[QUESTION] Testing apps in parallel

Implementing a test context would be more preferable since testing with a real instance is impossible with multiple test workers: I have two of ten test runs failed due to messages being consumed by another test worker and I have no idea how to deal with it but declare separate topics for test purposes only. So how do I test my apps in parallel? Having a test context would be really good since there would not be any need in creating topics and posting messages to them neither on CI nor on my local machine
