Guide about how to extend the Test Engine (specifically the container life cycle)

[aberg09]

I want to use property-based testing (PBT) for our Quarkus project and have not found a PBT library that can integrate with the Quarkus Test engine (if I have overlooked something, please correct me). I therefore want to write an own PBT-extension for Quarkus.

In order to do that I need to understand the internals of Quarkus Test Engine better. Is there are guide or dev documentation for that?

Specifically my problem is that my classes do not get injected automatically into the PBT engine. The PBT library (I am trying jqwik) provides hooks that can bring both engines together, i.e. I know how to transfer information to the PBT engine. What I do not understand is where to find the information (container management, something like a test context or an equivalent to Spring's TestContextManager class) within the Quarkus test engine.

Any hint is welcome.
