📌 What is Existing Browser Session?
An existing browser session means connecting Selenium WebDriver to a browser that is already opened manually instead of launching a new one.
🚀 Why Use This Approach?
- ✔ Save execution time
- ✔ Debug scripts faster
- ✔ Reuse logged-in session
- ✔ Avoid repetitive steps
💻 Java Example
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("debuggerAddress", "localhost:9222");
WebDriver driver = new ChromeDriver(options);
⚙️ Steps to Connect
- Open Chrome with debugging mode
- Run command: chrome.exe --remote-debugging-port=9222
- Connect Selenium using debuggerAddress
