Abstract
In today's software systems become increasingly complex studies. The majority of enterprises are no test designers. Therefore, the planning and design of test cases often the lack of modular design and institutionalized practices. Let testing members make it difficult to cooperate. The output of test case’s documentation are irregular and incomplete. Only it can do manual testing. It causes to waste time of manpower and cost. It can not achieve the automation of test cases and tools integration. In this paper, in order to resolve the current testers test case planning and design issues. Therefore reference Rational Unified Process, Unified Modeling Language, IEEE / EIA 12207 international standard, CMMI process improvement methodology, EIA / IEEE J-STD-016, test Maturity model Analysis methodology and experience. To define detailed definition of the testing process and the four steps of institutionalization. 1. To create a total vocabulary form. 2. To define the purpose and use case scenario description 3. To define test data 4. Depending on use case scenario description corresponds to the test case. Implemented through the order product case again, successfully identify a set of workable test cases solutions to the functional test, and effectively reduce test time and cost.
