Java 使用testng测试forkjoinpool

我想编写一些测试，用ForkJoinPool检查对rest服务的异步调用。我有以下代码：

final ForkJoinTask<List<Something>> someJoinTask1 = new RecursiveTaskLambda<>(
                () -> service1.findAll(filter));
this.forkJoinPool.execute(someJoinTask);
final ForkJoinTask<List<Something>> someJoinTask2 = new RecursiveTaskLambda<>(
                () -> service2.findAll(filter));
this.forkJoinPool.execute(someJoinTask);
// some stuff happening here
try {
    firstList= someJoinTask1.get();
    secondList = someJoinTask2.get();
}
catch (final InterruptedException | ExecutionException e) {
     throw new MyException("Couldn't load mandatory data for screen", e);
}
getView().setSomething1(firstList);
getView().setSomething2(secondList);

//prepare some stuff for the test   
Mockito.when(this.service1.findAll(Matchers.any(MyFilter.class))).thenReturn(someStuff);                
// ----Call tested method----
someMethod();        
Mockito.verify(this.view).setSomething1(captor.capture());
Mockito.verify(this.view).setSomething2(captor.capture());
// ----Asserts----

问题是，当我执行测试时，它会永远运行。我试图添加Thread.sleep（）只是想看看这是否会改变，但没有改变。当我尝试调试测试时，它会通过所有准备代码调用测试方法，当它到达

firstList=someJoinTask1.get（）时在
someMethod（）中它挂起

这是我的线程转储（我不知道是否需要）：

我正在使用TestNg和Mockito
