            );
            response_x = response_map_x.get('response_x');
return response_x.result;
        }
    }
}

Create Service Mockup:
Sample Mockup class:
Create Mockupclass:
------------------------
global class YourWebServiceMockImpl implements WebServiceMock {
   global void doInvoke(
           Object stub,
           Object request,
           Map<String, Object> response,
           String endpoint,
           String soapAction,
           String requestName,
           String responseNS,
           String responseName,
           String responseType) {

        // Create response element from the autogenerated class.
        // Populate response element.
        // Add response element to the response parameter, as follows:
        response.put('response_x', responseElement);
   }
}

Original Mockup class:
globalclass GeneratedRecordCreationServiceMockupcls implements WebServiceMock {
       globalvoid doInvoke(
           Object stub,
           Object request,
           Map<String, Object> response,
           String endpoint,
           String soapAction,
           String requestName,
           String responseNS,
           String responseName,
           String responseType) {

// Create response element from the autogenerated class.
        GeneratedRecordCreationService.createRecordResponse_element responseElement = new GeneratedRecordCreationService.createRecordResponse_element();
//Here createRecordResponse_element is an inner class in generated service class for preparing response
// Populate response element.
        responseElement.result = 'Welcome to Salesfoce';//here we have to set the value for the property result
// Add response element to the response parameter, as follows:
        response.put('response_x', responseElement);
   }
      
}


Test class:
@isTest
privateclass TestGeneratedRecordCreationService {

statictestMethodvoid myUnitTest() {
// TO DO: implement unit test
 Test.setMock(WebServiceMock.class, new GeneratedRecordCreationServiceMockupcls());

        GeneratedRecordCreationService.RecordCreationservicecls recordCreationObj = new  GeneratedRecordCreationService.RecordCreationservicecls();
       recordCreationObj.createRecord('Give input');
      //This method “createRecord” contains the webservice callout.
    }
}

So by using mockup class we can do test code coverage for the method which includes web service callout .

    I am writing a test class and I am getting this error: System.TypeException: Methods defined as TestMethod do not support Web service callouts
    Here is my Test class
    @isTest
    public class Test_CSS_SOAPEDS {

    @isTest static void testEchoString() {
    // This causes a fake response to be generated

    String title = 'Customer Name:CSS EDS WS Test ';
    String workorder = 'workorder1';
    String model = 'null'; //"ISC CM2150"; //"ISB CM850";
    String serialNumber = '46826048';
    String locale = 'en';
    string userGroup=System.Label.UserGroup;
    string userName=System.Label.UserName;
    string encryptedKey = CSS_SOAPEDS.getgenerateToken(userName,userGroup);
    string systemDate;
    string token=userName+';'+userGroup+';datetime-'+systemDate;
    System.debug('The encryptedKey '+encryptedKey);
    System.debug('The title id '+title);
    string session = CSS_SOAPEDS.login(encryptedKey,locale);
    // Call the method that invokes a callout
    Test.setMock(WebServiceMock.class, new EDSwebcalloutMockImpl());
    String output = CSS_SOAPEDS.createDS(session,title,serialNumber,model,workorder);
    System.debug('The output '+output);
    // Verify that a fake result is returned
    System.assertEquals('DSBDT3829', output);
    }
    }

    Below is my web service mock class

    @isTest
    global class EDSwebcalloutMockImpl implements WebServiceMock{
    global void doInvoke(
    Object stub,
    Object request,
    Map response,
    String endpoint,
    String soapAction,
    String requestName,
    String responseNS,
    String responseName,
    String responseType) {
    wwwKaidaraCom.createDiagnosticSessionResponse response_elem = new wwwKaidaraCom.createDiagnosticSessionResponse();
    wwwKaidaraComKaidaraservice.resultDiagnosticSession dsID = new wwwKaidaraComKaidaraservice.resultDiagnosticSession();
    dsID.ID='DSBDT3829';
    system.debug('DSBDT3829<><>' + dsID.ID);
    response_elem.return_x = dsID;
    response.put('response_x', response_elem);

    }
    }

    Can YOU help me with this?
    Thank You
