Comment (by vdelecroix):

 You should not implement `_test_*` method that modifies the object. I am
 not sure there is any control in which order things are executed. It would
 be better in this case to not use the test suite. I would rather have a
 file tests.py that is only made of doctests.

 Moreover, it would make sense to also have comparison between different
 implementations. You can start with
 {{{
 sage: milps = []
 sage: milps.append(MixedIntegerLinearProgram(solver='cplex')  # optional -
 cplex
 sage: milps.append(MixedIntegerLinearProgram(solver='coin')    # optional
 - cbc
 }}}
 and then loop over the elements in milps.
