为了提高迭代式增量软件开发中的回归测试效率、改善测试脚本和用例的维护性和复用性,基于关键字驱动的思想设计了层次化的测试自动化框架模型,提出了对应的三层关键字设计方法.通过C++项目-机械系统动力学CAE平台MWorks回归自动化测试框架详细的系统实现证明了模型的可行性,合理的关键字划分隔离了测试脚本开发人员、测试用例开发人员和测试执行人员关注的问题,有助于组织和管理测试和测试用例,使得框架便于使用、维护和扩展.测试工具的多进程并行和异常处理进一步提高了测试效率.%Aiming at the improvement of the efficiency of regression testing and the maintainability and reusability of automated test scripts and cases in the iterative and incremental software development, a model of test automation framework based on keyword-driven as well as the approach for designing the keywords is brought up, and then the system implementation of an CAE platform-Mworks is presented to demonstrate the feasibility. The isolation of problems which the test script developers, the test case developers and the test executors care about by the suitable keyword classification make the framework easy to use,maintain and expand. The efficiency is further improved by multi-process parallel execution and exception handling of the test tool.
