推荐答案

如果我们假设您的作业以如此小的间隔运行，以至于您真的希望您的测试等待作业执行而您只想测试作业是否执行被调用，您可以使用以下解决方案:

If we assume that your job runs in such a small intervals that you really want your test to wait for job to be executed and you just want to test if job is invoked you can use following solution:

将 Awaitility 添加到类路径:

<dependency>
    <groupId>org.awaitility</groupId>
    <artifactId>awaitility</artifactId>
    <version>3.1.0</version>
    <scope>test</scope>
</dependency>

编写类似于以下内容的测试:

Write test similar to:

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {

    @SpyBean
    private MyTask myTask;

    @Test
    public void jobRuns() {
        await().atMost(Duration.FIVE_SECONDS)
               .untilAsserted(() -> verify(myTask, times(1)).work());
    }
}
