This patch increases test coverage for pstats.py from 25 to 36%.

It's my first proposed patch so sorry in advance if there are problems. Much more can be done for pstats.py (which is also not much commented) but I want to get some feedback on this first..

[birkenfeld]

I don't understand this comment:
+ #TODO: add more complicated tests, which might almost compile

Also, please don't use docstrings for the test methods because of unittest's "feature" to display them instead of the test method names.

[andreacrotti]

It's really hard to understand true, and if should not go in the patch in general of course.

The sense was that the only test I added is trivial, but I haven't produced something better yet.

And ok I will remove the docstrings, I was actually doing it on purpose thinking about the unittest feature, but if the name is clear enough than is better to leave the docstring out...

Another thing, I didn't want to use tempfile.mktemp to generate a temporary file, but dump_stats doesn't accept anything else, is it in general safe to use it in this case?

@Andrea assuming that you get an answer to the question you posed in msg150292, will you follow up on this?

[andreacrotti]

It has been a long time but if it's still useful sure.

I can see some tests have been added in commit 863b1e4
but if these are still relevant I'm happy to go ahead.

The patch needs to be reviewed. If the tests are still relevant and increase coverage, it needs to be converted to a GitHub PR. Otherwise this issue can be closed.
