Plot tests
In some recent commits there was a _test_fig_handles
argument added to the plotter. I think this would be better to avoid hidden arguments in public methods like this, since they can cause trouble such as suppressing too-many-argument errors. Maybe we should just change the argument to figures
, make it optional, and if users want to use it they can?
This can probably also be tested via pytest monkeypatching but probably in a more convoluted way than changing the name of the argument.
