ABAPu3000Unit'su3000coverage

Question

Hi all
I had written a test code of abap, it is for test a form of abap pgm.
Now , I want to know the percent of coverage about this test code. How should I do.
For example:
This is my abap pgm.
FORM GET_LFG USING    VALUE(L_AGE) TYPE N
             CHANGING L_FLG        TYPE N
  IF L_AGE > 60.
    L_FLG = 1.
  ELSEIF L_AGE >= 40 AND L_AGE <= 60.
    L_FLG = 2.   
  ELSE.
    L_FLG = 3.  
  ENDIF.
ENDFORM.
This is my test code.
      CLASS lcl_test DEFINITION
CLASS LCL_TEST DEFINITION FOR TESTING  "#AU Duration Short
  INHERITING FROM CL_AUNIT_ASSERT.     "#AU Risk_Level Harmless
  PRIVATE SECTION.
    METHODS TEST_GET_LFG_SIMPLE_CALL FOR TESTING.
ENDCLASS.                    "lcl_test DEFINITION
      CLASS lcl_test IMPLEMENTATION
CLASS LCL_TEST IMPLEMENTATION.
  METHOD TEST_GET_LFG_SIMPLE_CALL.
  Setup parameters for the call...
    DATA :
      L_AGE(2)      TYPE N,
      L_FLG         TYPE N.
  Perform the call
    L_AGE = 61.
    PERFORM GET_AGE USING    L_AGE
                    CHANGING L_FLG.
  Check returned values
    ASSERT_EQUALS( ACT = L_FLG EXP = 1 MSG = 'ERROR FOR OVER 60 YEARS' ).
  Perform the call
    L_AGE = 55.
    PERFORM GET_AGE USING    L_AGE
                    CHANGING L_FLG.
  Check returned values
    ASSERT_EQUALS( ACT = L_FLG EXP = 2 MSG = 'ERROR FOR FORM 40 TO 60 YEARS' ).
  ENDMETHOD.                    "TEST_GET_GLE_SIMPLE_CALL
ENDCLASS.                    "lcl_test IMPLEMENTATION
The test code just check two cases. the other case(<40) is not be tested.
thanks

Hello Lhz,
from netweaver release 7.02 onwards unit test execution with combined coverage measurement is integrated into the IDE (transaction SE80). For the older releases these are seperate tools. In case you are in your development system the follwoing approach may help.
Any code change to your report will also reset any coverage measurement (TA SCOV).
After a change execute your unit tests and review the effects in transaction SCOV. Please note that SCOV needs to be switch on explictely and that the so called data collection of SCOV happens not event based but on regular schedule. This can delay the arrival of your actions in the coverage results.
Kind Regards
