Question

I have this method in asp.net ajax enabled mvc service

[OperationContract]
public TestRun GetTestSuite(string testSuitName) {
   TestRun testRun = 
      AdapterFactory.CreateTestRunAdapter().GetByTestSuiteName("testSuit");
   return testRun;
} 

Where TestRun is Created using entities framework against TestRun table.

I am using following ajax method

function getTestSuite() {
            $.ajax({
                type: "POST",
                url: "Services/TestRunService.svc/GetTestSuite",
                data: '{"testSuitName" : "' + testSuiteName + '"}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (response) {
                },

                //If the call fails
                error: function (xhr, textStatus, errorThrown) {
                    alert(errorThrown);
                }
            })
        }

I get undefined error. If I return string from service it works. Do I need to change

dataType: “json” to something else ?

Answer 1

Is the TestRun class marked with the [DataContract] attribute?
