Research And Application Of Optimization Method Of Scene Switching Path In Software Scene Test

With the development of software engineering technology, increasing software size and complexity, the cost of software testing is also growing. How to optimize the testing process, improve test efficiency has become a hot topic in today’s software industry.Scenario test, also known as use case test, is the software black box method based on use case driven approach. The disorder between scenarios causes the repeat of construction and withdrawn in scenario testing, which results in a high test cost.This paper analysis constitutes of scenario and scenario switching based on the research on scenario test. This paper gives the definition of the state implication and scenario implication relations and inference from the view of the structural decomposition of test scenario based on the composite state analysis, logical implication concept. The SIG(Scenario Implication Graph) is proposed from the scenario implication relationship, and then uses the graph theory method to solve the optimal path. Then given the system processing method of the graph, and compared with other methods. Finally applied this method to actual software project testing. First we analysis the project requirements and the core business processes and apply the method in the project on the basis of the analysis.The analysis shows that the optimization methods proposed in this paper has a certain cost optimization results. The optimization method is not reducing scenario collection or optimizing the single scenario test cost, but analysis the cost of switching between scenarios and the relationship between scenarios to determine the execution order.
