End-To-End (E2E) tests for WordPress.

The e2e tests require a production-like environment to run. By default, they will assume an environment is available at http://localhost:8889, with username=admin and password=password.

If you don't already have an environment ready, you can set one up by following these instructions.

Then you can launch the tests by running:

npm run test:e2e

which will run the test suite using a headless browser.

If your environment has a different url, username or password to the default, you can provide the base URL, username and password like this:

npm run test:e2e -- --wordpress-base-url=http://mycustomurl --wordpress-username=username --wordpress-password=password

DO NOT run these tests in an actual production environment, as they will delete all your content.

For debugging purposes, you might want to follow the test visually. You can do so by running the tests in an interactive mode.

npm run test:e2e -- --puppeteer-interactive

You can also run a single test file separately:

npm run test:e2e tests/e2e/specs/hello.test.js
