Moving get_ax and do_event to testing

[jakirkham]

I'm wanting to do some testing in a library that uses matplotlib. In particular, this library is using matplotlib native widgets.

There appear to be some utility functions used for testing called get_ax and do_event. These seem like they would be very handy for widget tests like the ones proposed above.

However, I'm not entirely clear on how they can access them ATM as they don't seem to be importable and they are not in testing currently. Would it be possible to move them to testing so they could be used externally? Related would that actually make sense/be usable for my use case?

👍

They are not importable because some packings of mpl strip off the the tests module (there is a lot of binary image data in there).

That's totally reasonable.

Just wanted to make sure I wasn't missing something big w.r.t. using these functions externally. For instance, will I need to have configured an interactive backend to get them to work?

Doesn't look like it.

That docstring is also very wrong...

Yep, it could use some help. 😄

Alright, I've put this on my ToDos. Can't promise I'll get to it soon, but I do plan to come back to it.

lib/matplotlib/testing/widgets.py doesn't exist, so to which file should i move these methods?

@SidharthBansal Please make that file.

I suggest taking the commits in #9905, rebasing them on master, pushing to a branch on your fork and then leaving a note on that 9905 that you have taken over the work.
