Discussion:
There are a number of conformance test requirements and guidelines: We should try to automate enforcement to the degree we can, via a "linting" tool, and/or test framework checks. For instance, conformance tests shouldn't invoke framework.ProviderIs or framework.SkipUnlessProviderIs. Those could actually check whether they are invoked by a conformance test, and then die. cc /area conformance
