Abap Unit - Test double result is differnt if full test or single test

[FredericGirod]

Hi Team,

I start using Test double with Abap Unit ( I am used to use Mock ).

The issue is really simple, I have two test methods.

When I run both methods, the first one failed.

When I run just the first one, it success.

  METHOD new_batch_id_is_ok_01.
    cl_abap_testdouble=>configure_call( o_data )->returning( '209912345' ).
    o_data->get_new_batch_id( '99' ).
    cl_abap_unit_assert=>assert_equals(
      act = o_cut->get_new_batch_id( '2099' )
      exp = '2099-12345' ).
  ENDMETHOD.

  METHOD new_batch_id_is_ko_01.
    cl_abap_testdouble=>configure_call( o_data )->raise_exception( o_exception ).
    o_data->get_new_batch_id( '98' ).
    cl_abap_unit_assert=>assert_equals(
      act = o_cut->get_new_batch_id( '98' )
      exp = '' ).
  ENDMETHOD.

the testdouble creation is in the SETUP method :

  METHOD setup.
    o_data  ?= cl_abap_testdouble=>create( 'ZIF_ISU_DEPLOY_BATCH_DATA' ).
    o_rules ?= cl_abap_testdouble=>create( 'ZIF_ISU_DEPLOY_BATCH_RULES' ).
    o_cut   = zcl_isu_deploy_factory=>get_instance( )->get_batch_instance(
                    io_data_instance  = o_data
                    io_rules_instance = o_rules ).
    o_exception = NEW #( ).
  ENDMETHOD.

Is there a clean action to be done between test double ?

Hi, could you share (or review) get_batch_instance code?

Ok,

so the issue is not related to doubleframework. It is because I use Design Pattern SingleTon to create my O_CUT.

So when I called the second time the Get_Instance( ) from the Factory, it replies directly the first Instance created, with the O_data and O_Rules of the first Instance.

Solution replace :

    o_cut   = zcl_isu_deploy_factory=>get_instance( )->get_batch_instance(
                    io_data_instance  = o_data
                    io_rules_instance = o_rules ).

    o_cut   = new zcl_isu_deploy_batch( io_data_instance  = o_data                                                             
                                        io_rules_instance = o_rules ).
