# No, TimeoutDLIPowerSwitch is defined at module load time.

# No, imports happen at top level.
# If power-switch-pro is missing, RealDLIPowerSwitch is the dummy class.

# So we can't easily instantiate TimeoutDLIPowerSwitch in the test if the lib is missing.
# However, we can MonkeyPatch server.RealDLIPowerSwitch to allow instantiation?

# Workaround: Dynamically create a class with the same logic for testing purposes,
# OR mock the session on the instance after creation if possible (but init raises error).
# Let's mock server.RealDLIPowerSwitch completely by replacing the class in the module
