I will get to the tests when I can.

I will get to the tests when I can.

@tomplus I started writing tests, but I noticed that the unit tests for the CustomObjects API are only stubs. There are e2e tests, but there are no e2e tests for CustomObjects (excluding the DynamicClient). Would you like these e2e tests to be added (which would include creating a CRD, creating a custom object of the CRD's type, and then patching the new custom object)?

[tomplus]

Absolutely, it'd be fantastic to have such tests.
