The primary goal of the ptests is integration testing so if we’re having to manually install and run the tests then it’s entirely reasonable if not desirable to pick a subset of the tests.

In this case, we don’t need to run the fuzzer tests and so on.  I’d suggest maybe just fullbench and cli-tests would be sufficient here, less to install and faster execution.
