组合的测试用例设计与评价方法

在软件开发过程中，软件测试成为唯一的选择，在保证软件质量前提下，设计与工程人员的首要工作就是降低测试用例数量，优化测试用例设计，减轻测试工作量。提出组合测试技术和正交实验方法在软件测试中的应用方法，分析了成对组合的测试用例方法，设计了测试用例的生成方法，设计测试评价方法。在一应用系统的负载测试实验中，使用R法和方差分析方法，分析了网络带宽、处理器速度、并发用户等负载因素对系统响应时间的影响，确定最优的性能指标和测试组合。

Method of Combinatorial Test Case Design and Assessment

The software testing becomes the necessary choice in software development. For the assurance of software quality,the mainly work for the software designer and engineer is to decrease the quantity of test case,optimize the design of test case,and low the testing work load. The combinatorial testing technology and the orthogonal experiment method were provided. The pair-wise of test case design method was analyzed,designing the method for the test case and the assessment criteria of test case. In a load testing solution for one ap-plication system,using R and variance analysis method,the load testing factor to one system response time was analyzed,including net-work bandwidth,processor speed and concurrency users etc. ,the optimization performance criteria to the system was determined,and the combinatorial testing factors were selected.
