軟件測試白盒測試用例練習(xí)題

1、白盒測試用例練習(xí)一、為以下所示的程序段設(shè)計一組測試用例，要求分別滿足語句覆蓋、判定覆蓋、條件覆蓋、判定/條件覆蓋、組合覆蓋和路徑覆蓋，并畫出相應(yīng)的程序流程圖。voidDoWork(intx,inty,intz)intk=O,j=O;if(x3)&(z5)j=x*y+10;/語句塊2j=j%3;語句塊3a將里面的判定條件和過程記錄如下:判定條件M=x3andz51、語句覆蓋測試用例輸入輸出判定M的取值判定N的取值覆蓋路徑x=4,z=5,y=8k=31,j=0TTP1(a-c-e)2、判定覆蓋pl和p4可以作為測試用例，其中pl作為取真的路徑，p4作為取反的路徑。測試用例輸入輸岀判定M的取值判定N

2、的取值覆蓋路徑x=4,z=5,y=8k=31,j=0TTP1(a-c-e)x=2,z=11,y=5k=0,j=0FFP4(a-b-d)也可以讓測試用例測試路徑P2和P3。相應(yīng)的兩組輸入數(shù)據(jù)如下:測試用例輸入輸岀判定M的取值判定N的取值覆蓋路徑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、條件覆蓋對于M:x3取真時T1，取假時F1;zv10取真時T2，取假時F2;對于N:x=4取真時T3，取假時F3;y5取真時T4,取假時F4。條件：x3,z5條件：x=10,x!=4,yv=5根據(jù)條件覆蓋的基本思路，

3、和這8個條件取值，組合測試用例如表所示測試用例輸入輸出取值條件具體取值條件覆蓋路徑x=4,z=5,y=8k=31,j=T1，T2，T3，x3,z5P1(a-c-e)0T4x=3,z=11,y=k=0,j=0F1，F(xiàn)2，F(xiàn)3，x=10,x!=4,P4(a-b-d)5F4y3,z5P1(a-c-e)0T4x=3,z=11,y=k=0,j=0F1,F2,F3，x=10,x!=4,P4(a-b-d)5F4y3,z3,z=103)x=3,z=105)x=4,y56)x=4,y58)x!=4,y=5測試用例輸入輸岀覆蓋條件取值覆蓋條件組合覆蓋路徑x=4,z=5,y=6k=23,j=1T1,T2,T3,T4
