Owin 测试（自托管）在使用 DI 时未注册网络 api 路由

Question

我正在尝试实施 Microsoft.Owin.Testing/3.0.1 for WebApi 2 integration tests. Everything works fine except when I add attribute routing。路线无法识别或我无法正确注册。我很确定它与测试时未使用的 api 控制器依赖注入有关。

我的价值观api控制器

 [RoutePrefix("api")]
        public class ValuesApiController : ApiController
        {
            private readonly ValuesControllerService _valuesControllerService;

            public ValuesApiController(ValuesControllerService valuesControllerService)
            {
                _valuesControllerService = valuesControllerService;
            }

            // GET api/values
            [HttpGet]
            [Route("values")]
            public async Task<IHttpActionResult> Get()
            {
                if (_valuesControllerService == null)
                    throw new ArgumentException("valuesControllerService");

                return Ok(new[] { "value1", "value2" });
            }
        }

我正在使用 Castle Windsor 解决 API 控制器使用 (source):

GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerActivator), new WindsorCompositionRoot(_container));
ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(_container));

我正在 Global.asax 中注册我的 WebApi 路由，因此当 运行 应用程序（而不是测试）时它被正确注册。

public class WebApiApplication : HttpApplication
    {
        protected void Application_Start()
        {
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }

测试的时候，我在Startup之后调用注册。这是我使用的示例测试 (test source):

[Test]
        public async void GetValueTestForStartup1()
        {
            using (var server = TestServer.Create<Startup1>())
            {
                using (var client = new HttpClient(server.Handler))
                {
                    var request = await client.GetAsync(_url);

                    Assert.IsTrue(request.IsSuccessStatusCode);
                }
            }
        }

下面是我尝试过的一些 Startup 实现：

internal class Startup1
        {
            public void Configuration(IAppBuilder app)
            {
                new Startup().ConfigureForIntegrationTests(app, x => x.Kernel.ComponentModelBuilder.AddContributor(new SingletonEqualizer()));
                GlobalConfiguration.Configuration.Services.Replace(typeof(IAssembliesResolver), new TestWebApiResolver());
                GlobalConfiguration.Configure(WebApiConfig.Register);
            }
        }

404 when executing a request

internal class Startup2
{
    public void Configuration(IAppBuilder app)
    {
        new Startup().ConfigureForIntegrationTests(app, x => x.Kernel.ComponentModelBuilder.AddContributor(new SingletonEqualizer()));
        GlobalConfiguration.Configure(WebApiConfig.Register);
        GlobalConfiguration.Configuration.EnsureInitialized();
    }
}

System.InvalidOperationException : This method cannot be called during the application's pre-start initialization phase.

internal class Startup3
    {
        public void Configuration(IAppBuilder app)
        {
            new Startup().ConfigureForIntegrationTests(app, y => y.Kernel.ComponentModelBuilder.AddContributor(new SingletonEqualizer()));
            // Web API routes

            GlobalConfiguration.Configuration.MapHttpAttributeRoutes();

            GlobalConfiguration.Configuration.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            app.UseWebApi(GlobalConfiguration.Configuration);
            GlobalConfiguration.Configuration.Services.Replace(typeof(IAssembliesResolver), new TestWebApiResolver());
        }
    }

500 Internal Server error (probably because there is no parameterless constructor found).

有一个类似的 SO 问题 here about AutoFac. I must have looked over that response 但所有这一切的关键是用您自己的 HttpConfiguration 注册所有内容，而不是使用 GlobalConfiguration 对象。

我已经更新了 github code 所以测试现在工作正常！
