摘　　要：在回归测试过程中,测试集的规模不断的变大增加了测试的成本。结合某种测试准则利用测试简化法对测试集中冗余的测试用例进行删除是一种有效的解决方法。但是用此方法得到的简化测试集,其错误检测能力往往被减弱。因此提出了一种新颖的测试覆盖准则,即二级变量串联覆盖准则和二级变量并联覆盖准则。这两种准则主要考虑了变量间的串、并联关系对程序的影响。用此准则与其它测试覆盖准则相组合,利用HGS测试集简化法对测试集进行选择,既简单高效又保证了最小化测试集的错误检测能力。针对文献[3]中的具体应用实例,验证了该测试覆盖准则的有效性。The arising scale of test suite adds the testing cost in regression test. With some testing coverage criteria, the testing suite reduction method is a kind of effective approach to erase those redundant test cases. However, with this method, the fault detect effectiveness of test suite is often decreased. So we presented two new test coverage criteria i. e. two-stage variable serial criteria and two-stage parallel coverage criteria. These two criteria mainly focused on the influ- ence of serial or parallel relations of variables on software. Combining this criterion with other test criteria, we simplified the test suite using HGS reduction method and maintained the fault detect effectiveness of reduced test suite highly effectively and simply. With the specific example in reference paper [3], the new testing coverage criteria were validated.
