Support kernprof -m module #29
Description
Sometimes I wish to profile a unit test. To do this I have to do
kernprof -l $(which pytest) path/to/testfile.py::test_that_I_want
It would be nice if kernprof allowed me to run a Python module rather than a script with
kernprof -l -m pytest path/to/testfile.py::test_that_I_want
This is what Python itself (python -m ...) and some related tools like coverage run -m ... allow.

Is this supported yet?

It's a good idea. I'll support a PR adding the
-margument to kernprof.However, the new docs outline a new alternative that is often easier than using kernprof. As of 4.1.x you can now just
from line_profiler import profileand by default the decorator does nothing. But if you set the environment variableLINE_PROFILE=1or pass a--line-profileon sys.argv theprofiledecorators will enable and dump a profile of your code at the end of running. This is how I test my modules when I usepython -m.You can also enable it programatically: e.g.
and
profilehas a configuration dictionary you can use to modify behavior. I'd also accept PRs if this config doesn't have everything necessary.
