我有一个异步回调，我为此编写了一个 junit 测试用例。我正在遵循 CountDownLatch 方法。如果回调失败，我必须使测试用例失败。这是我的代码
lock = new CountDownLatch(buildId.size());
DockerBuildController controller = context.getBean(DockerBuildController.class);
BuildService actualService = (BuildService) ReflectionTestUtils.getField(controller, "buildService");
BuildService service = Mockito.mock(BuildService.class);
ReflectionTestUtils.setField(controller, "buildService", service);
Mockito.doAnswer(new Answer<Void>() {
public Void answer(InvocationOnMock invocation) throws GitAPIException, IOException {
Object[] args = invocation.getArguments();
System.out.println("called with arguments: " + Arrays.toString(args));
actualService.dockerBuildCallback(args[0].toString(), args[1].toString(), args[2].toString(),
args[3].toString(), args[4].toString());
if (args[2].equals("success")) {
lock.countDown();
} else {
try {
Assert.assertTrue(buildId.contains(args[0]) && args[2].equals("success"));
} catch (AssertionError e) {
actualService.dockerBuildCallback(args[0].toString(), args[1].toString(), "success",
args[3].toString(), args[4].toString());
lock.countDown();
fail(args[0] + " failed.");
}
}
return null;
}
}).when(service).dockerBuildCallback(Mockito.anyString(), Mockito.anyString(), Mockito.anyString(),
Mockito.anyString(), Mockito.anyString());
try {
lock.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
我doAnswer发现我想让测试用例失败。它抛出以下 AssertionError 但在测试报告中显示测试用例绿色。
java.lang.AssertionError: 2e58e41c-e4a9-4a71-909e-4b7cb822af9c failed.

我的要求是将此测试显示为红色。
最佳答案
按照Arrange->Act->Assert单元测试结构，在Arrange阶段不应该有任何断言(除非它是一个守卫断言，而你的断言不是)。
doAnswer 功能接口(interface)是单元测试的Arrange 阶段的一部分。
也可能是 Mockito 由于某种原因吞下了该断言异常。
尽量不要在 doAnswer 内断言，而是设置某种标志，并在 Assert 阶段进行检查:
this.success = buildId.contains(args[0]) && args[2].equals("success");
...
// Assert
assertThat(this.success).isTrue();
关于java - Async AssertionError 未使测试用例失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56521214/
