是否可以在Moq中传递参数值？

Question

我需要以HttpResponseBase.ApplyAppPathModifier这样的方式进行模拟,即ApplyAppPathModifier模拟自动返回调用参数.

我有以下代码:

var httpResponseBase = new Mock<HttpResponseBase>();
httpResponseBase.Setup(hrb => hrb.ApplyAppPathModifier(/*capture this param*/))
                .Returns(/*return it here*/);

有任何想法吗？

编辑:

在Moq文档的第一页(http://code.google.com/p/moq/wiki/QuickStart)上找到了解决方案:

var httpResponseBase = new Mock<HttpResponseBase>();
httpResponseBase.Setup(hrb => hrb.ApplyAppPathModifier(It.IsAny<string>)
                .Returns((string value) => value);

我突然觉得很愚蠢,但我想这就是你在23:30写代码时会发生什么

Answer 1

是的,您可以回显传递给该方法的参数

httpResponseBase.Setup(x => x.ApplyAppPathModifier(It.IsAny<string>()))
                .Returns((string path) => path);

如果需要,您也可以捕获它

string capturedModifier = null;

httpResponseBase.Setup(x => x.ApplyAppPathModifier(It.IsAny<string>()))
                .Callback((string path) => capturedModifier = path);

Answer 2

用途It:

It.Is<MyClass>(mc=>mc == myValue)

在这里,您可以检查期望:您希望收到的价值.在回报方面,只需返回您需要的价值.

var tempS = string.Empty;
var httpResponseBase = new Mock<HttpResponseBase>();
httpResponseBase.Setup(hrb => hrb.ApplyAppPathModifier(It.Is<String>(s=>{
           tempS = s;
           return s == "value I expect";
           })))
                .Returns(tempS);
