// Create mock objects for the web.
// --------------------------------
// Our main goal here is to create a Web object which doesn't talk over the internet.
// For this, we need to create a mock IWebRequestHandler.
// This is because Web's constructor expects an IWebRequestHandler. It is 'dependent' on this object.
// However, it's a bit tricky creating a mock IWebRequestHandler. Below is the steps taken to create this mock.
// -----------------------------------------------------------------------------------------------------------
// You can tell mock to return something from an input using Setup().Returns().
// Here I'm telling it, whenever 'ReadStream()' is called, return a known response (the SteamStreamResponse string defined below)
// kept comments for learning purposes ^
// Again, here I want to make a mock IResponse object.
// To make my tests pass, all I want it to do is return a mock stream (defined above).
// Notice I have to call _mockSteamStream.Object. calling '.Object' gets the underlying mocked up object created (the IResponseStream).
_mockResponse = new Mock<IResponse>();
_mockResponse.Setup(x => x.ReadStream()).Returns(SteamStreamResponse);
// Once more, I need one more mock object before testing the Web Class.
// I don't want Web to actually talk over the internet, so I'm creating a mock WebRequestHandler.
// This mock request handler is only set up to return pre-determined values (set up above).
// For example, when given a request of 'HandleWebRequest(Url, Method, null, null, true, "")', it will always return a mock response (defined above)
_mockRequestHandler = new Mock<IWebRequestHandler<IResponse>>();
_mockRequestHandler.Setup(x => x.HandleWebRequest(Url, Method, null, null, true, "", false)).Returns(_mockResponse.Object);
// So, follow this mock structure from bottom to top...
// 1) Mock Web Request Contains a mock response
// 2) Mock Response ontains a Mock Stream.
// 3) Mock Stream will always return 'SteamStreamResponse', i.e. "Response From Stream".
_web = new Web(_mockRequestHandler.Object);
