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.
