本文介绍如何在ABAP单元测试中利用OSQL工具类CL_OSQL_TEST_ENVIRONMENT来模拟特定数据库表，如BKPF，确保测试的独立性和可控性。通过示例代码展示了如何创建、插入测试数据以及清理过程。

OSQL可以在ABAP单元测试运行时mock up特定的数据库表，使得单元测试独立于特定的运行系统。

其使用的工具类为：

CL_OSQL_TEST_ENVIRONMENT

示例代码 (在UT运行时，mock up数据库表BKPF) ：

CLASS ltc_abc_fun02 DEFINITION FOR TESTING FINAL
                                   DURATION SHORT
                                   RISK LEVEL HARMLESS.

    " Mock up: BKPF
    lt_bkpf = VALUE #( ( bukrs = 'CFP1' belnr = '0100000118' gjahr = '2018' ) ).
    mo_osql_obj->insert_test_data( i_data = lt_bkpf ).
