For some reason in the scene properties context.object returns None even if an object is active in the viewport, so ifc modifiers would randomly throw errors. AFAIK functionally they are supposed to point to the same thing, but active_object seems to be the superior one and context.object deprecated and kept for legacy reasons. Couldn't find dev quote but I'm sure I saw it at some point
Taking into account that now we have error messages if user will try to remove the last material layer which would make layer set invalid ifc.
FAILED test/bim/test_feature.py::test_remove_material_set_layer - AssertionError: Failed to run operator bpy.ops.bim.remove_layer(layer=IfcStore.get_file().by_id(93).MaterialLayers[...
FAILED test/bim/test_feature.py::test_export_ifc__with_basic_contents_and_saving_as_a_relative_path - AssertionError: Value is C:\IfcOpenShell\src\blenderbim\test\files\temp\export.ifc
Can be easily called with `pytest .\test\bim\test_feature.py -k "issue"`
Commented some lines out to make sure it doesn't interrupt someone's test process.
Need to uncomment `When I press "bim.create_drawing"` if you want to see if it freezes for you.
You can also uncomment `And I save sample test files and open in blender` to see the freeze manually in Blender client.
Created some simple undo tests.
This "flip wall and ctrl-z" test actually is crashing blender if I do it manually - so I guess undo in background mode is still kind of different.
`sequence.feature` - Added `[:]` to make errors more readable values in errors (for example, (0.20000000298023224, 0.20000000298023224, 0.20000000298023224, 1.0) instead of `<bpy_float[4], Object.color>`
`test_feature.py` - fixed `FAILED test/bim/test_feature.py::test_animate_the_consumption_of_a_wall - AssertionError: Value is <bpy_float[4], Object.color>`
Test was failing because of float garbage in object.color (the comparison was (0.20000000298023224, 0.20000000298023224, 0.20000000298023224, 1.0) <> [0.2, 0.2, 0.2, 1] )
After that fix all tests now are passed 🥲
