Below is the java program to guess the number of Apples Tom has. Tom would type higher if he has higher number of apples than the guessed number and lower if it is lower. He will respond with none when the number guessed is correct. My task is to write a JUnit test case for this program. Since based on the user input the guessed number is either decremented or incremented until we reach the actual value it confuses me as to how to write a JUnit test case for this program
public static void main(String args[]){
System.out.println("Guess the number of Apples Tom has");
Scanner sc= new Scanner(System.in);
int number=sc.nextInt();
System.out.println("Tom, is it higher or lower?")
String higherOrLower=sc.nextLine();
while(true){
number= getValue(higherOrLower,number);
System.out.println("Tom, is it higher or lower?")
higherOrLower=sc.nextLine();
if(higherOrLower.equalsIgnoreCase("none")) {
break;
}
}
}
public static int getValue(String i,int j){
if(i.equalsIgnoreCase("lower") {
j--;
return j;
} else if(i.equalsIgnoreCase("higher")) {
j++;
return j;
} else {
return j;
}
}
