Running tests only with the optional packages (not the external packages),
I managed to complete the doctests of the whole library. I get:
----------------------------------------------------------------------
sage -t --long --random-seed=0
src/sage/combinat/designs/incidence_structures.py # 1 doctest failed
sage -t --long --random-seed=0 src/sage/graphs/generic_graph.py # 2
doctests failed
sage -t --long --random-seed=0 src/sage/graphs/graph.py # 3 doctests failed
sage -t --long --random-seed=0 src/sage/interfaces/singular.py # Killed
due to segmentation fault
----------------------------------------------------------------------
rerunning failed tests, I get:
----------------------------------------------------------------------
sage -t --long --random-seed=0
src/sage/combinat/designs/incidence_structures.py # 1 doctest failed
sage -t --long --random-seed=0 src/sage/graphs/generic_graph.py # 2
doctests failed
sage -t --long --random-seed=0 src/sage/graphs/graph.py # 3 doctests failed
