Run interaction tests using event simulation.
Example usage from Blender's source dir:
This uses ``test_undo.py``, running the ``text_editor_simple`` function.
To run all tests:
./tests/python/ui_simulate/run.py --blender=blender.bin --tests '*'
For an editor to follow the tests:
./tests/python/ui_simulate/run.py --blender=blender.bin --tests '*' \
