Subject [Discuss] Feature detection at runtime / test skipping depending on features
Date Thu, 01 Nov 2018 14:29:49 GMT
Hi

There are some tests that fail when some features are not compiled in, such
as Opencv.

In some cases we skip the test according to some precondition such as:

@unittest.skipIf(not graphviz_exists(),....


I would propose that we have a Python module that exports a set of methods
to check what features are compiled in to skip tests which need this
feature.
