How to write test class for Webservice Callout?

I have this main class which uses webservice callout that I am not familiar with and I need to write test class for that. Can someone please help me figure out this one? 
public BectranWebService.bectranServiceResult createCustomer(BectranWebService.bectranServiceRequest arg0) {
    BectranWebService.createCustomer request_x = new BectranWebService.createCustomer();
    request_x.arg0 = arg0;
    BectranWebService.createCustomerResponse response_x = new BectranWebService.createCustomerResponse();
    Map<String, BectranWebService.createCustomerResponse> response_map_x = new Map<String, BectranWebService.createCustomerResponse>();
    response_map_x.put('response_x', response_x);
    WebServiceCallout.invoke(
      this,
      request_x,
      response_map_x,
      new String[]{endpoint_x,
      '',
      'http://ws.services.bectran.com/',
      'createCustomer',
      'http://ws.services.bectran.com/',
      'createCustomerResponse',
      'BectranWebService.createCustomerResponse'}
    );
    response_x = response_map_x.get('response_x');
    return response_x.return_x;
}
public BectranWebService.additionalInfoBean getAdditionalAttributesForCreditApp(BectranWebService.loginInfoBean arg0,String arg1,String arg2) {
    BectranWebService.getAdditionalAttributesForCreditApp request_x = new BectranWebService.getAdditionalAttributesForCreditApp();
    request_x.arg0 = arg0;
    request_x.arg1 = arg1;
    request_x.arg2 = arg2;
    BectranWebService.getAdditionalAttributesForCreditAppResponse response_x = new BectranWebService.getAdditionalAttributesForCreditAppResponse();
    Map<String, BectranWebService.getAdditionalAttributesForCreditAppResponse> response_map_x = new Map<String, BectranWebService.getAdditionalAttributesForCreditAppResponse>();
    response_map_x.put('response_x', response_x);
    WebServiceCallout.invoke(this,
                             request_x,
                             response_map_x,
                             new String[]{endpoint_x,
                                          '',
                                          'http://ws.services.bectran.com/',
                                          'getAdditionalAttributesForCreditApp',
                                          'http://ws.services.bectran.com/',
                                          'getAdditionalAttributesForCreditAppResponse',
                                          'BectranWebService.getAdditionalAttributesForCreditAppResponse'
                                          });
    response_x = response_map_x.get('response_x');
    return response_x.return_x;
    }
