Exciting Announcement: Selenium Automation Interview Questions Series! Starting today, I’ll be covering one Selenium automation interview question each day. Stay tuned for concise and clear answers. Day 1: How does Selenium work? Selenium automates web browsers using WebDriver, which communicates with the browser. Here’s a simple explanation of its architecture and an example: Architecture: Test Script: Written in languages like Java, Python, etc. WebDriver: Acts as a bridge between the test script and the browser. JSON Wire Protocol: Used by WebDriver to communicate with the browser driver. Browser Driver: Specific to each browser (ChromeDriver for Chrome, GeckoDriver for Firefox). Browser: Where the tests are executed. Flow: The test script sends commands to the WebDriver. WebDriver translates these commands into JSON format and sends them using the JSON Wire Protocol to the Browser Driver. The Browser Driver communicates with the browser to perform actions like clicking a button or entering text. Results are sent back in the reverse order. Got more questions you'd like me to cover? Drop them in the comments! #Selenium #AutomationTesting

4moHi Isha Chaudhary Small correction..! In Selenium 4, the W3C WebDriver protocol is the standard used for communication between Selenium and browsers. This replaces the JSON Wire Protocol, which was used in earlier versions of Selenium. Key Points: W3C WebDriver Protocol: Selenium 4 uses the W3C WebDriver standard, which is a standardized way for WebDriver to communicate with browsers. This protocol ensures better compatibility and interoperability across different browsers. It simplifies the command structure and reduces the need for browser-specific implementations. JSON Wire Protocol: This was used in previous versions of Selenium (Selenium 3 and earlier) to communicate with browsers. It was based on HTTP JSON requests and responses but was more prone to variations and inconsistencies across different browser implementations. Architecture of Selenium 4 WebDriver
