我想要编写单元测试现有Sitecore的项目上MVC5使用GlassMapperORM和TDS 。我嘲笑了Sitecore内容树，Sitecore上下文，项目属性，字段集合和基本项目，使用Jeff Sulit的这个非常有用的博客文章。无法通过在单位Sitecore的上下文来访问Sitecore的模拟项目（MS正版正货）测试
https://oddeven.ch/blog/mocking-sitecore-using-ms-fakes/
目前已在上述职位的设置（如共享以上链接.... 请通过它去回答之前）。我已将上述设置保存在我的业务层的单独的类文件UnitTestAssist.cs中。
现在我已经写在我从我的单元测试项目创建一个假物品，然后通过Sitecore.Context，Database.GetItem调用，它返回空访问它通过UnitTestAssist类对象的对象以下基本单元测试。
namespace MySiteCoreUnitTest
{
[TestClass]
public class DataFetch
{
IDisposable _context;
readonly MySiteCoreUnitTest.UnitTestAssist _scFaker = new MySiteCoreUnitTest.UnitTestAssist();
[TestInitialize]
public void Initialize()
{
_context = ShimsContext.Create();
_scFaker.Initialize();
}
[TestCleanup]
public void Cleanup()
{
_context.Dispose();
}
[TestMethod]
public void TestingDataFetch()
{
List<ShimField> lstfields = new List<ShimField>();
//Arrange
ShimField dummyField = new ShimField()
{
IDGet =() => ID.NewID,
NameGet =() => "Ava_Title",
ValueGet =() => "This is fucking Crazy"
};
lstfields.Add(dummyField);
var expectedItem = _scFaker.CreateFakeItem(_scFaker.Home, "sample item", (itemName, inputField) => { inputField = lstfields; });
// Act:
var actualItem = Context.Database.GetItem(expectedItem.Instance.Paths.FullPath);
var actualItemFields = actualItem.Fields; // On Debugging i get the field i added forcefully inside **UnitTestAssist**.
// Assert:
Assert.AreEqual(expectedItem, actualItem);
}
}
}
这里是我用来创建模拟物品的代码。
namespace MySiteCoreUnitTest
{
public class UnitTestAssist
{
private readonly Language ContextLanguage = Language.Parse("en");
ShimItem CreateFakeItem(ShimItem parentItem, string name, Action<ShimItem, ShimTemplateItem, List<ShimField>> onItemCreating)

var id = ID.NewID;
var item = new ShimItem()

我已经修改了杰夫的代码能够接受List<ShimField>从单元测试的说法，但它仍然将项目字段为空。杰夫你能帮忙吗？
喜杰夫，我加你需要回答的代码。感谢你的帮助。 –
嗨，Jeff，我正在使用Sitecore 8.1.3。您是否能够使用这段代码成功创建并访问FakeFieldCollection？我必须硬编码UnitTestAssist中的shimfield列表来生成和获取fieldcollection，同时它应该在我提供来自CreateFakeItem方法重载的输入时起作用。 –
嗨尼廷！我注意到你已经添加了两次ShimField：一个在你的faker类和一个在你的单元测试中。你可能想删除faker类中的那个。无论如何，当我尝试从项目中获取字段值时（例如actualItem [“Ava_Title”]），我可以检索该字段的值。你可以改变你的测试，以便这样获得字段值吗？ –
