使用Rhinomock的C#Mock Request.Browser.MajorVersion

我在MVC控制器中有以下代码：

        var isIe6 = Request.Browser.Type.ToUpper().Contains("IE") && Request.Browser.MajorVersion < 7;

    public string Method()
    {
        return Request.Browser.MajorVersion.ToString();
    }

这只会在安装程序中引发一个异常，表示需要设置浏览器。我也尝试过将它与上面的

HttpBrowserCapabilitiesWrapper

结合使用，但它仍然表示需要设置浏览器

如何在MVC中创建stub/mock out Request.Browser.MajorVersion

一些测试代码（如果有人需要）：

    private BasketController sut;
    protected HttpRequestBase HttpRequest;

    [Test]
    public void ShowsMajorVersionDoesNotWork()
    {
        // Arrange
        HttpRequest.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(new HttpBrowserCapabilities
        {
            Capabilities = new Dictionary<string, string>
            {
                {"majorversion", "11"},
                {"MajorVersion", "11"},
                {"browser", "IE"},
                {"isMobileDevice","false"}
            }
        }));
        //HttpRequest.Stub(a => a.Browser.MajorVersion).Return(11); // Throws Exception
        sut = new BasketController()
        {
            Url = new UrlHelper(new RequestContext(HttpContext, new RouteData()), new RouteCollection())
        };
        sut.ControllerContext = new ControllerContext(HttpContext, new RouteData(), sut);


        // Act
        var result = sut.Method();

        // Assert
        Assert.That(result, Is.EqualTo("11")); // Fails, always returns 0
    }

您可以使用

BrowserCapabilitiesFactory

（如上所述）创建

HttpBrowserCapabilities

，使用，并且类似地，您可以使用正确的字符串模拟任何其他浏览器

MajorVersion

：

public HttpRequestBase GetInterenetExplorer11StubRequest()
{
    return GetBrowserCapabilitiesStub("Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko");
}

public HttpRequestBase GetBrowserCapabilitiesStub(string userAgentString)
{
    var browser = new HttpBrowserCapabilities
    {
        Capabilities = new Hashtable { { string.Empty, userAgentString } }
    };
    var factory = new BrowserCapabilitiesFactory();
    factory.ConfigureBrowserCapabilities(new NameValueCollection(), browser);
    var request = MockRepository.GenerateStub<HttpRequestBase>();
    request.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(browser));
    return request;
}

公共HttpRequestBase GetInterenetExplorer11StubRequest（） { 返回GetBrowserCapabilitiesStub（“Mozilla/5.0（WindowsNT6.3；Trident/7.0；rv:11.0）像Gecko”）； } 公共HttpRequestBase GetBrowserCapabilitiesStub（字符串userAgentString） { var browser=新的HttpBrowser功能 { 能力=新哈希表{{string.Empty，userAgentString} }; var factory=新的BrowserCapabilitiesFactory（）； ConfigureBrowserCapabilities（新的NameValueCollection（），浏览器）； var request=MockRepository.GenerateStub（）； request.Stub（a=>a.Browser）.Return（新的HttpBrowserCapabilitiesWrapper（浏览器））； 返回请求； }

请给我们看一个（即显示问题的最简单的单元测试）。我会在编译时将其标记为答案，最后一行是错误点！我已经更新了代码，用stubbed Browser属性创建了HttpRequest存根

    public string Method()
    {
        return Request.Browser.MajorVersion.ToString();
    }

public HttpRequestBase GetInterenetExplorer11StubRequest()
{
    return GetBrowserCapabilitiesStub("Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko");
}

public HttpRequestBase GetBrowserCapabilitiesStub(string userAgentString)
{
    var browser = new HttpBrowserCapabilities
    {
        Capabilities = new Hashtable { { string.Empty, userAgentString } }
    };
    var factory = new BrowserCapabilitiesFactory();
    factory.ConfigureBrowserCapabilities(new NameValueCollection(), browser);
    var request = MockRepository.GenerateStub<HttpRequestBase>();
    request.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(browser));
    return request;
}
