I found a way in InSpec to test whether or not python modules have been installed with chef, but I'm using ChefSpec and I can't find an alternative. Does anybody know if there's a way to check if a certain pip module has been installed with ChefSpec?
ChefSpec doesn't test side effects, so you don't check the module itself, you look at what resources were scheduled for execution. If you're using poise-python, that would mean a test like:
it { is_expected.to install_python_package('foo') }
