基于改进Markov模型软件测试策略

针对已有软件测试Markov模型与工程实践不符的情况，通过引入软件需求覆盖率改进Markov模型。在改进的Markov模型基础上，本文以软件测试过程中测试总代价最小为控制目标，采用交叉熵方法修正测试剖面，由优化测试剖面生成测试用例序列。仿真结果表明这种方法能够有效地降低软件测试总代价，是一种有效的软件测试方法。

Software Testing Strategy Based on Improved Markov Model

A software testing method of optimizing testing strategy based on improved Markov model is presented in this pa?per. This method uses a new stochastic optimization method called Cross Entropy method. By iterative correcting of the testing profile in Markov model, we consider the minimization of testing cost and try to generate testing data automatically. The ex?perimental results show that this optimization method is a promising option for tackling this problem. It can reduce the soft?ware testing cost effectively.
