Difference between webdriver.Dispose(), .Close() and .Quit()

1   webdriver.Close() - method closes the browser instance which was opened by the WebDriver. Suppose, during execution Webdriver had opened multiple browser windows. When close() method is called, it will close only the browser instance opened by it.

2   webdriver.Quit() - It closes all the browser windows that opened by the webdriver i.e. destroy the WebDriver instance. Suppose, during execution Webdriver had opened multiple browser windows. When quit() method is called, it will close all the browser windows opened by Selenium WebDriver.

3    webdriver.close() - closes the browser window on which the focus is set.

If there are more than one Browser window opened by the Selenium Automation, then the close( ) command will only close the Browser window which is having focus at that time. It wont close the remaining Browser window
