The branch handles this by failing the test (via a CTest property) if
ERROR is in its output.

The idea is to capture expected errors via vtkErrorObserver and verify
that they are the expected error. Anything not expected there or not
caught triggers the CTest property to have it fail on ERROR output. Is
this not the same outcome?
