Third party REST interface mocking, mocking HttpWebRequest and HttpWebResponse

Jay Bishtawi

Hello all, We have a third party component with a REST interface. We have abstracted the calls away in our own methods. I am trying to UNIT test my abstraction layer methods and I am trying to Mock (using Moq) the REST call, but I have not figure out how to do that. Anyone done anything like that before? this is .NET code.

This heavily depends on what your method signatures are but if you want to mock a HttpWebResponse you can use something like this. (This is assuming the code is getting the resposne from a GetResponseStream()) string expectedMessage = "Expected Response"; using (var expectedStream = new MemoryStream(Encoding.UTF8.GetBytes(expectedMessage))) using (var streamReader = new StreamReader(expectedStream)) { Mock

response = new Mock

(); response.Setup(i => i.GetResponseStream()).Returns(expectedStream); var actualStream = response.Object.GetResponseStream(); string actualMessage = streamReader.ReadToEnd(); Assert.AreEqual(expectedStream, actualStream); Assert.AreEqual(expectedMessage, actualMessage); }
