Mocking HttpWebRequest Accept with Moq

本文关键字:Moq with Accept HttpWebRequest Mocking | 更新日期: 2023-09-27 18:24:02

我正在使用Moq模拟HttpWebRequest。我能够模拟Header&方法,但当我试图嘲笑Accept时,它就爆炸了。

代码为:

 Mock<HttpWebResponse> response = new Mock<HttpWebResponse>(MockBehavior.Loose);
 Mock<HttpWebRequest> request = new Mock<HttpWebRequest>();
 request.Setup(s => s.GetResponse()).Returns(response.Object);
 request.Setup(m => m.Method).Returns("GET");
 request.Setup(h => h.Accept).Returns("application/x-protobuf");

例外情况是:

 System.NotSupportedException was unhandled by user code  
 HResult=-2146233067   Message=Invalid setup on a non-virtual
 (overridable in VB) member: h => h.Accept   Source=Moq   StackTrace:

Mocking HttpWebRequest Accept with Moq

使用Moq无法实现您想要做的事情。Moq不能模拟具体实现的非虚拟方法(使用IInterface也可以)。

,你有几个选择

  1. 创建一个使用HttpWebRequest(例如IHttpClient)实现的简单接口,并在单元测试中使用它
  2. 使用不同的嘲讽框架(看看这篇文章的想法)
