Third-party components are handled as git submodules which have to be initialized first. So aside from the regular git checkout invoking git submodule update --init or a similar command is needed, for details see Git documentation.

Several apps that are included by default in regular releases such as First run wizard or Activity are missing in master and have to be installed manually by cloning them into the apps subfolder.

Otherwise, git checkouts can be handled the same as release archives, by using the stable* branches. Note they should never be used on production systems.

We use multiple test frameworks for specific areas of the code:

• PHPUnit for PHP unit tests
• Behat for PHP integration tests
• Vitest for Javascript / Typescript unit tests
• Playwright for end-to-end tests

For our end-to-end tests using Playwright you can refer to our documentation on how to debug errors and to contribute new test cases.

• 👀 BrowserStack for cross-browser testing
• 🌊 WAVE for accessibility testing
• 🚨 Lighthouse for testing performance, accessibility, and more

• Comment on a pull request with /update-3rdparty to update the 3rd party submodule. It will update to the last commit of the 3rd party branch named like the PR target.
