@nihalchari Could you please rework the description and write down the classes and files where you want to test. It is better for traceability to see which classes where already touched.

@nihalchari Could you please rework the issue and give more details on what you are currently working and in which classes you intent to work? It is hard to understand where in iceoryx/iceoryx_posh/source/roudi/ you want to write tests.

Additionally the capro tests are missing here.
