系统中一个程序的结构如图14-7所示:
该程序有4条不同路径,分别为L1:a→c→e;L2→a→b→d;L3:a→b→e;L4:a→c→d。小王设计了4组测试用例:
①【(1,0,3),(1,0,4)】覆盖abe;【(2,1,1),(2,1,2)】覆盖abe:
②【(2,1,1),(2,1,2)】覆盖abe;【(3,0,3),(3,0,1)】覆盖acd;
③【(2,0,4),(2,0,3)】覆盖ace;【(1,0,3),(1,0,4)】覆盖abe;
【(2,1,1),(2,1,2)】覆盖abe;【(1,1,1),(1,1,1)】覆盖abd;
④【(2,0,4),(2,0,3)】覆盖ace;【(1,1,1),(1,1,1)】覆盖abd;
【(1,1,2),(1,1,3)】覆盖abe;【(3,0,3),(3,0,1)】覆盖acd;
这4组测试用例中(5)属于判定覆盖:(6)属于条件覆盖;(7)属于路径覆盖;(8)属于条件组合覆盖。(注:该题测试用例格式为【(A,B,X)输入,(A, B,X)输出】)。

听力原文: It can get extremely noisy down here. The staff are supposed to wear ear protectors at all times but that's impossible if you need to talk to someone. The other things we have to contend with is dirt and dust. It's OK when we're not too busy but when there's a rush on there isn't time to clear up.
