WebDriver driver = new FirefoxDriver() (Firefox browser ) For instance, to launch a browser in WebDriver following commands are used:

Simple Commands: Most of the commands used in Selenium WebDriver are easy to implement.

Unlike RC, it doesn't require any intermediate server to communicate with the browser rather the tool directly communicates with the browser.

Speed: WebDriver performs faster as compared to other tools of Selenium Suite.

Thus, the user can choose any one of the supported programming language based on his/her competency and start building the test scripts.

Multiple Languages Support: WebDriver also supports most of the commonly used programming languages like Java, C#, JavaScript, PHP, Ruby, Pearl and Python.

It also supports some of the non-conventional or rare browsers like HTMLUnit.

Multiple Browser Support: Selenium WebDriver supports a diverse range of web browsers such as Firefox, Chrome, Internet Explorer, Opera and many more.

Some of the most important features of Selenium WebDriver are:

Execution status is sent back to HTTP Server which is subsequently sent back to automation script.īrowsers supported by Selenium WebDriver:.

HTTP Server decides all the steps to perform instructions which are executed on browser.

The driver receives the HTTP request through HTTP server.

HTTP request is generated and sent to the browser driver for each Selenium command.

When we execute a test script using WebDriver, the following operations are performed internally. The browser driver is also specific to the language used for automation such as Java, C#, etc. Selenium uses drivers, specific to each browser in order to establish a secure connection with the browser without revealing the internal logic of browser's functionality.

To learn more about Web Services, visit Browser Drivers JSON Wire Protocol serves as an industry standard for various REST web services. JSON Wire Protocol provides a transport mechanism to transfer data between a server and a client. So, it is easy to write and read data from JSON. It supports data structures like object and array.

JSON (JavaScript Object Notation) is an open standard for exchanging data on web. All the supported language bindings can be downloaded from the official website () of Selenium. For instance, if you want to use the browser driver in java, use the java bindings. Selenium developers have built language bindings/Selenium Client Libraries in order to support multiple languages. Selenium Language Bindings / Selenium Client Libraries There are four basic components of WebDriver Architecture: The following image shows the architectural representation of Selenium WebDriver. Selenium WebDriver API provides communication facility between languages and browsers. HTML Unit Driver (a special headless driver).For other browsers, you need to plug-in their browser specific drivers to communicate and run the test. WebDriver has a built-in implementation of Firefox driver (Gecko Driver). RC on the other hand needs an RC server to interact with the browser. Selenium WebDriver performs much faster as compared to Selenium RC because it makes direct calls to the web browsers. You can refer to the links given below to learn basic as well as advance concepts of Java and C#: For this tutorial, we are using Selenium with java. Currently, Selenium Web driver is most popular with Java and C#. Languages supported by WebDriver include C#, Java, Perl, PHP, Python and Ruby.īefore learning the concepts of Selenium WebDriver, you should be well versed with any of the supported programming languages. In WebDriver, test scripts can be developed using any of the supported programming languages and can be run directly in most modern web browsers. However, with the release of Selenium v3, RC has been deprecated and moved to legacy package.

The initial version of Selenium i.e Selenium v1 consisted of only IDE, RC and Grid. Selenium WebDriver was first introduced as a part of Selenium v2.0. The following image will give you a fair understanding of Selenium components and the Test Automation Tools. The latest release "Selenium 2.0" is integrated with WebDriver API which provides a simpler and more concise programming interface. Selenium WebDriver is the most important component of Selenium Tool's Suite.
