c# - routing and integration testing webapi via selfhosting -

i using code:

[fact] public void valuecontroller_withgetmethos_shouldreturnvaliddata_nobaseclass() {     var configuration = new httpselfhostconfiguration("http://localhost:64466");     configuration.includeerrordetailpolicy = includeerrordetailpolicy.always;     configuration.services.replace(typeof(iassembliesresolver), new webapiclassbase.testassemblyresolver(typeof(valuescontroller)));              configuration.routes.maphttproute(             name: "defaultapi",             routetemplate: "api/{controller}/{id}",             defaults: new { id = routeparameter.optional }         );      var server = new httpselfhostserver(configuration);     try     {     server.openasync().wait();      var request = new httprequestmessage     {         requesturi = new uri("http://localhost:64466/api/values"),         method = httpmethod.get     };      var client = new httpclient(server);     using (httpresponsemessage response = client.sendasync(request).result)     {         response.should().not.be.null();         response.issuccessstatuscode.should().be.true();          string[] result = response.content.readasasync<string[]>().result;          result.length.should().be.equalto(4);         result[0].should().be.equalto("http://tostring.it");         result[1].should().be.equalto("http://imperugo.tostring.it");         result[2].should().be.equalto("http://twitter.com/imperugo");         result[3].should().be.equalto("http://www.linkedin.com/in/imperugo");     }     }         {     configuration.dispose();     server.dispose();     } } 

inspired this, contains relevant valuescontroller. have noticed had adapt routing:

configuration.routes.maphttproute(     name: "defaultapi",     routetemplate: "api/{controller}/{id}",     defaults: new { id = routeparameter.optional } ); 

according 1 in webapiconfig. however, when try access action attribute routing this:

route("calculator/addtwonumbers/a/{a}/b/{a}")] public ihttpactionresult addtwonumbers(payload payload) 

i 404 - not found error. have define declarative routing? if so, integration testing seems quite tedious. feedback appreciated. thanks.

ps:

i tried:

configuration.maphttpattributeroutes(); 

which not seem help

you need setup attributerouting before default route configured.

configuration.maphttpattributeroutes(); configuration.routes.maphttproute(     name: "defaultapi",     routetemplate: "api/{controller}/{id}",     defaults: new { id = routeparameter.optional } ); 

routes evaluated in order added routecollection. if default route comes first, match incoming routes before attribute routes have chance matched.
