Abstract

Automatic generation of random self-checking CICS testcases D.L. Bird FF 7W, IBM Background of testcase generation The functional testing of large pieces of software requires a considerable quantity of test material, usually in the form of executable 'testcases'. It is desirable for these testcases to be created automatically. That is the purpose of a 'Testcase Generator', a program that creates random testcases for a specific piece of software. Testcase generation for PL/I compilers My first involvement in writing testcase generators was during the development of the PL/I Check-Out and Optimising Compilers. The method was ideal for testing compilers because the testcases could be made completely self-checking. As each random PL/I statement was added to the testcase under construction, the execution of that statement was predicted by the Generator. A self-checking statement could then be added to the testcase, to ensure that the random statement was correctly processed at
