Errors when testing widget #105

Closed schmiedc closed 2 years ago

schmiedc commented 2 years ago

I played around with testing and went from what was present in the cookiecutter as an example to test widgets. But noticed that I get errors. When applying pytest on a freshly setup cookiecutter I get the following errors:

Thanks for the issue and sorry about that @schmiedc...

I opened https://github.com/napari/cookiecutter-napari-plugin/pull/106 to fix this for future cookiecutter users.
To run tests with pytest locally you'll need to have a couple more dependencies installed. run pip install pytest-qt then try again. If that doesn't do it, let me know

I just experienced the same problem, qtbot is missing when running tests! (with the latest version of the template). Why is pytest-qt not in the testing requirements?

It is ... but only if you said "yes" to "include widget plugin": https://github.com/napari/cookiecutter-napari-plugin/blob/96891d3348d2744dbfd38fb0b140914597fec094/%7B%7Bcookiecutter.plugin_name%7D%7D/setup.cfg#L80

otherwise... there's no immediate need for it, and if you later add a widget manually, then you'll have to add it. (not all plugins need qt, and it's a big thing to add if the plugin isn't using it)

Oh I see, thanks for the explanation!
