Currently, the SimpleTestResourceWrapper uses with self._debugging_output.capture_stdout_and_stderr() to capture stdout and stderr with no way to disable it. This prevents using pdb for test debugging because it's unable to pipe stdout/stderr. I have manually patched my sources by adding a capture: bool = False option in each of the resource hook functions, but it would be nice to have it supported with your intentional design input.

I could also fork and submit a PR, if needed.
