Platform Versions can be tested with the Pimcore integration tests based on k6. These tests have to run through before a new Platform Version is released.
These tests install a Pimcore skeleton and all included Pimcore Extensions based on the version defined by the Platform Version, and then run the k6 tests against them.
The github action can be executed on workflow_dispatch - that means directly in github UI in the actions area.
The Script 00-localsetup.sh allows to execute the tests locally too. When running the script locally, a Pimcore Enterprise Repository token is expected to be the first parameter.
