> I invegistate recent CI and find some simple unit test cases take too long
> time to run.
> !image-2021-12-28-17-44-34-272.png!
> I add some logs to watch the unit test and see that when
> EnvironmentUtils.cleanEnv() is called, the MQTTService costs at least 2
> seconds to stop. If there're many cases using @Before and @After to setup and
> teardown environments, it will cost a lot of time. (PhysicalPlanTest has 86
> individual test cases).
>
> The root cause is in the MQTTSinkTest: The setUp() enables the MQTTService in
> the IoTDBDescriptor but the tearDown() doesn't reset it. This causes the all
> following tests enables the MQTTService, as junit is a single process and
> IoTDBDescriptor is a singletion instance.
