C＃PACT - 消費者驅動的聯繫測試 - 爲提供者編寫單元測試

Question

我試圖讓我的腦袋約PACT，我正在使用PACT-Net庫來實現此目的。

我對消費者的單元測試工作正常，但我試圖在提供程序上設置單元測試。我使用的是在Visual Studio中使用Web API模板時加載的基本Web API項目 - 它創建了Values API控制器。我只是測試Get IEumerable<string>方法，以此作爲流程的端到端測試。我也是在PACT-Net github網站上的例子。下面是單元測試我到目前爲止：

[Fact] 
    public void EnsureValuesReturnedFromApi() 
    { 
     var config = new PactVerifierConfig 
     { 
      Outputters = new List<IOutput> 
      { 
       new XUnitOutput(_output) 
      } 
     }; 

    using (WebApp.Start<TestStartup>(serviceUri)) 
    { 
     var pactVerifier = new PactVerifier(config); 
     pactVerifier.ProviderState($"{serviceUri}/provider-states") 
      .ServiceProvider("Values API", serviceUri) 
      .HonoursPactWith("Consumer") 
      .PactUri("http://localhost:8080/pacts/provider/Values%20API/consumer/Consumer/latest") 
      .Verify(); 
    } 
} 

當過我運行單元測試，我得到以下錯誤：

1 interaction, 1 failure 

Failed interactions: 

* Getting a list given When I want the values 

我想我的問題是，我需要實際測試對/ api/values的HTTP調用還是缺少其他東西？

感謝

所以說話的同事，得到一個提示後，則下跌到啓動類。我沒有意識到它有效地啓動Web應用程序，以便

public class TestStartup 
{ 
    public void Configuration(IAppBuilder app) 
    { 
     var startup = new Startup(); 
     app.Use<ProviderStateMiddleware>(); 
     startup.Configuration(app); 
    } 
} 

調用應用程序中的啓動類：

public class Startup 
{ 
    public void Configuration(IAppBuilder app) 
    { 
     var httpConfig = new HttpConfiguration(); 
     httpConfig.MapHttpAttributeRoutes(); 

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

     var appXmlType = httpConfig.Formatters.XmlFormatter.SupportedMediaTypes 
            .FirstOrDefault(t => t.MediaType == "application/xml"); 
     httpConfig.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType); 

     app.UseWebApi(httpConfig); 
    } 
} 

和我的單元測試通過。希望這可以幫助某人。
