看起来您正在尝试提出委托而不是事件。是这样吗?
你的代码是这样的吗?
public delegate void FooUpdateDelegate(ref int first, string second);
public class MyClass {
public FooUpdateDelegate FooUpdateDelegate { get; set; }
}
public class MyWrapperClass {
public MyWrapperClass(MyClass myclass) {
myclass.FooUpdateDelegate += HandleFooUpdate;
}
public string Output { get; private set; }
private void HandleFooUpdate(ref int i, string s) {
Output = s;
}
}
如果是这样,那么您可以像这样直接调用 myClass FooUpdateDelegate
[TestMethod]
public void MockingNonStandardDelegate() {
var mockMyClass = new Mock<MyClass>();
var wrapper = new MyWrapperClass(mockMyClass.Object);
int z = 19;
mockMyClass.Object.FooUpdateDelegate(ref z, "ABC");
Assert.AreEqual("ABC", wrapper.Output);
}
编辑:使用界面添加版本
public interface IMyClass
{
FooUpdateDelegate FooUpdateDelegate { get; set; }
}
public class MyClass : IMyClass {
public FooUpdateDelegate FooUpdateDelegate { get; set; }
}
public class MyWrapperClass {
public MyWrapperClass(IMyClass myclass) {
myclass.FooUpdateDelegate += HandleFooUpdate;
}
public string Output { get; private set; }
private void HandleFooUpdate(ref int i, string s) {
Output = s;
}
}
[TestMethod]
public void MockingNonStandardDelegate()
{
var mockMyClass = new Mock<IMyClass>();
// Test fails with a Null Reference exception if we do not set up
// the delegate property.
// Can also use
// mockMyClass.SetupProperty(m => m.FooUpdateDelegate);
mockMyClass.SetupAllProperties();
var wrapper = new MyWrapperClass(mockMyClass.Object);
int z = 19;
mockMyClass.Object.FooUpdateDelegate(ref z, "ABC");
Assert.AreEqual("ABC", wrapper.Output);
}
