如何存根HttpControllerContext [英] how to stub HttpControllerContext

问题描述

我试图单元测试一块code那被从的WebAPI（的OData）控制器调用，并需要在HttpControllerContext：

I am trying to unit-test a piece of code that gets called from a WebAPI (OData) controller and takes in an HttpControllerContext:

public string MethodToTest(HttpControllerContext context)
{
    string pub = string.Empty;

    if (context != null)
    {
        pub = context.Request.RequestUri.Segments[2].TrimEnd('/');
    }

    return pub;
}

要进行单元测试这一点，我需要一个HttpControllerContext对象。我应该怎么做呢？我最初是想用微软正版正货存根，但HttpControllerContext不似乎有一个接口（为什么？），因此多数民众赞成似乎没有成为一种选择。如果我只是新的一个新的HttpControllerContext对象，也许存根其构造函数的参数？或使用该起订量架构（而不是！）

To Unit-test this i need an HttpControllerContext object. How should i go about it? I was initially trying to stub it with Microsoft Fakes, but HttpControllerContext doesnt seem to have an interface (why??), so thats doesnt seem to be an option. Should i just new up a new HttpControllerContext object and maybe stub its constructor parameters? Or use the Moq framework for this (rather not!)

推荐答案

您可以简单地实例化一个 HttpControllerContext 并指定上下文对象给它，除了路由信息（您可以模拟所有这些）：

You can simply instantiate an HttpControllerContext and assign context objects to it, in addition to route information (you could mock all of these):

var controller = new TestController();
var config = new HttpConfiguration();
var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost/api/test");
var route = config.Routes.MapHttpRoute(null, "api/{controller}/{id}");
var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "controller", "test" } });

controller.ControllerContext = new HttpControllerContext(config, routeData, request);
controller.Request = request;
controller.Request.Properties[HttpPropertyKeys.HttpConfigurationKey] = config;

// Call your method to test
MethodToTest(controller);

HttpControllerContext 只是一个容器，这样就不必被嘲笑自己。

HttpControllerContext is simply a container so it does not have to be mocked itself.
