ABAP Unit question

[Former Member]

Hello,

I am new to ABAP unit, and not really sure on how I can execute one ABAP unit test script.

Let's say I have the below code (extracted from SAPBC401_PRJD_ABAP_UNIT program in SAP ECC 6.0 system (SP9).

**&---------------------------------------------------------------------
**
**& Report  SAPBC401_PRJD_ABAP_UNIT
**&
**&---------------------------------------------------------------------
REPORT  sapbc401_prjd_abap_unit.

CLASS myclass DEFINITION.
  PUBLIC SECTION.
    CLASS-DATA text TYPE string.
    CLASS-METHODS set_text_to_x.
ENDCLASS.

CLASS myclass IMPLEMENTATION.
  METHOD set_text_to_x.
    text = 'U'.
  ENDMETHOD.
ENDCLASS.

* Test classes
CLASS mytest DEFINITION FOR TESTING.
  PRIVATE SECTION.
    METHODS mytestmethod FOR TESTING.
ENDCLASS.

CLASS mytest IMPLEMENTATION.
  METHOD mytestmethod.
    myclass=>set_text_to_x( ).
    cl_aunit_assert=>assert_equals( act = myclass=>text
                                    exp = 'X' ).
  ENDMETHOD.
ENDCLASS.

The simple question is, how I can execute the

mytestmethod

from

mytest

class?

If I just execute the above code using F8, I believe nothing is executed right?

I tried to append the below code, but it is also only executing the method in that particular class (not in the test case class).

start-of-selection.
myclass=>set_text_to_x( ).

Please help me to start...

Thanks in advanced.

PS: I have searched the below link, but still not understand how to execute a simple AUnit script.

Hello Hiroshi,

in general ABAP Unit tests are executed via a test driver. The class cl_aunit_task is however not released for public use. It is integrated in some SAP services and tools. E.g. in transaction SE38 you may invoke tests via menu execute/unit Tests.

ABAP Unit tests of SAP programs in customer environments are a special case however, they are disabled. The tests in package SABP_UNIT_SAMPLE are the only exception.

You may write and use our own tests of course.

Regards

Klaus

Dear Klaus,

Thanks very much! The link is very useful.

I implemented the below class for test, and now I got the idea how to continue!

 
class ZCL_WALLET definition
  public
  final
  create public .

*"* public components of class ZCL_WALLET
*"* do not include other source files here!!!
public section.

  data LIQUIDITY type I .

  methods CHECK_LIQUIDITY .
  methods GET_LIQUIDITY
    returning
      value(RE_LIQUIDITY) type STRING .
  methods PUT_IN
    importing
      !EUROS type I .

REPORT  Z_MAIN_ABAPUNIT.
class lcl_Wallet_Test definition for testing. "#AU Risk_Level Harmless

  private section.

    methods check_Liquidity for testing.

endclass.

class lcl_Wallet_Test implementation.

method check_Liquidity.
  data:
    my_Wallet type ref to zcl_Wallet,
    liquidity type i.

  create object my_Wallet.
  liquidity = my_Wallet->get_Liquidity( ).

  cl_Aunit_Assert=>assert_Equals(
    act = liquidity
    exp = 1 "purposely put 1 to show error
    msg = 'New wallet assumed empty' ).

  my_Wallet->put_In( euros = 12 ).
  cl_Aunit_Assert=>assert_Equals(
    act = my_Wallet->liquidity
    exp = 12
    msg = 'As many euros as put in before' ).
endmethod.

endclass.
