what is webdriver in selenium
WebDriver:
WebDriver object represents the browser in Selenium.
Using this object you can control the Web browser.
It is an interface of the org.openqa.selenium.* package.
Upon instantiating the implementations of this class
the browser will be launched.
FirefoxDrive, ChromeDriver,
InternetExplorerDriver, SafariDriver, OperaDriver,
HtmlUnitDriver, RemoteWebDriver are few
implementations of the WebDriver Interface.driver object in selenium
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.what is webdriver in selenium
