Selenium Webdriver

The most significant part of the Selenium Tool Set is the Selenium WebDriver. The new update, Selenium 2.0, is compatible with the WebDriver API, which offers a programming interface that is simplified and more succinct.

With WebDriver, it is easy to use some of the supported programming languages to construct test scripts that can be executed directly on most modern web browsers.

In contrast to Selenium RC, Selenium WebDriver operates even better because it allows direct calls to web browsers. Whereasto connect with browser RC requires an RC server.

WebDriver has a Firefox driver implementation built in. You need to plug-in special drivers to your browser for other browsers to connect and run the test. WebDriver's most widely used include:

•         Opera Driver
•         Internet Explorer Driver
•         HTML Unit Driver
•         Google Chrome Driver
•         Safari Driver

JSON Wire Protocol

JSON is an open platform data sharing standard. Data structures such as objects and arrays are supported. So, writing and reading data from JSON is fast.

A communication mechanism between a server and a client to transfer data is provided by the JSON Wire Protocol. The JSON Wire Protocol serves as an industry standard for numerous REST network services.Find out all from online providers.

Selenium WebDriver- Architecture

The Selenium WebDriver API offers language-to-browser connectivity facilities.

WebDriver Architecture has four basic components:

•         Selenium Language Bindings
•         Real Browsers
•         Browser Drivers
•         JSON Wire Protocol

Browser Drivers

Selenium provides a stable connection to the browser using browser-specific drivers without revealing the internal logic of the browser's functionality.Often, the browser driver is unique to the automation language used, such as Java, C#, etc. Java Training In Delhi

The following operations are conducted internally while we run a test script using WebDriver.

•         The HTTP request is created and sent to the browser driver for each Selenium instruction.
•         The HTTP request is answered by the driver via the HTTP server.
•         The HTTP Server specifies all steps for the execution of commands that are executed on the browser.

Selenium Language Bindings

Selenium developers have built language bindings in order to support many languages. For starters, if you want to use the Java browser engine, use the Java bindings. You will import all approved language bindings from Selenium's official website (https://www.seleniumhq.org/download/#client-drivers).

Selenium WebDriverFeatures

Multiple Languages Support:The most widely used programming languages, such as C#, PHP, JavaScript, Ruby, Pearl, Javaand Python, are also provided by WebDriver. The user will then pick any of the accepted programming languages on the basis of his or her knowledge and start generating the test scripts.

Multiple Browser Support:A large range of Firefox, Chrome, Internet Explorer, Opera and several other web browsers are supported by Selenium WebDriver.Few non-conventional or unusual browsers, such as HTMLUnit, are also supported.

Speed:When compared with other Selenium Suite software, WebDriver performs better. Unlike RC, no intermediate server is needed to communicate with the browser; the tool communicates directly with the browser instead.

Simple Commands:It is quick to execute most of the commands used in Selenium WebDriver. For eg, the following commands are used to open a browser on WebDriver:

WebDriver driver = new FirefoxDriver(); (Firefox browser )

WebDriver driver = new InternetExplorerDriver(); (Internet Explorer browser)

WebDriver driver = new ChromeDriver(); (Chrome browser)

WebDriver- Methods and Classes:In automation research, WebDriver proposes different methods to deal with certain future problems.

WebDriver also helps testers to use dynamic finders to work with complex types of web components, such as checkboxes, dropdowns and warnings.
