That's how long you lose. Compare it with the time it takes to doctest
control.py (which is not a 'hard' file by any standard)
{{{
(tmp|…)~/sage/doctest$ time sage -tp control.py
...
sage -tp control.py 2.94s user 0.45s system 74% cpu 4.530 total
}}}
And of course this become totally negligible if you test several files, a
folder, or the whole of Sage.

If you are talking about CPLEX and Gurobi, then the time it takes to test
whether they are present is *REALLY* negligible compared to the time it
takes to test for `maple/mathematica/others`. It is more or less
equivalent to load a module and interpret the 'nameerror' if the (cython)
module does not exist. This is done twice, so the cost is very very small.
For the interface.* guys, I personally don't have them on my computer but
I consider the time it takes to run the tests to be non-important. If you
want to use this argument to claim on sage-devel that they should not be
tested, however, you are of course allowed to.
Overall, I think that maple/matlab and others should be included in our
tests, for otherwise they will break forever. Paying `0.5s` in a
`ptestlong` does not stop me. On the other hand I know that it is useless
to argue with you when you do not want to hear something, so I am quite
ready to sacrifice it if you but ask. Just decide something and explain
the outcode to people on sage-devel who would want this to be tested. I
did my part.
