面向对象软件回归测试选择策略

回归测试在软件维护阶段是一个重要且必须的一个工作,它为修改后的软件的正确性提供保证,回归测试选择技术是选择已存在的原有程序的测试用例集构成新的测试用例来测试修改后软件,通过对已存在测试用例集,选择有限测试用例对修改后软件测试可以减少测试周期和测试成本.提供了一个面向对象软件选择策略测试方法,对修改前软件和修改后软件创建类关系图,利用该模型进行测试,这种选择策略确保软件质量是有效,经济,安全的.

Select Strategy of Regression Testing on Object-oriented Software

Regression testing is an expensive but necessary maintenance activity performed on modified software to provide confidence that changes are correct and do not adversely affect other portions of the software. A regression test selection technique chooses, from an existing test technique for regression test selection. A regression test selection technique can save time and efforts. A new technique for regression test selection is presented, algorithms is constructed to class-related graph for program and its modified version and use these graphs to select tests that ex- ecute changed code from the original test suite. Under certain conditions the algorithms are safe, efficient, elecnomic and precise.
