WebDriver is an interface and all the methods which are declared in Webdriver interface are implemented by respective driver class. But if we do upcasting,we can run the scripts in any browser . i.e running the same automation scripts in different browsers to achieve Runtime Polymorphism.
What does WebDriver driver mean?
Explanation: WebDriver is an interface that is available in Selenium jar files. driver is webDriver reference variable. New is a keyword, we use to create an instance of the class. And, FireFoxDriver() is a class already existing in Selenium.
Why do we use WebDriver driver?
Benefit of WebDriver driver = new FirefoxDriver(); Having a reference variable of type WebDriver allows us to assign the driver object to different browser specific drivers. Thus allowing multi-browser testing by assigning the driver object to any of the desired browser.
What is driver and WebDriver in Selenium?
WebDriver contributes its object-oriented API for Document Object Model (DOM) interaction and browser control. When any Automated Script is executed, for every Selenium command, HTTP Request is created and sent to browser to driver. The browser driver uses a HTTP Server for getting HTTP Requests.
Why do we use WebDriver driver?
Benefit of WebDriver driver = new FirefoxDriver(); Having a reference variable of type WebDriver allows us to assign the driver object to different browser specific drivers. Thus allowing multi-browser testing by assigning the driver object to any of the desired browser.
What is difference between ChromeDriver and WebDriver?
WebDriver is an open source tool for automated testing of web apps across many browsers. It provides capabilities for navigating to web pages, user input, JavaScript execution, and many more. ChromeDriver is a standalone server which implements WebDriver’s wire protocol for Chromium.
Why is WebDriver an interface?
WebDriver is a remote control interface that enables introspection and control of user agents (browsers). The methods in this interface fall into three categories: Control of the browser itself. Selection of WebElement s.
Why do we use WebDriver instead of ChromeDriver?
Show activity on this post. Then only methods defined in the ChromeDriver class will be exposed. So we are upcasting it to the highest level which is the WebDriver interface so that all methods in WebDriver interface, and overridden in RemoteWebDriver, and ChromeDriver class are available in the object instance.
Can we use ChromeDriver instead of WebDriver?
If we want to run our automation scripts on the local machine’s browser then we can use any class (such as Firefoxdriver, iedriver, chromedriver, htmlunitdriver) except RemoteWebDriver. WebDriver will start up a web browser on the computer where the code instantiates it.
What is POM in testing?
Page Object Model, also known as POM, is a design pattern in Selenium that creates an object repository for storing all web elements. It is useful in reducing code duplication and improves test case maintenance.
How many drivers are there in Selenium?
There are four basic components of WebDriver Architecture: Selenium Language Bindings. JSON Wire Protocol. Browser Drivers.
Where is ChromeDriver located?
Go to the terminal and type the command: sudo nano /etc/paths. Enter the password. At the bottom of the file, add the path of your ChromeDriver. Type Y to save.
What is cucumber in Selenium?
Cucumber is a behavior-driven development tool that can be used with Selenium (or Appium). Selenium is preferred by technical teams (SDETs/programmers). Cucumber is typically preferred by non-technical teams (business stakeholders and testers). Selenium is used for automated UI testing.
What is the difference between WebDriver and WebElement?
Anything that is present on the web page is a WebElement such as text box, button, etc. WebElement represents an HTML element. Selenium WebDriver encapsulates a simple form element as an object of the WebElement. It basically represents a DOM element and all the HTML documents are made up by these HTML elements.
What is WebDriver manager in Selenium?
WebDriverManager is an open-source Java library that carries out the management (i.e., download, setup, and maintenance) of the drivers required by Selenium WebDriver (e.g., chromedriver, geckodriver, msedgedriver, etc.) in a fully automated manner.

Is Selenium WebDriver an interface?
Selenium WebDriver is an interface that defines a set of methods. However, implementation is provided by the browser specific classes. Some of the implementation classes are AndroidDriver , ChromeDriver , FirefoxDriver , InternetExplorerDriver , IPhoneDriver , SafariDriver etc.
How many interfaces are there in Selenium?
The webElement interface extends two other interfaces like SearchContext and TakesScreenshot interfaces. the webElement interface has so many useful methods that are frequently used during the automation. those methods like clear(), click(), getText(), submit() etc.
What is XPath in Selenium?
What is XPath in Selenium? XPath is a technique in Selenium to navigate through the HTML structure of a page. XPath enables testers to navigate through the XML structure of any document, and this can be used on both HTML and XML documents.
What is the base class of WebDriver?
Hey Prashant, in Selenium Base class is the main class which takes care of Browser setup, loading configuration file and other reusable methods like screenshot, handling sync issues and many more. With base class you can avoid code duplication and can reuse the code as much you want.
