Selenium webdriver provides two methods for closing a browser window - close() and quit(). Some people incorrectly use them interchangeably but the two methods are different. In this post, we will study the difference between the two and also see where to use them effectively.

WebDriver.close()

The close() command is used to close the current browser window having focus. In case there is only one browser open then calling close() quits the whole browser session.
Usability
It is best to use close() when we are dealing with multiple browser tabs or windows e.g. when we click on a link that opens another tab. In this case after performing required action in the new tab, if we want to close the tab we can call the driver.close() method.

// Closing the tab
webDriver.close();

WebDriver.quit()

The quit() is used to quit the whole browser session along with all the associated browser windows, tabs and pop-ups.
Usability
It is best to use quit() when we no longer want to interact with the driver object along with any associated window, tab or pop-up. Generally it is one of the last statements of the automation scripts. In case, we are working with Selenium with TestNG or JUnit, we call quit() in the @AfterSuite method of test suite. Thus, closing it at the end of whole suite.

@AfterSuite
public void tearDown() {
   webDriver.quit();
}
