单元测试Web服务 - 的HttpContext [英] Unit Testing Web Services - HttpContext

问题描述

我想写一个Web服务单元测试。我创建我的测试项目，参考我的Web项目（非服务引用，装配参考），然后写一些code测试Web服务 - 他们工作的罚款。不过，也有一些服务，确保通过使用到Web应用程序的用户登录 HttpContext.Current.User.Identity.IsAuthenticated 。

I want to write unit tests for a web service. I create my test project, reference my web project (not service reference, assembly reference), then write some code to test the web services - they work fine. However, there are some services which make sure the user is logged in to the web application by using HttpContext.Current.User.Identity.IsAuthenticated.

在测试的背景下，有没有这样的东西的HttpContext，因此测试总是失败。这些类型的Web服务应该怎样进行单元测试？

In the context of the tests, there is no such thing as HttpContext, so the tests always fail. How should these kinds of web services be unit tested?

推荐答案

<一个href=\"http://stackoverflow.com/questions/524457/how-do-you-mock-the-session-object-collection-using-moq\">Here是一个相关的讨论。

我停下来引用 HttpContext.Current 直接。并使用这个类来代替：

I stopped referencing HttpContext.Current directly. and use this class instead:

public class HttpContextFactory
{
    private static HttpContextBase m_context;
    public static HttpContextBase Current
    {
        get
        {
            if (m_context != null)
                return m_context;

            if (HttpContext.Current == null)
                throw new InvalidOperationException("HttpContext not available");

            return new HttpContextWrapper(HttpContext.Current);
        }
    }

    public static void SetCurrentContext(HttpContextBase context)
    {
        m_context = context;
    }
}

和使用 HttpContextFactory.Current 而不是 HttpContext.Current 在我们的code。

and use HttpContextFactory.Current instead of HttpContext.Current in our code.

然后你写这在您的测试：

Then you write this in your test:

        HttpContextFactory.SetCurrentContext(GetMockedHttpContext());

在这里GetMockedHttpContext（）是的此处，看起来像这样：

    private System.Web.HttpContextBase GetMockedHttpContext()
    {
        var context = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();
        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        var user = new Mock<IPrincipal>();     
        var identity = new Mock<IIdentity>();

        context.Setup(ctx => ctx.Request).Returns(request.Object);
        context.Setup(ctx => ctx.Response).Returns(response.Object);
        context.Setup(ctx => ctx.Session).Returns(session.Object);
        context.Setup(ctx => ctx.Server).Returns(server.Object);
        context.Setup(ctx => ctx.User).Returns(user.Object);
        user.Setup(x => x.Identity).Returns(identity.Object);
        identity.Setup(id => id.IsAuthenticated).Returns(true);
        identity.Setup(id => id.Name).Returns("test");

        return context.Object;
    }

它采用了<一个href=\"http://stackoverflow.com/questions/64242/rhino-mocks-typemock-moq-or-nmock-which-one-do-you-use-and-why\">mocking框架的所谓起订量

在您的测试项目，你必须添加一个引用的System.Web 和 System.Web.Abstractions ，其中， HttpContextBase 定义。

In your test project you have to add a reference to System.Web and System.Web.Abstractions, where HttpContextBase is defined.
