* Use the same code to profile for test_profile and test_cprofile. * Convert both to unittest. * Use the same unit testing code. * Include the expected output in both test files. * Make it possible to regenerate the expected output by running the file as a script with an '-r' argument.

"""Test suite for the cProfile module."""
Rewrite test_cprofile as unittest (and rename the file to be consistent with all other test files). Written for GHOP by Benjamin Peterson.

The _lsprof module could crash the interpreter if it was given an external timer that did not return a float and a timer was still running when the Profiler object was garbage collected. Fixes issue 3895. Code review by Benjamin Peterson.
