too many patch in test

there are sooo many patch in the unit test / integration test, I think it's not good.

@dosu any idea?

The issue names unit and integration tests but provides no files or failing case. Start by locating the tests that use patch and establish which usage is considered unnecessary, then confirm the scope and completion criteria with maintainers. Done is an agreed, tested reduction in unnecessary patching.
