When running tests with --optional=sage,optional,external

$ sage -t --show-skipped --optional=sage,optional,external src/sage/graphs/graph_latex.py src/sage/databases/oeis.py src/sage/numerical/mip.pyx src/sage/misc/latex.py

the tests with labels latex,gurobi, graphviz, internet are skipped even if latex,gurobi, graphviz, internet are installed on my machine:

Detecting internetcapabilities is broken: see https://trac.sagemath.org/ticket/25222. To test latex, for example, use these commands: from sage.doctest.external import has_latex and then has_latex(). It should return True.

Also, maybe doctesting is broken: even if software is detected (like latex in your case), maybe it's not used in testing.

has_internet is broken indeed but the other two are not:

sage: from sage.doctest.external import has_internet, has_gurobi, has_latex
sage: has_internet()
False
sage: has_gurobi()
True
sage: has_latex()
True

So there seems to be also a problem in doctesting.

adding has_graphviznow needs review at https://trac.sagemath.org/ticket/25305

And I just figured out that "5 latex tests not run" does not mean they are not run!! https://trac.sagemath.org/ticket/25308 needs review
