Unittest presents only total time spent on running all tests but does not present time spent on each test separately.
How to add timing of each test when using unittest?
unittest now supports this natively (to the millisecond) with the --durations 0 option.
$ python -m unittest Lib.test.test_ftplib --durations 0
