使用Moq，如何设置带有输入参数的方法调用作为具有预期属性值的对象? [英] Using Moq, how do I set up a method call with an input parameter as an object with expected property values?

问题描述

 var storageManager = new Mock<IStorageManager>(); 
 storageManager.Setup(e => e.Add(It.IsAny<UserMetaData>()));

Add()方法需要一个具有FirstName属性的UserMetaData对象.

The Add() method expects a UserMetaData object which has a FirstName property.

我想确保已传递FirstName为"FirstName1"的UserMetaData类型的对象.

I'd like to make sure that an object of type UserMetaData with the FirstName of "FirstName1" has been passed.

推荐答案

您可以使用Verify.

示例:

验证是否从未使用UserMetaData和FirstName调用Add！= "FirstName1":

Verify that Add was never called with an UserMetaData with FirstName!= "FirstName1":

storageManager.Verify(e => e.Add(It.Is<UserMetaData>(d => d.FirstName!="FirstName1")), Times.Never());

验证带有FirstName == "FirstName1"的UserMetaData至少调用过一次Add:

Verify that Add was called at least once with an UserMetaData with FirstName== "FirstName1":

storageManager.Verify(e => e.Add(It.Is<UserMetaData>(d => d.FirstName=="FirstName1")), Times.AtLeastOnce());

使用FirstName == "Firstname1"和LastName == "LastName2"验证Add刚被调用一次:

Verify that Add was called exactly once with FirstName == "Firstname1" and LastName == "LastName2":

storageManager.Setup(e => e.Add(It.Is<UserMetaData>(data => data.FirstName == "FirstName1"
                                                         && data.LastName  == "LastName2")));

...

storageManager.VerifyAll();
