求助各位,mock测试中怎么对异步的方法进行mock?

Question

在某个方法中,另起一个线程执行下面的方法,

然后我在mock测试中这么写

但是会报错:Argument(s) are different! Wanted:
threadPoolTaskExecutor.submit(
com.cootf.resim.ocs.test.api.SimResApiTest$$Lambda$34/1389771646@25421809
);
-> at com.cootf.resim.ocs.test.api.SimResApiTest.Should_Return_Flows(SimResApiTest.java:265)
Actual invocation has different arguments:
threadPoolTaskExecutor.submit(
com.cootf.resim.ocs.service.impl.SimResServiceImpl$$Lambda$33/1348937989@714bffd5
);
-> at com.cootf.resim.ocs.service.impl.SimResServiceImpl.returnFlows(SimResServiceImpl.java:257)

小弟刚开始接触mock,求助各位大佬应该怎么写
