(1) Identify the fault : The first element of the array is not looped. "for(int i=x.length-1;i>0;i--)"should be "for(int i=x.length-1;i>=0;i--)" (2) If possible, identify a test case that does not execute the fault. ( Reachabil
问题:给定两段代码,设计fault,error,failure的测试用例. fault:即引起错误的原因,类似病因. error:类似疾病引起的内部结果. failure:类似疾病引起的症状. 代码1: public int findLast (int[] x, int y) {//Effects: If x==null throw NullPointerException// else return the index of the last element// in x that equal
给出的题目如下: 我的解答如下: For program 1:1. where i > 0 is the fault , it should be changed to i>= 0 to avoid x is just one element situation. 2.x[] ={} or x[]={n}(n is equal to any numb),for example x[] ={1}; //test: x[] = {};y =2 //expected = NullPointerExc
Software Testing 3014218128 牛菲菲 Below are two faulty programs. Each includes a test case that results in failure.Answer the following questions (in the next slide) about each program. 1. public int findLast (int[] x, int y) {//Effects: If x==null thr

记录一个小问题,重新买的linux换yum源的时候一直提示: Error: failure: repodata/repomd.xml ] No more mirrors to try. 一直说那个XML文件不存在,以为是yum源是去读取xml当中的数据然后去下载.确实自己去访问也是404.还以为是这阵子开会yum源都搞不能用了怎么.之前我用阿里用的挺好的. 搞来搞去.一恼火/yum.repos.d/目录下的文件全tmd删了.然后TMB的就可以用了.
