from tests.dummydaemon import DummyDaemon
dummy_daemon = DummyDaemon()
def test_start_and_stop_daemon(): daemon = DummyDaemon() start_daemon() assert daemon.is_running() stop_daemon() assert not daemon.is_running()In this example, the `test_start_and_stop_daemon` function uses a `DummyDaemon` instance to test that the `start_daemon` function correctly starts the daemon and the `stop_daemon` function correctly stops the daemon. The `tests.dummydaemon` package library is likely a testing utility package that provides tools and classes for testing daemons and other long-running processes.
