如何正确单元测试OData v6.0控制器？

Question

我正在尝试对OData控制器进行单元测试,但API已更改,之前推荐的方法我尝试不起作用 - 目前我正在使用

没有注册非OData HTTP路由.

当试图将ODataQueryOptions实例化为传递给控制器​​的Get方法时

我当前的代码(基于像回答这一个):

       [TestMethod()]
    public void RankingTest()
    {
        var serviceMock = new Mock<IVendorService>();
        serviceMock.SetReturnsDefault<IEnumerable<Vendor>>(new List<Vendor>()
        {
           new Vendor() { id = "1" }
        });

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://localhost/odata/Vendor");

        ODataModelBuilder builder = new ODataConventionModelBuilder();
        builder.EntitySet<Vendor>("Vendor");
        var model = builder.GetEdmModel();

        HttpRouteCollection routes = new HttpRouteCollection();
        HttpConfiguration config = new HttpConfiguration(routes) { IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always };

        // attempting to register at least some non-OData HTTP route doesn't seem to help
        routes.MapHttpRoute("Default", "{controller}/{action}/{id}",
            new
            {
                controller = "Home",
                action = "Index",
                id = UrlParameter.Optional
            }
            );
        config.MapODataServiceRoute("odata", "odata", model);
        config.Count().Filter().OrderBy().Expand().Select().MaxTop(null);
        config.EnsureInitialized();

        request.SetConfiguration(config);
        ODataQueryContext context = new ODataQueryContext(
            model,
            typeof(Vendor),
            new ODataPath(
                new Microsoft.OData.UriParser.EntitySetSegment(
                    model.EntityContainer.FindEntitySet("Vendor"))
            )
        );


        var controller = new VendorController(serviceMock.Object);
        controller.Request = request;

        // InvalidOperationException in System.Web.OData on next line:
        // No non-OData HTTP route registered
        var options = new ODataQueryOptions<Vendor>(context, request);

        var response = controller.Get(options) as ViewResult;

    }

感谢您的任何想法或指示!

EnableDependencyInjection从System.Web.OData.Extensions.HttpConfigurationExtensions类中添加对方法的调用:

HttpConfiguration config = new HttpConfiguration();

//1        
config.EnableDependencyInjection();

//2 
config.EnsureInitialized();
