c# - 单元测试asp.net路由映射扩展方法

Question

我有一个路由扩展类。我想测试 routecollection 的更新列表。这是摘录:

public static void MapMyRoutes(this RouteCollection routes)
{
    //do some stuff
    routes.MapHttpRoute(null, controllerPath.Path, new { @namespace = controllerPath.Namespace, controller = controllerPath.ControllerName, id = UrlParameter.Optional });
}

我想对这个扩展进行单元测试，但不知道如何从路由集合中提取映射的 url:

这是一个测试:

[TestMethod]
public void TestMapMyRoutesMapsCorrectly()
{
    var routes = new RouteCollection();
    routes.MapMyRoutes();

    foreach (var route in routes)
    {
        Assert.AreEqual(route.??, "v1/api/myRoute");
    }
}

RoutesCollection被定义为 Collection<RouteBase>所以将每个项目作为路线转换，即:

foreach (var route in routes.Cast<Route>())
{
    // Url may not in fact be the correct property …
    Assert.AreEqual(route.Url, "v1/api/myRoute");
}
