白盒测试用例练习一、为以下所示的程序段设计一组测试用例，要求分别满足语句覆盖、判定覆盖、条件覆盖、判定/条件覆盖、组合覆盖和路径覆盖，并画出相应的程序流程图。voidDoWork(intx,inty,intz){intk=0,j=0;if((x>3)&&(z<10)){k=x*y-1;j=sqrt(k);//语句块1}if((x==4)||(y>5)){j=x*y+10;}//语句块2j=j%3;//语句块3}由这个流程图可以看出，该程序模块有4条不同的路径:P1:(a-c-e)P2:(a-c-d)\nP3:(a-b-e)P4:(a-b-d)将里面的判定条件和过程记录如下:判定条件七{x>3andz<10}判定条件N={x=4ory>5}1、语句覆盖测试用例输入输出判定M的取值判定N的取值覆盖路径x=4,z=5,y=8k=31,j=0TTP1(a-c-e)2、判定覆盖pl和p4可以作为测试用例，其中pl作为取真的路径，p4作为取反的路径。测试用例输入输出判定M的取值判定N的取值覆盖路径x=4,z=5,y=8k=31,j=0TTP1(a-c-e)x=2,z=11,y=5k=0,j=0FFP4(a-b-d)也可以让测试用例测试路径P2和P3。相应的两组输入数据如下:测试用例输入输出判定M的取值判定N的取值覆盖路径x=5,z=5,y=4k=19,j=sqrt(19)%3TFP2(a-c-d)x=4,z=11,y=6k=0,j=1FTP3(a-b-e)3、条件覆盖对于Mx>3取真时T1,取假时F1;z<10取真时T2,取假时F2;对于N:x=4取真时T3,取假时F3;y>5取真时T4,取假时F4。条件：x>3,z<10,x=4,y>5条件：x<=3,z>=10,x!=4,y<=5根据条件覆盖的基本思路，和这8个条件取值，组合测试用例如表所示测试用例输入输出取值条件具体取值条件覆盖路径x=4,z=5,y=8k=31,j=0T1,T2,T3,T4x>3,z<10,x=4,y>5P1(a-c-e)x=3,z=11,y=5k=0,j=0F1,F2,F3,F4x<=3,z>=10,x!=4,y<二5P4(a-b-d)\n4、判定/条件覆盖测试用例输入输出取值条件具体取值条件覆盖路径x=4,z=5,y=8k=31,j=0T1,T2,T3,T4x>3,z<10,x=4,y>5P1(a-c-e)x=3,z=11,y=5k=0,j=0F1,F2,F3,F4x<=3,z>=10,x!=4,y<=5P4(a-b-d)5、组合覆盖条件组合1)x>3,z<102)x>3,z>=103)x<=3,z<104)x<=3,z>=105)x=4,y>56)x=4,y<=57)x!=4,y>58)x!=4,y<=5测试用例输入输出覆盖条件取值覆盖条件组合覆盖路径x=4,z=5,y=6k=23,j=1T1,T2,T3,T41,5P1(a-c-e)x=4,z=10,y=5k=0,j=0T1,F2,T3,F42,6P2(a-c-d)x=3,z=5,y=6k=14j=1F1,T2,F3,T43,7P3(a-b-e)z=3,z=10,y=5k=0,j=2F1,F2,F3,F44,8P4(a-b-d)6、路径覆盖测试用例输入输出覆盖条件取值覆盖条件组合覆盖路径x=4,z=5,y=8k=31,j=0T1,T2,T3,T41,5P1(a-c-e)x=5,z=5,y=4k=19,j=sqrt(19)%3T1,T2,F3,F41,8P2(a-c-d)x=4,z=11,y=6k=0,j=1T1,F2,T3,T42,5；P3(a-b-e)x=2,z=11,y=5k=0,j=0F1,F2,F3,F44,8P4(a-b-d)二、冒泡法排序:#includemain(){inti,j,temp;inta[10];for(i=0;i<10;i++)scanf("%d,",&a[i]);for(j=0;j<=9;j++){for(i=0;i<10-j;i++)if(a[i]>a[i+1]){temp=a[i];a[i]=a[i+1]；a[i+1]=temp;}}for(i=0;i<10;i++)printf("%5d,",a[i]);printf("\n");\n}2、程序流程图37\n3白盒测试:3.1语句覆盖测试用例测试输入覆盖对象测试结果I=0,j=01,4,3,2,5,7,6,8,9,11124,5,6,3,71,2,3,4,5,6,7,8,9,113.2判定覆盖测试用例测试输入覆盖对象测试结果I=0,j=01,4,3,2,5,7,6,8,9,111,2,6,7,8,9,4,5,31,2,3,4,5,6,7,8,9,113.3条件覆盖测试用例测试输入覆盖对象测试结果I=0,j=01,4,3,2,5,7,6,8,9,111,2,6,7,8,9,4,5,31,2,3,4,5,6,7,8,9,113.4路径覆盖测试用例测试输入覆盖对象测试结果I=0,j=01,4,3,2,5,7,6,8,9,111,2,6,7,8,9,4,5,31,2,3,4,5,6,7,8,9,11
