Mockito测试失败-实际上，与这个mock没有任何交互

Question

是否有其他方法可以为以下情况编写测试用例，需要为runStudentService方法编写测试用例。尝试写测试用例如下，但它抛出了："；想要但没有被调用——实际上，这个mock没有任何交互">

@Component
public class StudentScheduler {
@Autowired
private StudentService studentService;

@Scheduled(cron = "${cron.students}")
public void runStudentService() {
try {
studentService.startStudetsTest();
} catch (Exception e) {
LOG.error("Error occured during test" + e);
throw(e);
}
}
}
@RunWith(SpringJUnit4ClassRunner.class)
public class StudentSchedulerTest {
@Mock
private StudentService studentService;
StudentScheduler scheduler = Mockito.mock(StudentScheduler.class);

@Test
public void jobRuns() {
Mockito.doNothing().when(scheduler).runStudentService();
verify(scheduler, Mockito.times(1)).runStudentService();
}

}

Answer 1

您的模拟StudentScheduler类没有使用您的模拟studentService实例。仔细检查runStudentService((函数内的实例studentService实例是否与模拟studentService的实例相同。

将模拟的studentService实例传递到要调用的runStudentService((函数中！
