Headless Mode using Selenium

 Headless mode is a feature of Selenium that allows the browser to run in the background without a visible user interface. This means that the browser runs without actually opening a window, which can be useful for running automated tests or web scraping scripts that do not require any human interaction.

To run Selenium in headless mode, you need to set the "headless" option to "true" when initializing the web driver. Here is an example in Java:

import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.chrome.ChromeOptions; public class HeadlessExample { public static void main(String[] args) { // Create options object for headless mode ChromeOptions options = new ChromeOptions(); options.setHeadless(true); // Initialize Chrome driver with options WebDriver driver = new ChromeDriver(options); // Navigate to website driver.get("https://www.example.com"); // Run your tests or web scraping script here // Close the driver driver.quit(); } }

In the above example, we created an options object for Chrome driver and set the headless option to true. Then, we initialized the driver with the options and navigated to a website. Any subsequent tests or web scraping actions will run in headless mode. Finally, we closed the driver when we were done.

Note that not all browser drivers support headless mode. Chrome, Firefox, and PhantomJS are popular browser drivers that do support headless mode. Additionally, you may need to modify your test scripts or web scraping code to handle headless mode properly, such as waiting for elements to load properly before interacting with them.

Also, please make sure to have the latest version of Chrome driver executable file and add the path to it as a system property while creating the driver object.
