Software QA/Testing:

Suppose you want to perform basic path testing for the Java program given that calculates the Hotel Suites occupancy. These are located on floors 10-16. There is no 13th floor.

Draw the control flow graph to perform basic path testing.

import java.util.Scanner;
import java.text.*;
public class hotelOccupancy
{
public void calcRate()
{
   final int
       SUITES_PER_FLOOR = 20,   // Number of suites per floor
       MIN_FLOOR = 10,          // Lowest floor of suite units
       MAX_FLOOR = 16,          // Highest floor of suite units
      
      

       TOTAL_SUITES = (MAX_FLOOR - MIN_FLOOR) * SUITES_PER_FLOOR;
     
        Scanner scan = new Scanner(System.in);
        DecimalFormat fmt = new DecimalFormat();

   int occupied,                // Number of occupied suites on the floor
       totalOccupied = 0;       // Total number of occupied suites
  
   double occupancyRate;        // % of the suites that are occupied

   // Get and validate occupancy information for each floor
   System.out.println("Enter the number of occupied suites on each of the following floors.n");

   for (int floor = MIN_FLOOR; floor <= MAX_FLOOR; floor++)
   {
       if (floor == 13)
            continue;          // Skip thirteenth floor
      
       System.out.println("nFloor " + floor+ ": ");
       occupied=scan.nextInt();                                      
       while (occupied < 0 && occupied > SUITES_PER_FLOOR)
       {
           System.out.println("nThe number of occupied suites must be between 0 and " + SUITES_PER_FLOOR );
           System.out.println("n Re-enter the number of occupied suites on floor " + floor + ": ");
           occupied = scan.nextInt();
       }
    
       // Add occupied suites on this floor to the total
       totalOccupied += occupied;
   }
  
   // Compute occupancy rate in % form
   occupancyRate = 100* totalOccupied / TOTAL_SUITES;  

   // Display results
  
   System.out.println("nnThe hotel has a total of " + TOTAL_SUITES + " suites.n");
   System.out.println(totalOccupied+ " are currently occupied.n");
   System.out.println("This is an occupancy rate of " + fmt.format(occupancyRate)+ "% n");   
}
}
