Input for test_profile.py and test_cprofile.py. | |
IMPORTANT: This stuff is touchy. If you modify anything above the | |
test class you'll have to regenerate the stats by running the two | |
test files. | |
*ALL* NUMBERS in the expected output are relevant. If you change | |
the formatting of pstats, please don't just regenerate the expected | |
output without checking very carefully that not a single number has | |
changed. | |
