Safety-Critical Software Automatic Testing System Based on Keyword Driven Script

An approach for designing a safety-critical software automatic testing system based on keyword driven script is presented and discussed. A lot of efficient test cases will be made formally with keyword driven script in order to establish the expert knowledge base of test cases. And the new-style software automatic testing system will be developed to implement automatic generation, automatic testing of test cases and automatic result comparison. This system can improve the level of test automation and test efficiency of the Railway Station Computer Interlocking Software more.
