Dear Sage developers,
I have uploaded the conjugacy classes code to the trac server:
trac.sagemath.org/sage_trac/ticket/7886
All the test passed, but the sage -coverage command complained about a
missing testsuite, so I added one (without adding any new test
functions). Much to my surprise, the testsuite fails testing equality:
**********************************************************************
File "/Applications/sage/devel/sage-groups/sage/groups/
conjugacy_classes.py", line 44:
sage: TestSuite(C).run()
Expected nothing
Got:
Failure in _test_eq:
Traceback (most recent call last):
File "/Applications/sage/local/lib/python/site-packages/sage/
misc/sage_unittest.py", line 275, in run

groups/conjugacy_classes.py", line 116, in __cmp__

------------------------------------------------------------
The following tests failed: _test_eq
**********************************************************************
1 items had failures:

***Test Failed*** 1 failures.
For whitespace errors, see the file /Users/javier/.sage//tmp/

----------------------------------------------------------------------
The following tests failed:
sage -t "devel/sage-groups/sage/groups/conjugacy_classes.py"
Total time for all tests: 5.2 seconds
I have no idea what is going on here. I defined a __cmp__ method for
comparing conjugacy classes that essentially just compares the
underlying sets, and the doctest for that function works as expected,
so I don't know what is making the testsuite fail.
Any ideas?
Cheers,
Javier
