Unit Test Example

Unit testing is very important when writing a program, and the following is the code implementation and Unit test section for the maximum value of the array and the result screenshot

1 ImportJava.util.Scanner;2  Public classTest {3      Public Static voidMain (string[] args) {4         inta[]={1,2,3,4,5,6};5Judge (Largest (a,6));6         inta2[]={9,4,0,2,5,10};7Judge (Largest (a2,6));8         int[] a3={000,-1,-88,3,000,999};9Judge (Largest (a3,6));Ten         inta4[]={}; OneJudge (Largest (a4,0)); A         int[] a5=New int[5]; -Judge (Largest (a5,5)); -          while(1>0){ theSystem.out.println ("\ n Please enter the length of the array"); -Scanner sc2=NewScanner (system.in); -             intLength=sc2.nextint (); -             inta[]=New int[length]; +System.out.println ("Please enter an array"); -Scanner sc=NewScanner (system.in); +              for(inti=0;i<length;i++) A             { ata[i]=sc.nextint (); -             } - judge (Largest (a,length));  -         } -     } -      Public Static intLargest (intList[],intlength) {     in         if(list==NULL|| Length==0){ -                 return0; to         } +         intI,max=list[0]; -          for(i=0;i<length;i++){ the             if(list[i]>max) { *max=List[i]; $             }Panax Notoginseng         } -System.out.print ("\ n" +max); the         return1; +     } A      Public Static voidJudgeinti) { the         if(i==0){ +System.out.print ("\ n array is empty! "); -         } $         Else{ $System.out.print ("is the maximum value"); -         } -     } the}

Know in

These test arrays run with the following results:
