Comment #7 on issue 1233 by [email protected]: fix the rest of jython
bugs
http://code.google.com/p/sympy/issues/detail?id=1233
Yes, anything you can report is useful (even better if you manage to fix
it, of
course!). Unfortunately, the test suite doesn't behave properly when sympy
hangs. You
can run only part of the tests by passing a directory to bin/test or by
using the -k
option. For instance, "jython bin/test sympy/core/" will only run the tests
in
sympy/core and "jython bin/test sympy/series/ -k Limits_simple_0" gives the
following:
============================= test process starts

DO *NOT* COMMIT!
So, rather unsurprisingly, there's a problem in the limit code (this is one
of the
most complicated parts of sympy).
