我有这些接口
public interface Interface1 { Interface2 Items {get;} }
public interface Interface2 { Guid? ApplicationTypeId { get; } }
public interface Interface3 { Class1 Item {get;} }
public interface Interface4 { Guid? ApplicationId { get; set; } }
一个类继承了第一个接口
public class Class1 : Interface1 {
public Interface2 Items { get; }
}
另一个由几个guid组成的课程
public static class ContentTypeIds
{
public static Guid ContentGuid1 => new Guid("{11798e9d-a167-4cfc-8cfa-9a24fd6caf25}");
public static Guid ContentGuid2 => new Guid("{7d22f5bb-37fd-445a-b322-2fa1b108d260}");
}
我需要对以下属性进行单元测试
private readonly Interface3 _interface3;
public Ticket Current
{
get
{
//This line is very complicated
Interface4 itemByContentType = _interface3.Item?.Items.GetItemByContentType(ContentTypeIds.ContentGuid2);
if ( itemByContentType?.ContentId != null )
return Get(itemByContentType.ContentId.Value);
return null;
}
}
我的测试课程就在这里
[Test]
public class TestClass {
var mock1 = new Mock<Interface1>();
var mock2 = new Mock<Interface2>();
var mock3 = new Mock<Interface3>();
mock1.SetupAllProperties();
mock2.SetupAllProperties();
mock3.SetupAllProperties();
}
'itemByContentType'的值为null。 任何人都可以帮我把它变得简单和可测试,因为测试这个属性变得复杂了吗?我正在使用Moq。我将不胜感激。

答案 0 :(得分:0)
我不是Moq的专家,但看起来它的 SetupAllProperties 方法只是将所有属性设置为属性(即它创建的对象具有可以支持GET的持久成员/ SET操作)。如果没有这样做,那么据我所知,属性仍然可用,但它们将始终解析为<em> null 。这在准备Mock对象时非常方便,但是它本身并没有设置具有任何值的属性。
我认为你应该做的是使用Moq的 SetupGet 和返回方法来准备具有特定值的Items属性的GET。
以下是一些(简化的)示例代码,用于演示:
public interface IFoo { Guid? ApplicationId { get; set; } }
public interface IBar { IFoo Items { get; } }
class Program
{
static void Main(string[] args)
{
// SETUP
// Prepare mocks
Mock<IFoo> MockFoo = new Mock<IFoo>();
Mock<IBar> MockBar = new Mock<IBar>();
// Seting up properties allows us read/write Foo's ApplicationId
MockFoo.SetupAllProperties();
// The mocked Foo object should be what's returned when Items is requested
var expectedFoo = MockFoo.Object;
// Setup the Bar object to return that mocked Foo
MockBar.SetupGet(x => x.Items).Returns(expectedFoo);
// The value written here will be persistent due to SetupAllProperties
expectedFoo.ApplicationId = new Guid("{7d22f5bb-37fd-445a-b322-2fa1b108d260}");
// ACTION
// When the "Items" property is accessed, the IFoo we get should be what we mocked...
var actualFoo = MockBar.Object.Items;
// ... and we can read the value set to Foo's ApplicationId
var actualAppId = actualFoo.ApplicationId;
}
}
