如何使用Moq模拟ASP.NET MVC中的HttpContext?

httpcontext moq mocking asp.net-mvc c#

Geo · 技术社区 · 17 年前

[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).
    ...
 }

我的基本控制器有一个过度的初始化,get就是这个请求上下文。我想把这件事传下去,但我做得不对。

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

在哪里可以获得更多关于使用Moq模拟RequestContext和HttpContext的信息?我试图模仿饼干和一般的上下文。

HttpContext是只读的,但它实际上是从ControllerContext派生的,您可以设置它。

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

创建请求、响应并将它们都放到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010011001001。

这对我很有用,在为下面的代码编写测试用例时,我遇到了一个问题:

 var currentUrl = Request.Url.AbsoluteUri;

这是解决问题的线

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。

下面是一个如何设置的示例: Mocking HttpContext HttpRequest and HttpResponse for UnitTests (using Moq)

注意那些真正有助于简化模拟类使用的扩展方法:

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();

Unit Test for HttpModule using Moq to wrap HttpRequest

更新:此API已重构为

HttpContextFactory.cs
这些倍数 Http* Extension Methods

下面是我如何使用ControllerContext传递一个假的应用程序路径:

[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.");
    }
}
