此测试失败，因为我收到CompletionException异常，但是该方法抛出IllegalArgumentException。因此，将实际异常包装到CompletionException中。如何提取包装在CompletionException中的异常？我尝试了异常，处理等，但没有给我我想要的东西。我将异常作为java.util.concurrent.CompletionException：java.lang.IllegalArgumentException：一些消息。
@Test(expectedExceptions = IllegalArgumentException.class, expectedExceptionsMessageRegExp = "some message")
public void someTest() {
CompletableFuture.runAsync(() -> someMethodThrowsException()).join();
}
答案 0 :(得分：2)
这是您为了获得函数抛出的原始异常而可以做的事情：
