我有一个处理由PullSubscription
Microsoft Exchange 获得的事件的功能。
public void processEvents(ExchangeService service, PullSubscription subscription)
throws Exception {
GetEventsResults events = subscription.getEvents();
// Loop through all item-related events.
for (ItemEvent itemEvent : events.getItemEvents()) {
if (itemEvent.getEventType() == EventType.NewMail) {
EmailMessage message = EmailMessage.bind(service, itemEvent.getItemId());
EmailParser emailParser = new EmailParser();
emailParser.parse(message, service);
}
}
}
我正在尝试使用 PowerMockito 对其进行测试,因为ExchangeService
它是最后一堂课。所以我嘲笑ExchangeService
了PullSubscription
如下:
ExchangeService serviceMock = PowerMockito.mock(ExchangeService.class);
PullSubscription subscriptionMock = PowerMockito.mock(PullSubscription.class);
@Test
public void startPullNotification() throws Exception {
ProcessEmails pr = new ProcessEmails("config.properties");
pr.startPullNotification(serviceMock);
}
当我尝试使用以下代码对其进行测试时,它会抛出一个NullPointerException
因为subscription.getEvents()
返回null
(即其中subscriptionMock
没有事件)。
eventResults
我尝试通过模拟必须返回的来存根它:
when(subscriptionMock.getEvents()).thenReturn(eventResultsMock);
它不起作用,因为getEvents()
在测试函数中没有调用。我想知道如何测试这个功能?

解决方案:
我不得不模拟函数中创建的每个对象。另外,我必须在类声明上方添加以下内容。
@RunWith(PowerMockRunner.class)
@PrepareForTest({ ClassBeingTested.class })
