Nothing ran the full test suite on a pull request. The only check was the structure of the translations, so a change that breaks a test reaches quattro unseen. A change merged into quattro runs the suite on every pull request and on every push to quattro.

The check boots a virtual machine of the current stable image and runs the suite in the desktop session, as the logged-in user, with the session kept awake. The notes record that on the same commit, that suite in a container skipped checks in 64 of 404 files. In the virtual machine, seven files skip, for hardware the virtual machine does not have.
