测试类的结构

测试类在特殊单元测试包中创建为本地类。

这是测试类的基本结构：

CLASS lcl_test DEFINITION
               FOR TESTING
               DURATION SHORT
               RISK LEVEL HARMLESS.

PRIVATE SECTION.
  DATA:
    mo_cut TYPE REF TO zcl_dummy.

  METHODS:
    setup,

  "********* 30 chars *********|
  dummy_test                     for testing.
ENDCLASS.

CLASS lcl_test IMPLEMENTATION.
  METHOD setup.
    CREATE OBJECT mo_cut.
  ENDMETHOD.

  METHOD dummy_test.
    cl_aunit_assert=>fail( ).
  ENDMETHOD.
ENDCLASS.

用 FOR TESTING 声明的任何方法都是单元测试。setup 是在每次测试之前执行的特殊方法。
