如何使用 Moq 模拟 ASP.NET MVC 中的 HttpContext？

[TestMethod]
public void Home_Message_Display_Unknown_User_when_coockie_does_not_exist()
{
    var context = new Mock<HttpContextBase>();
    var request = new Mock<HttpRequestBase>();
    context
        .Setup(c => c.Request)
        .Returns(request.Object);
    HomeController controller = new HomeController();

    controller.HttpContext = context; //Here I am getting an error (read only).
    ...
 }

我的基本控制器覆盖了获取此 requestContext 的初始化。我正在努力传递这一点，但我没有做正确的事情。

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    base.Initialize(requestContext);
}

在哪里可以获得有关使用 Moq 模拟 RequestContext 和 HttpContext 的更多信息？我正在尝试模拟 cookie 和一般上下文。

[TestMethod]
public void Home_Message_Display_Unknown_User_when_coockie_does_not_exist()
{
    var context = new Mock<HttpContextBase>();
    var request = new Mock<HttpRequestBase>();
    context
        .Setup(c => c.Request)
        .Returns(request.Object);
    HomeController controller = new HomeController();

    controller.HttpContext = context; //Here I am getting an error (read only).
    ...
 }

my base controller has an overrride of the Initialize that get's this requestContext. I am trying to pass this along but I am not doing something right.

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    base.Initialize(requestContext);
}

Where can I get more information on mocking my RequestContext and HttpContext using Moq? I am trying to mock cookies and the general context.

HttpContext 是只读的，但它实际上是从 ControllerContext 派生的，您可以对其进行设置。

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

HttpContext is read-only, but it is actually derived from the ControllerContext, which you can set.

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

创建请求、响应并将它们都放入 HttpContext：

HttpRequest httpRequest = new HttpRequest("", "http://mySomething/", "");
StringWriter stringWriter = new StringWriter();
HttpResponse httpResponse = new HttpResponse(stringWriter);
HttpContext httpContextMock = new HttpContext(httpRequest, httpResponse);

Create a request, response and put them both to HttpContext:

HttpRequest httpRequest = new HttpRequest("", "http://mySomething/", "");
StringWriter stringWriter = new StringWriter();
HttpResponse httpResponse = new HttpResponse(stringWriter);
HttpContext httpContextMock = new HttpContext(httpRequest, httpResponse);

感谢用户 0100110010101。

它对我有用，在这里我在为以下代码编写测试用例时遇到了问题：

 var currentUrl = Request.Url.AbsoluteUri;

这是解决问题的行

HomeController controller = new HomeController();
//Mock Request.Url.AbsoluteUri 
HttpRequest httpRequest = new HttpRequest("", "http://mySomething", "");
StringWriter stringWriter = new StringWriter();
HttpResponse httpResponse = new HttpResponse(stringWriter);
HttpContext httpContextMock = new HttpContext(httpRequest, httpResponse);
controller.ControllerContext = new ControllerContext(new HttpContextWrapper(httpContextMock), new RouteData(), controller);

可能对其他人有帮助。

Thanks user 0100110010101.

It worked for me and here i had an issue while writing the testcase for the below code :

 var currentUrl = Request.Url.AbsoluteUri;

And here is the lines which solved the problem

HomeController controller = new HomeController();
//Mock Request.Url.AbsoluteUri 
HttpRequest httpRequest = new HttpRequest("", "http://mySomething", "");
StringWriter stringWriter = new StringWriter();
HttpResponse httpResponse = new HttpResponse(stringWriter);
HttpContext httpContextMock = new HttpContext(httpRequest, httpResponse);
controller.ControllerContext = new ControllerContext(new HttpContextWrapper(httpContextMock), new RouteData(), controller);

Might be helpful for the others.

以下是我如何使用 ControllerContext 传递假应用程序路径：

[TestClass]
public class ClassTest
{
    private Mock<ControllerContext> mockControllerContext;
    private HomeController sut;

    [TestInitialize]
    public void TestInitialize()
    {
        mockControllerContext = new Mock<ControllerContext>();
        sut = new HomeController();
    }
    [TestCleanup]
    public void TestCleanup()
    {
        sut.Dispose();
        mockControllerContext = null;
    }
    [TestMethod]
    public void Index_Should_Return_Default_View()
    {

        // Expectations
        mockControllerContext.SetupGet(x => x.HttpContext.Request.ApplicationPath)
            .Returns("/foo.com");
        sut.ControllerContext = mockControllerContext.Object;

        // Act
        var failure = sut.Index();

        // Assert
        Assert.IsInstanceOfType(failure, typeof(ViewResult), "Index() did not return expected ViewResult.");
    }
}

Here's how I used the ControllerContext to pass a fake Application path:

[TestClass]
public class ClassTest
{
    private Mock<ControllerContext> mockControllerContext;
    private HomeController sut;

    [TestInitialize]
    public void TestInitialize()
    {
        mockControllerContext = new Mock<ControllerContext>();
        sut = new HomeController();
    }
    [TestCleanup]
    public void TestCleanup()
    {
        sut.Dispose();
        mockControllerContext = null;
    }
    [TestMethod]
    public void Index_Should_Return_Default_View()
    {

        // Expectations
        mockControllerContext.SetupGet(x => x.HttpContext.Request.ApplicationPath)
            .Returns("/foo.com");
        sut.ControllerContext = mockControllerContext.Object;

        // Act
        var failure = sut.Index();

        // Assert
        Assert.IsInstanceOfType(failure, typeof(ViewResult), "Index() did not return expected ViewResult.");
    }
}

以下是如何设置的示例：模拟 HttpContext HttpRequest 和 HttpResponse for UnitTests（使用 Moq）

请注意真正有助于简化此模拟类的使用的扩展方法：

var mockHttpContext = new API_Moq_HttpContext();

var httpContext = mockHttpContext.httpContext();

httpContext.request_Write("<html><body>".line()); 
httpContext.request_Write("   this is a web page".line());  
httpContext.request_Write("</body></html>"); 

return httpContext.request_Read();

以下是如何编写单元测试的示例使用起订量检查 HttpModule 是否按预期工作：使用 Moq 包装 HttpRequest 的 HttpModule 单元测试

更新：此 API 已重构为

HttpContextFactory.cs
这些多个 Http* 扩展方法文件

Here is an example of how you can set this up: Mocking HttpContext HttpRequest and HttpResponse for UnitTests (using Moq)

Note the extension methods which really help to simplify the usage of this mocking classes:

var mockHttpContext = new API_Moq_HttpContext();

var httpContext = mockHttpContext.httpContext();

httpContext.request_Write("<html><body>".line()); 
httpContext.request_Write("   this is a web page".line());  
httpContext.request_Write("</body></html>"); 

return httpContext.request_Read();

Here is an example of how to write a Unit Test using moq to check that an HttpModule is working as expected: Unit Test for HttpModule using Moq to wrap HttpRequest

Update: this API has been refactored to

HttpContextFactory.cs
these multiple Http* Extension Methods files

var httpResponse = new HttpResponseMessage(HttpStatusCode.OK);
httpResponse.Content = new StringContent("Your response text");

var httpResponse = new HttpResponseMessage(HttpStatusCode.OK);
httpResponse.Content = new StringContent("Your response text");
