quasar might timeout (and not the others) because it is installed with a
lot of optional packages (basically all minus the one that cause
trouble). The relevant optional tests might be, I will test later on
sage: g = graphs.LocalMcLaughlinGraph(); g
Local McLaughlin Graph: Graph on 162 vertices
On at least two tickets I found
TestsFailed 7.5.rc0 Ubuntu/16.04/x86_64/4.4.0-53-generic/quasar
because of timeouts.
At https://trac.sagemath.org/ticket/22064:
sage -t --long src/sage/graphs/generators/smallgraphs.py # Timed out
At https://trac.sagemath.org/ticket/21968:
sage -t --long src/sag
