1. Title Description:

The construction program is: • Cannot trigger fault. • Triggers fault, but does not trigger error. • Trigger error, but cannot produce failure

The Other Side blog address: http://www.cnblogs.com/tripoon/each other contribution than the column: 1:1 photos: 3.Fault static error, Failure external error, Error internal errors 4. Code: Program 1: The number of strings that cannot be divisible by 2

 Packagetest1;ImportJava.util.Scanner; Public classTest1 {/**     * @paramargs*/     Public Static voidMain (string[] args) {//TODO auto-generated Method StubScanner Input=NewScanner (system.in); System.out.print ("Please enter the number of tests to be tested: n="); intn=Input.nextint (); System.out.println ("Please enter the number to be tested:"); int[] num=New int[n]; intm;  for(inti=0;i<n;i++) {System.out.print ("num[" +i+ "]="); M=Input.nextint (); Num[i]=m; //Input.next ();        }//for (int i=0;i<n;i++) {//System.out.print ("num[" +i+ "]=" +num[i]+ ",");//        }//System.out.print ("Number not divisible by 2:" +Iszhengchu (num)); }         Public Static intIszhengchu (int[] num) {        intSum=0;  for(inti=0;i<num.length;i++){            if(num[i]%2==0){                 Break; } Sum++; }                returnsum; }}

(1) Fault: The break should be changed to continue

(2) An execution of fault produced an error, but did not cause failure

When the input value is num={1,3,2}, the expectation is: 2, the result is: 2

(3) Execute fault, but do not return the wrong value

When the input value is num={1,3,5}, the expectation is: 3, the result is: 3

(4) Do not perform fault

When input value num={};

The program will directly access invalid memory causing the program to hang out

5. Summary

Understand the difference between fault &failure &error three bugs in software testing and contact!
