验证使用Moq调用的方法

试图验证一个方法是在一个模拟器中被调用,但似乎没有弄清楚为什么我一直得到一个异常抛出它没有被调用。有问题的方法如下:

public class CustomerSyncEngine {
public CustomerSyncEngine(ILoggingProvider loggingProvider, ICrmProvider crmProvider, ICacheProvider cacheProvider) {
  Logger = loggingProvider;
  CrmProvider = crmProvider;
  CacheProvider = cacheProvider;
}
public virtual void SyncPickLists() {
  Logger.LogBeginPicklistSync();

  // get all the pick lists from the local cache
  var localCachePickLists = CacheProvider.GetPickLists().ToList();
  // get all the pick lists from the remote system
  var crmPickLists = CrmProvider.GetPickLists().ToList();

  // build a sync plan
  var changes = BuildPickListUpdatePlan(localCachePickLists, crmPickLists).ToList();

  // run the sync
  RunPickListSync(changes);

  Logger.LogEndPicklistSync();
}
}

然后我写了一个类似的测试:

[TestMethod]
public void TestSyncPickLists() {
  // arrange
  var mockCrm = new Mock<ICrmProvider>();
  mockCrm.Verify(x => x.GetPickLists(), Times.Once(), "ICrmProvider.GetPickLists not called");

  var mockCache = Mock.Of<ICacheProvider>();
  var mockLogger = Mock.Of<ILoggingProvider>();

  // act
  var syncEngine = new CustomerSyncEngine(mockLogger, mockCrm.Object, mockCache);
  syncEngine.SyncPickLists();

  // assert
  mockCrm.VerifyAll();
}

当我运行它时,测试失败并显示我在Verify()中指定的消息。所以我设置了一堆断点,我看到测试从不调用syncEngine.SyncPickLists()方法,这让我很困惑。所以我评论了两个Verify()&amp; VerifyAll()语句,现在我看到正确调用的东西。我在这里错过了什么?看起来我正在完成Quickstart以及this thread所显示的内容。

在调用SyncPickLists之后调用Verify - 它不是延迟的东西,因为它会在那里检查值。将调用下方的行移至SyncPickLists,您应该通过。 - Tejs
