--------------------------------------------------------------------
The rootcause of this failure is that we run a Python 3-only test in Python 2.
To be excluded from execution on Python 2, test needs to end with _py3, not
_py37. However, this may not be sufficient for the purposes of the failing test
in case if it uses py37 syntax that is invalid on Python 35 (we can check if it
also fails in Python 3.5 postcommits). If so, this is may be the first such
test, as we don't have a per-minor version exclusion mechanism yet.
We could improve the rules of how py3 tests are excluded, or, perhaps wait
until we switch to py_test, which may make these type of configurations easier.
