Selenium WebDriver Architecture
The Selenium WebDriver Architecture has several components that work together to automate the web browsers.
1. Selenium Client Libraries:
- Selenium supports various programming languages such as Java, Python, C#, Ruby, and more. These libraries provide bindings or APIs that allow you to interact with Selenium and control the browser using the chosen programming language.
- For example, if you are using Java, you would use the Selenium Java client library, and if you are using Python, you would use the Selenium Python client library.
2. JSON Wire Protocol:
- JSON Wire Protocol is a RESTful web service that acts as a communication bridge between the Selenium Client Libraries and the Browser Drivers.
- It defines a standard way for sending commands to the browser and receiving responses. These commands include actions like clicking a button, filling a form, navigating to a URL, etc.
- The protocol uses JSON (JavaScript Object Notation) as the data interchange format for communication between the client and the server (browser).
3. Browser Drivers:
- Browser Drivers are executable files or libraries specific to each browser (ChromeDriver for Chrome, GeckoDriver for Firefox, etc.).
- They act as intermediaries between the Selenium Client Libraries and the actual browsers. The client libraries communicate with the browser drivers, and the drivers, in turn, control the respective browsers.
- The browser drivers interpret the commands from the Selenium Client Libraries and convert them into browser-specific actions. They also send information back to the client libraries about the status of the commands executed.
4. Real Browsers:
- Real Browsers are the actual web browsers like Chrome, Firefox, Safari, etc.
- The browser drivers launch and control these real browsers based on the commands received from the Selenium Client Libraries. The browser drivers establish a communication channel with the browsers to automate user interactions.
- The real browsers execute the commands, perform actions on web pages, and return the results to the browser drivers, which then pass the information back to the Selenium Client Libraries.
Introduction to Selenium WebDriver – w3wiki
Selenium WebDriver is a powerful Automation tool widely used for web application testing. It provides a programming interface to interact with web browsers, allowing users to automate browser actions, navigate web pages, and perform functional testing. With support for multiple programming languages such as Python, Java, and JavaScript, Selenium WebDriver facilitates cross-browser and cross-platform testing, making it an essential tool for software developers and quality assurance professionals. In this article, we will explore the in-depth understanding of Selenium Webdriver.
