I just want to point out that you could use gdb python for debugging.

just run gdb python and then "run path/file.py". At least it works for
me and doesn't need this import os stuff and looking up PIDs.

This works in most cases (and is how I usually debug GNU Radio apps written in Python.)

However, in the case of the QA code, the 'make test' command executes the Python script with a very specific set of environment variables to allow the QA code to find GNU Radio as part of the build tree, not the system installation, so the technique Tom outlined is needed to attach gdb after all that takes place.
