Research on technology of ATS test program auto generating driven by test requirement

Abstract

To solve the transplantable problem of test program set (TPS) in the automatic test system (ATS), a new automatic generation technology based on demand-driven ATS program is put forward. Firstly, it utilizes the test requirement set to replace the test program set, and the work of generating test program from test requirements is completed by test environment. In addition, the test requirements will automatically generate executable test programs on different platforms so as to achieve the unambiguous transplantation of test requirements among different platforms. Then, mapping mechanisms between different models can be studied by establishing test requirement model as the platform independent model (PIM) and test program as the platform special model (PSM). Besides, the “template+compile” method is adopted to realize the automatic generation of test program. Specifically, the test requirements are translated into the different test flow description languages (TFDL) of different platforms through XSLT template, and then a compiler shall be developed to translate TFSL into the intermediate programs of C language. Finally, executable programs or dynamic link library (DLL) will be automatically generated by the means of commercial compilers.
