嘲笑SPServer.Local

Question

我希望能夠模擬SPServer.Local返回的對象，但我似乎無法在typemock中執行此操作。在我調試的那一刻，我看到SPServer.Local返回一個SPServer類型的空對象。不應該typemock與我的假實例交換此實例？有什麼我做錯了嗎？代碼在SharePoint服務器上運行良好。

[TestInitialize] 
public void Setup() 
{ 
    fakeSite = Isolate.Fake.Instance<SPSite>(Members.ReturnRecursiveFakes); 
    Isolate.Swap.NextInstance<SPSite>().With(fakeSite); 
    fakeServer = Isolate.Fake.Instance<SPServer>(Members.ReturnRecursiveFakes); 
    Isolate.Swap.NextInstance<SPServer>().With(fakeServer); 
    sharePointStorageRepository = new SharePointStorageRepository(); 
} 


[TestMethod] 
[Isolated] 
public void CreateHRFolderMethodCreatesHRFolder() 
{ 
    // arrange 
    // some arrange logic here 

    // act 
    var actual = sharePointStorageRepository.Create(); 

    // assert 
    Assert.AreEqual(expected, actual); 
} 

這是代碼位的是正在運行：

internal static Guid GetSiteGuid(string serverRelativeUrl, string webApplicationName) 
{ 
    Guid? guid = null; 
    SPServer myServer = SPServer.Local; 
    foreach (var serviceInstance in myServer.ServiceInstances.Where(si => si.Service is SPWebService)){ 
     var service = (SPWebService) serviceInstance.Service; 
     var webapp = service.WebApplications.SingleOrDefault(wa => wa.DisplayName == webApplicationName); 
     if (webapp != null){ 
      var site = webapp.Sites.SingleOrDefault(wa => wa.ServerRelativeUrl == serverRelativeUrl); 
      if (site != null) guid = site.ID; 
     } 
    } 

    if (!guid.HasValue){ 
     throw new FileNotFoundException(
      String.Format(
       "Cannot find Site Collection with WebApplication \"{1}\" and ServerRelativeUrl \"{2}\" running on \"{0}\"", 
       myServer.Address, webApplicationName, serverRelativeUrl)); 
    } 

    return guid.Value; 
} 

謝謝大家！

我不在SharePoint中工作，但我注意到：您實際上並沒有模擬SPServer.Local任何地方的返回。我認爲這是缺失的一步。我也不完全確定你需要SwapNextInstance，因爲我沒有看到任何實際創建SPServer對象的地方。

這將改變你的測試代碼：

[TestInitialize] 
public void Setup() 
{ 
    // I don't see where you're using SPSite, so I assume it's in code 
    // not being shown; otherwise you can remove this. 
    fakeSite = Isolate.Fake.Instance<SPSite>(Members.ReturnRecursiveFakes); 
    Isolate.Swap.NextInstance<SPSite>().With(fakeSite); 
    fakeServer = Isolate.Fake.Instance<SPServer>(Members.ReturnRecursiveFakes); 

    // INSTEAD OF THIS: Isolate.Swap.NextInstance<SPServer>().With(fakeServer); 
    // DO THIS: 
    Isolate.WhenCalled(() => SPServer.Local).WillReturn(fakeServer); 

    sharePointStorageRepository = new SharePointStorageRepository(); 
} 

這WhenCalled方法將意味着任何時候任何人詢問SPServer.Local，它會回報你的假實例。

請注意，我在被測試的代碼中看到您獲得了ServerInstances屬性。我沒有看到任何具體的返回值設置，所以我假設你在省略的「排列」邏輯中控制剩下的東西。
