How to instantiate a BSP controller manually

Question

I tried initially

DATA: cl_rest_bo_list TYPE REF TO zcl_rm_rest_bulk_orders.
CREATE OBJECT cl_rest_bo_list.
cl_rest_bo_list->request->if_http_request~set_method( 'GET' ).
cl_rest_bo_list->do_request( ).

This resulted into an abend, accessing request which was not initialized.

Then I tried to instantiate the request and the response

DATA: cl_rest_bo_list TYPE REF TO zcl_rm_rest_bulk_orders.
DATA: cl_request  TYPE REF TO cl_http_request.
DATA: cl_response TYPE REF TO cl_http_response.
CREATE OBJECT cl_rest_bo_list.
CREATE OBJECT cl_request.
CREATE OBJECT cl_response.
request->if_http_request~set_method( 'GET' ).
cl_rest_bo_list->request = cl_request.
cl_rest_bo_list->response = cl_response.    
cl_rest_bo_list->do_request( ).

This, at least, does not abend, but the set_method return error code here and does not actually set the method.

  system-call ict
    did
      ihttp_scid_set_request_method
    parameters
      m_c_msg                            " > c handle
      method                             " > method
      m_last_error.                      " < return code

Since Google does not know about ihttp_scid_set_request_method, I am pretty sure that I am doing this wrong. Maybe there is no provision to instantiate BSP controllers, though I am not sure what this means for ABAP Unit testing BSP controllers.

As a solution for now I have lifted all business logic into a separate method which gets called/tested without trouble. Still, if anybody knows how to instantiate CL_BSP_CONTROLLER2 classes, that would be great.

Answer 1

As far as I know, the BSP controller can only be instantiated from within the ICF processing because it retrieves information about the call from the kernel. I'm not sure why you would want to install unit tests for the UI in the first place, unless you didn't separate the UI and the business logic as your comment about "lifting" suggests....
