title: Good practice to change a method signature
body: <p>I have a situation where I declare a method say</p>
  
  <pre><code>public String getData(WebDriver driver, int iRowNumber)
  </code></pre>
  
  <p>I am calling this method from a number of other test case methods. Now I feel the necessity to change the number of parameters and include a third parameter. It is obviously going to throw error in all the previous test case methods. How do I handle this situation? I don't want to create another method with the same name and different number of arguments (Polymorphism) as I have to use the modified method in the previous test methods as well. </p>
  
  <p>Is there a way by which I can take care of this?</p>
