Overview: Selenium Webdriver
Selenium Webdriver is a free and open-source API suite that has the ability to test web applications. Selenium Webdriver is a device for automating the testing of web applications to ensure that they function as expected. It works well with most browsers, including Firefox, Chrome, Safari, and Internet Explorer. It also enables cross-browser testing.
Before going into the depth of Selenium Webdriver, let us quickly have a look at the topics we will be discussing:

Know more about Selenium Webdriver
- A web page is composed of various web elements such as text boxes, checkboxes, and buttons. The task of web automation testing is to optimize the tasks that need to be performed on those web elements. Selenium WebDriver is a well-known web-based automation testing framework that is primarily used to automate Web UI testing tasks.
- Selenium WebDriver does not directly interact with web elements on a page. A browser-specific Selenium WebDriver connects the test script to the web browser. Selenium WebDriver is the main element that interacts with the web browser. Selenium locators are used to locate elements on a page so that appropriate interaction methods can be used.
- The majority of programming languages used by developers and testers, including Python, Java, C#, Ruby, and others, are supported by Selenium WebDriver. It works with popular operating systems such as Windows, Mac OS, Linux, and Solaris.
- Mozilla Firefox is the default web browser for Selenium WebDriver.

The Architecture of Selenium Webdriver
Selenium WebDriver APIs are used to communicate between programming languages and web browsers.
The Selenium WebDriver architecture consists of the following elements:
- Browser Drivers
- JSON Wire Protocol
- Selenium Client Libraries
Browser drivers are primarily responsible for interacting with the associated web browser. Each browser has its own browser driver, which must be installed on the machine that will be used for automation testing.

Each web browser has its own browser driver, such as Chrome, Firefox, and Internet Explorer (or HTTP Server).
- Selenium Client Libraries
Developers can use Selenium to perform automation testing with popular programming languages, as previously stated. This multi-language support is enabled by Selenium Client Libraries.
Selenium Python tutorial will teach you how to use Selenium with Python. Python language bindings would be required as a result. Language drivers for programming languages such as Python can be obtained from the Selenium website.
Selenium is compatible with numerous browsers, including Chrome, Firefox, Internet Explorer, and Microsoft Edge. The framework is incompatible with browsers that lack a browser driver.

Popular Commands and Methods used in Selenium Webdriver
1. Acquiring a homepage
2. Reload or refresh a website
3. Locating and transmitting forms and user input
4. Executing the Click event
Use the click() method to perform a click operation on any web element.
5. Remove User Input
Use the clear() method to remove all user inputs from the text.
6. Transitioning Between Frames
7. Data Extraction from Any Web Element
In order to perform assertions and debugging, we occasionally need to retrieve the text written over a web element. The getText() method is used to retrieve data written over any web element.
8. Using the Browser’s History to go back in time
9. Navigating the Browser History to move forward
10. Changing Windows
Difference between Selenium RC and Webdriver
|Selenium RC||Selenium Webdriver |
|Selenium RC is a Weak API.||WebDriver is a Powerful API.|
|Command-specific usage||There were no commands used.|
|There is no support for third-party APIs and software.||Third-party API and software support|
|RC server frequently fails.||No server, no miss-firing|
|Excessive test suite management is a challenge.||It is simple to manage large test suites.|
|Can run Selenium RC scripts||The Selenium WebDriver script cannot be run.|
|The RC Server must be started.||There is no requirement to launch a server.|
|Poor report generation||Can generate technical and managerial reports|
|Uses the command line prompt||There is no use of the command-line prompt.|

Advantages of Selenium Webdriver
To begin with, the fact that Selenium WebDriver is open source is a significant benefit. It includes all of QTP’s features and more, and it is completely free. It can be downloaded directly from the official website, and because it is community-based, there is also support for the tool.
- Compatibility with a Variety of Operating Systems
One of the major advantages of Selenium Webdriver for automation testing with Selenium over previous versions is that it is compatible with a wide range of operating systems, including Linux, UNIX, Mac, and Windows. Using their solution suite, you can create a customised testing suite that can be used on any platform. WebDriver lets you create and run test cases on Windows and Linux.
- Cross-Device Testing support
Another significant benefit of Selenium WebDriver automation testing is cross-device testing support. Automated test cases for testing on iPhones, Blackberries, and Android devices can now be written, assisting with cross-device issues.
