How to exit full screen (Chrome) in Selenium/Java other than using java.awt Robot class?

Question

I have an application which enters full screen after login. Manually we can exit full screen by pressing 'ESCAPE' key. I have tried pressing ESCAPE key from Selenium using Actions class:

Actions action = new Actions(driver);
action.sendKeys(Keys.ESCAPE).build().perform();

But it's not working, the browser is still remains full screen.

I have also tried Robot class:

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_ESCAPE);

This was working without headless mode but not in headless mode.

I want it to work in headless mode. Can anyone help please?

PS:- If anyone can suggest better way to key press (keyboard interaction) other than Robot class (Unfortunately Actions class is also not working).

Answer 1

driver.manage().window().maximize(); exits full screen mode.
