[TIP] How would you test something that deals with processes?

Mocking is nice and easy for this, and it's important to have some
unit-tests for this one.
I would personally add an integration test, that runs a real process,
because you usually want to test that your interface to the OS is correct as
The best process to run is some kind of python or shell script that you can
predict its behavior. For instance a C process that allocates a certain
amount of memory each 10 seconds, etc.
You can also catch the kill signal and have the process print some kind of
error to stderr if it thinks it caught the signal at the wrong time, etc.
This way you can predict how your process behaves and when it should be
killed, and test for it.
