Test unitario in asp.net MVC, come faccio a prendere in giro una richiesta di pagina?

Question

Come faccio a prendere in giro una richiesta di pagina per una pagina .net MVC?

Answer 1

Uso RhinoMocks:

var httpContext = MockRepository.GenerateMock<HttpContextBase>(); 
var httpRequest = MockRepository.GenerateMock<HttpRequestBase>(); 

httpContext.Expect(c => c.Request).Return(httpRequest).Repeat.Any(); 

... set up expectations on request... 

var controller = new MyController(); 
controller.ControllerContext = new ControllerContext(httpContext, 
                 new RouteData(), 
                 controller); 

...invoke action, check assertions... 

httpContext.VerifyAllExpectations(); 
httpRequest.VerifyAllExpectations(); 

Answer 2

Uso Moq:

var request = new Mock<HttpRequestBase>(MockBehavior.Strict); 
request.Setup(x => x.ApplicationPath).Returns("/"); 
request.Setup(x => x.Url).Returns(new Uri("http://localhost/home")); 
request.Setup(x => x.ServerVariables).Returns(new System.Collections.Specialized.NameValueCollection()); 

var context = new Mock<HttpContextBase>(MockBehavior.Strict); 
context.SetupGet(x => x.Request).Returns(request.Object); 

var controller = new YourController(); 
controller.ControllerContext = new ControllerContext(context.Object, new RouteData(), controller); 

Answer 3

manualmente (perché odio derisione quadri che richiedono 8 righe di configurazione per prova)

// in some common location, only once 
public class MockHttpContext : HttpContextBase 
{ 
    public MockHttpRequest m_request = new MockHttpRequest(); 
    public MockHttpResponse m_response = new MockHttpResponse(); 

    public override HttpRequestBase Request 
    { get { return m_request; } } 

    public override HttpResponseBase Response 
    { get { return m_response; } } 
} 

public class MockHttpRequest : HttpRequestBase 
{ 
    // override whatever bits you want (eg cookies) 
} 

public class MockHttpResponse : HttpResponseBase 
{ 
    // override whatever bits you want (eg cookies) 
} 

// in your specific test 
controller = new YourController { 
    ControllerContext = new ControllerContext { HttpContext = new MockHttpContext() } 
};
