How do I test Python programs with signal handlers (e.g., SIGUSR1, SIGINT, etc.)?

Running signal-based unit tests makes the GitHub Actions to hang or terminate prematurely.
The test suite works perfectly fine on local environments, specifically, when executed from a shell prompt.
Is there any way to let my test suite to run as a separate process group or session, so that intentionally raised signals are delivered to only the test program, not the action runner?

@achimnol,

On GitHub Actions workflow, we seem have no available easy methods to do that. There are not any actions for signal-based unit tests can be found on the GitHub Marketplace.

Maybe there’s a different way to test signal handling?
