Unit test for several bpmn files

Hello everybody,
I am new to Camunda, and I have to create some unit testing for several bpnm files to run into a CI/CD.
All this files will be together in the same path in the classpath, but their name and content are unknown.
I need to create a dynamic unit testing to check that the files are correct and there are no issues in them.
My question is how can I retrieve the files, ids and so, without knowing their name and content; how can read them? how can I get them? and how can I see their content.

I tried with @Deployment annotation in the test class, but from here, how can I have the files, or iterate over them to run the test cases? how can I know if @Deployment has got these files?

I am working under java 21 and SpringBoot
Thank you in advance, any tip is welcome!
