how to create driver object
Driver class: -Driver class is public, has a private constructor and private WebDriver object which named driver, so that no object can be created outside the class. It is also an example for "singleton design pattern". -Webdriver driver is private and static. Static so it is only a single copy and shared among the class. It is private so that it is encapsulated. It has a public getter method which returns driver object (browser) based on the condition (if driver==null) as a result of launching a browser based on the info retrieved from .properties file using Configuration class get method. No setter method, so it can not be modified anyway Driver class is singleton To create a singleton class, we need to 1.Declare constructor of class as private so nobody can instantiate a WebDriver object of this class from out of it. 2.Declare a private static WebDriver object. Static is needed to make it available globally. 3.Declare a public static method(getter) with return type as object of class which should check if class is already instantiated once.
