Process optimization for testing of domain specific languages in industrial automation

Software testing is essential part of software development. The goal of the testing process is not only to enhance the quality and robustness of the software but also verify the correctness and non functional requirements of the software under all working conditions. Large software has their large testing suites to verify the stability of legacy features. Testing processes have huge challenges to maintain effectiveness and efficiency of the legacy test cases. There are many different processes and techniques available all technique or processes have their advantages and limitations. A tailored testing process has been tried to utilize all technique together to improvise the benefits and efficiency of testing in the industrial automation domain. This paper tries to explain a customized approach of utilizing the available testing techniques in such a way that it enhances the effectiveness and efficiency of regression testing, thus improving the time to market of large product-line Industrial automation software.
