Hello Ricardo, python-graphviz does not pass its tests any more in core-updates, and I can trace it back to your commit 3d388fe3d0475f2e991ae061cc1364529a97af42. Adding python-mock back to native-inputs fixes it.
Or maybe python-pytest-mock should have python-mock as propagated input? It calls itself a "Thin-wrapper around the mock package for easier use with py.test", but does not even have python-mock as any kind of input. Thanks for your help, Andreas
