Many thanks folks for the review!

I agree with Flavio. @geeksambhu , can we reduce the content of the test_data jsons? It should be enough if they are pod requests, like this one for example, and also containing the relevant part of the pod spec for this policy. So, the spec.containers.securityContext.
