The function name test_importing_plugin_always_turns_on_auto_switch_backend doesn't match the updated docstring which states that the plugin "always turns AutoSwitchBackend off". For consistency and clarity, consider renaming the function to test_importing_plugin_always_turns_off_auto_switch_backend to accurately reflect the behavior being tested.

Suggested change

	def test_importing_plugin_always_turns_on_auto_switch_backend():
