move to the plugin root folder
• Start the WordPress local environment
• Install and activate the yoast-simple-custom-post-type.zip plugin: the plugin creates a custom post type used in the tests

7. Run the command yarn test:e2e to run the tests.
8. When you are done with testing, run the following commands:

cd ../..
wp-env stop

that stop the local environment.

A configuration example is present in the jest-puppeteer.config.js.example file.

The default configuration of the packages runs the test in headless mode. If you want to run the tests in headless mode, rename the jest-puppeteer.config.js.example file to jest-puppeteer.config.js

Slow Motion slows down Puppeteer operations by a specified amount of milliseconds. Comment the slowMo: 100, line in jest.puppeteer.config.js to disable it. You can also edit the slowMo value to change its behaviour.
