Hi @Balint ! The process-test-coverage extension is not part of Camunda 7 core, which is the scope of Operaton. For additional add-ons we rely on contributors providing the add-ons. We have to focus our resources on the core project ATM.
There is a growing set of such extensions available, which we link on the Operaton Hub page.
Basically, it is pretty easy to adopt any plugin like process-test-coverage:
It is easy to do yourself. If you want someone else to provide it and can sponsor the development & maintenance consider to contact a service provider.
The process-test-coverage will be pretty sure one day in the not too far future available as Operaton compatible version, but the Operaton team can’t tell by whom and when.
