object oriented testing code example

Example 1: object-oriented programming

class Person {
 void walk() {
  System.out.println(“Can Run….”);
 }
}
class Employee extends Person {
 void walk() {
  System.out.println(“Running Fast…”);
 }
 public static void main(String arg[]) {
  Person p = new Employee(); //upcasting
  p.walk();
 }
}

Example 2: object oriented programming

//	OOP is a programming paradigm found in many languages today.
//	Generally, an object is an instance of a Class.
//	Here's a Java example:
public class Car
{
	private double speed;
  	
  	public Car(double initialSpeed)	//	Constructor, most common way to initialize objects of a class.
    {
    	speed = initialSpeed;
    }
  
  	//	Accessor methods, aka getters
  	public double getSpeed()
    {
		return speed;
     	//	This is an example of encapsulation, where
      	//	methods are used to hide the implementation details
		//	and ensure the programmer can't modify things they shouldn't be able to.
    }
  
  	public void accelerate()
    {
		speed++;
    }
  
  	public void slowDown()
    {
    	speed--;
    }
}

Example 3: object oriented testing

Well-engineered object-oriented design can
make it easier to trace from code to internal
design to functional design to requirements.
While there will be little affect on black box 
testing (where an understanding of the internal
design of the application is unnecessary), 
white-box testing can be oriented to the
application's objects. If the application was
well-designed this can simplify test design.
