Trigger ALV handle_data_change event for unit test

Hi experts,

i try to test my ALV OO with a unit test.
So basiclly i try following:

Setup ALV
Load Data in ALV
Change Data (eg. just one cell) in ALV
Trigger handle_data_changed
Check if everything worked fine

So far i´ve tried with something like that:

I know is supposed to be changed in the Frontend, but i guess is somehow possible just by code.

My code for the unit test method is:

    f_cut->setup_alv( ).
    f_cut->tickets->lt_ticketlist = me->create_ticketlist( ).
    f_cut->tickets->go_alv_grid->refresh_table_display( ).
    READ TABLE f_cut->tickets->lt_ticketlist ASSIGNING <ls_ticketlist> WITH KEY object_id = '4000010502'.
    <ls_ticketlist>-pos = 2.
    DATA: it_pos TYPE lvc_t_pos.
    DATA: is_pos TYPE LVC_S_POS.
    is_pos-fieldname = 'POS'.is_pos-row_id = 6.
    APPEND is_pos to it_pos.
    f_cut->tickets->go_alv_grid->change_data_from_inside( it_cells = it_pos ).
    f_cut->tickets->go_alv_grid->if_cached_prop~set_prop(
    EXPORTING
      PROPNAME = 'GridModified'
      PROPVALUE = '1').
    f_cut->tickets->go_alv_grid->check_changed_data( ).

Got it on my own.
It was quiet simple

    ls_delta_cells-row_id    = sy-tabix.
    ls_delta_cells-fieldname = lv_fieldname.
    ls_delta_cells-value     = lv_value.
    APPEND ls_delta_cells TO lt_delta_cells.


    go_alv_grid->set_delta_cells(
      EXPORTING
   it_delta_cells = lt_delta_cells
    i_modified     = abap_true
    ).
    go_alv_grid->check_changed_data(  IMPORTING e_valid = lv_valid ).

That triggers data_changed
