Using the PageFactory class for exposing an operation on a page

In the previous recipe, we created the BmiCalcPage class, which provides elements from the BMI Calculator page to the test. Along with elements, we define operations or behaviors on a page. In the BMI Calculator application, we are calculating the BMI by entering height and weight values. We can create an operation named calculateBmi and call it directly in a test, instead of calling individual elements and operations.

In this recipe, let's refine the BmiCalcPage class. And instead of elements, let's provide the operations that are supported on the page, and some common properties. We will also move the WebDriver instance of the test to the BmiCalcPage class to make the test generic.

Getting ready

Identify operations that will be required in a test and can be exposed from a page. This recipe uses the BmiCalcPage class created in the previous recipe.
