22、roduction A.1.1 Test Purposes (TP) For each test requirement a Test Purpose (TP) is defined. Test purposes shall be defined in a dedicated test purpose document as well as with TTCN-3 documentation tags in each test case of the ATS. Both documentations shall convey the same information for each test

23、 purpose. A.1.2 Test purpose naming convention The test purpose naming scheme corresponds to the test case identifier naming scheme and vice-versa. A.1.3 Test purpose structure The test purpose structure is according to the test suite structure (TSS). A.1.4 Test purpose format In the following, exam

24、ples for tabular test purpose descriptions are shown that shall be defined in the test purpose document. This representation is a direct mapping of the contents of the document tags in the ATS (such as purpose, remark, or verdict). The tabular descriptions are presented along with their correspondin

25、g TTCN-3 documentation tag equivalent. The test purpose reference shall be provided in a machine-readable format.
