I don't have much understanding of Leo's tests myself. I think that your
case 1 would be handled by opening a NullGui. This will give you a working
g, from which you can access a lot of Leo's functionality. I'm not sure
how to deal with getting a commander with a null gui. But there must be
some test in Leo's source tree that could be a model.
For example, in leo/unittests/core, I see a file *test_leoColorizer.py*. It
has a class *TestColorizer(LeoUnitTest)*, which includes:
from leo.core import leoGlobals as g
from leo.core.leoTest2 import LeoUnitTest
from leo.core.leoQt import Qt
import leo.core.leoColorizer as leoColorizer
# ...
"""Test cases for leoColorizer.py"""
def color(self, language_name, text):
"""Run the test by colorizing a node with the given text."""
c = self.c
c.p.b = text.replace('> >', '>>').replace('< <', '<<')
c.recolor_now()
Looking in LeoPyRef for the base class *LeoUnitTest,* I find it in
*leoTest2.py*. When I run py -m pytest in Leo's top directory, it runs all
these many tests but does I never see a visible Leo window. So in those
unit test files are all the techniques to do what you want.
