How to run pytests

[whs92]

I have been trying to make some changes to a fork of this repository, I would like to test those changes. I had a go at running the pytests included in models/_tests but I couldn't run any of them, even on the master branch.

Can you give me some pointers? I don't know what this means

file /home/emil/bluesky/gui/bluesky-widgets/bluesky_widgets/models/_tests/test_rastered_image.py, line 29
  def test_rastered_image(non_snaking_run, FigureView):
E       fixture 'qtbot' not found

>       use 'pytest --fixtures [testpath]' for help on them.
