What is Selenium WebDriver in Java?

In this article we will explain what Selenium WebDriver is in java in terms of an open-source testing tool.

We'll also go over its functions and benefits as a Java IDE. The information presented here will be enough to start using Selenium WebDriver in production-level applications. We recommend you read our post on Selenium best practices.

To fully grasp Selenium WebDriver functionality, you need to understand some terminology of different test elements in selenium driver. In programming language - there are 3 major types of elements: Elements : This type contains some web page features like buttons, links and input fields, text fields and dropdowns. : This type contains some web page features like buttons, links and input fields, text fields and dropdowns. Actions : This type executes actions on a selected element. For example, we can change or click a button on a website.

: This type executes actions on a selected element. Assertions: Assertions determine whether an element property or action belongs to a given condition. For example, it's determined whether a textbox is empty.

What is Selenium WebDriver? It is a tool for executing scripts in your browsers/drivers (automated tests). It provides a client-side API for communicating with a remote machine running a browser to carry out operations in real-time asynchronously. To clarify, Selenium WebDriver executes in a browser - it doesn't have anything to do with a 'driver' but acts as a connector between browsers and the script. We'll cover Selenium WebDriver's role in developing websites. Firstly, it is a good way to automate tasks that are repetitive and need to be carried out for many sites, such as adding new elements to a page, deleting a certain row from a table, changing a text in a given element etc.

As soon as an error occurs in your application, it might break it and then you cannot fix it anymore. The only way out is to create a script of those tasks and then automatically check every instance of an error you find.

For this reason, developers created a library of tools to assist writing these scripts. Such as Selenium.

Is WebDriver a class or interface?

I understand that WebDriver is a java class.

But is it a class and not an interface? The class is part of the Selenium project. I have looked at the source code of other projects in the Selenium project, such as WebDriver.java and iav. Neither of them have interfaces.

WebDriver.java has an interface called IWebDriver which has just a single method called public void quit(). Source: All the classes in the selenium.jar file (as well as iav.jar, which you mentioned) are Java classes that follow the Java naming conventions. They do not have interfaces, but they do extend the abstract class AbstractWebDriver which does have an interface.

The classes in selenium.jar should not be used directly because they are provided by the Selenium project. If you want to build your own solution using selenium, you will probably need to look into how to obtain the jar files from the official release, so you can modify them to your needs.

What are the 4 major components of Selenium WebDriver architecture?

The core functionality provided by Selenium WebDriver includes the WebDriver JavaScript bindings, the WebDriver C# bindings, a collection of test drivers and integration adapters.

B: Each of these provides a particular functionality and is responsible for different parts of the WebDriver architecture. C: The core components include the support for browser-specific features and capabilities like cookies, navigation history, cookies and storage, page refactoring, user agent detection, and more. It can be easily extended for additional features in the form of adapters and test drivers.

D: The different classes that comprise the Selenium WebDriver provide a unified API to handle both functional and non-functional testing. These classes are divided into 3 groups as mentioned below: The WebDriver core classesThese include classes such as the FirefoxDriver class which provides the API required for the Firefox browser. The Browser-related classesThe classes are responsible for handling the browser-specific features. These classes include WebBrowser, WebElement and WebElementProxy.

The Generic Selenium classesThe most essential classes that can be used for both functional and non-functional testing. These include classes like Assertions, HtmlAgilityPack, Page Objects, SeleniumWebElement and WebDriver.

How does the Selenium WebDriver perform? As discussed earlier, the Selenium WebDriver is an automation framework and has been designed in a way to work well on multiple browsers (IE, Firefox, Chrome, Opera, Safari and mobile devices). B: Selenium WebDriver works best when web applications have a lot of JavaScript-based functionalities. It can automate the UI, and perform page-refactor and data-binding, but it cannot perform data-driven automation. However, it does give you an accurate automation of the complete browser-specific functionalities.

C: Selenium WebDriver also supports all the web-related API functions of the browser and makes automated test cases easy to write. It has been created in such a way that it takes care of the cross-browser compatibility and can run without any configuration.

D: In functional testing, Selenium WebDriver is perfect for writing tests that contain browser-specific functionalities. For example, if you need to write a test to verify the search box.
