Module Objectives Purpose of ABAP Unit Creating Unit Tests Fixture Methods ABAP Unit Test Class Wizard ABAP Unit Test Classes in ADT Purpose of ABAP Unit ABAP Unit is part of the test landscape for ABAP programs. ABAP Unit lets you implement unit tests. ABAP unit tests are methods of specially designated ABAP classes. Test methods work as scripts, with which code under test can be run, and with which the results of a test can be evaluated. ABAP unit lets you test the code at unit level, independent of the entire solution. Creating Unit Tests ABAP unit tests are implemented in the form of test methods in local test classes in any ABAP programs. The expected results are checked with static methods of help class CL_ABAP_UNIT_ASSERT or CL_AUNIT_ASSERT . Unit test Test Properties Risk Level Harmless – the test does not affect any existing processes and/or Database data. Dangerous– the test will change Database or Persistent Data Critical – the test will affect customizing data Duration Sh
