[TIP] Use unittests for profiling?

[Matthew Wilson]

I've been writing lots of snippets of code and then feeding them into
cProfile and timeit, looking for stuff to optimize.  It dawned on me
recently that these snippets look a lot like some of my unittest
classes: each snippet has a few statements and an optional setup
block.  In both cases, I'm isolating a component from a bigger system
and then running just that component.

Has anyone done any work to reuse unit tests for profiling and timing?

Is there something theoretically wrong with this idea?

There's a practical hurdle -- the cProfile and timeit modules were
originally designed to eat strings of code.  They can work with
callable objects, but I am finding that to be a little difficult when
I have non-trivial setups.
