If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception *might* occur in wrongly written multi-threaded tests.
   Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies - 
   - with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.

试着重写这部分

CompletableFuture<List<HDTreatmentOrder>> hdFuture = spy(CompletableFuture.completedFuture(Collections.emptyList()));
when(hdFuture.get()).thenThrow(new InterruptedException())

作为

doThrow(InterruptedException.class).when(hdFuture).get();

其他间谍也一样：

CompletableFuture<List<PDTreatmentOrder>> pdFuture = spy(CompletableFuture.completedFuture(Collections.emptyList()));
when(pdFuture.get()).thenThrow(new InterruptedException());

作为

doThrow(InterruptedException.class).when(pdFuture).get();

当像那样监视CompletableFuture时，他们似乎并不认为CompletableFuture.join() "完成"了。
我认为您应该使用以下代码：

when(hdService.getData(any(), any())).thenReturn(CompletableFuture.failedFuture(new InterruptedException()));
when(pdService.getData(any(), any())).thenReturn(CompletableFuture.failedFuture(new InterruptedException()));

也不需要hdFuture和pdFuture间谍。
TreatmentOrderService中的异常处理可能需要修复，但测试完成而不是挂起。

实际上，可能不需要CompletableFuture.join()，因为您正在下一行执行.get()，线程将在该点阻塞，直到future以某种方式完成。
只需删除CompletableFuture.allOf(...).join()行（以及@pzelenovic建议的修改），即可使测试通过（不必要的存根除外...）。
