How to Open New Tab with Selenium WebDriver

Selenium WebDriver  tool do not have any built In API using which we can directly use to open new tab. Normally we are using CTRL + t Keys to open new tab In Browser and cltr + tab to switch between the tabs. We will use this in our selenium test case to open another tab inside a browser and switch to tab. 

Check out the Example below in details to understand how to open a new tab, how to open particular url in the new tab, how to switch between two tabs  and how to close the tabs.

public class BromiumTests {

 WebDriver driver;
 Utils util;

 @BeforeTest
 public void setUp() {
  System.setProperty("webdriver.chrome.driver", "C:\\Softwares\\chromedriver_win32\\chromedriver.exe");
  driver = new ChromeDriver();
  driver.manage().window().maximize();
  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  
 }

 
 
 @Test
 public void testOpenYoutube() {
  driver.get("https://www.youtube.com");
  
  driver.get("https://www.youtube.com/watch?v=9NXEnGiOeUU");
  driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

 }
        @Test
 public void testOpenGmail() {
  switchToNewTab();
  driver.get("http://www.gmail.com");
  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 }
       public void openNewTab() {
  ((JavascriptExecutor) driver).executeScript("window.open('about:blank','_blank');");
 }

 public void switchToNewTab() {
  openNewTab();
  String subWindowHandler = null;

  Set<String> handles = driver.getWindowHandles();
  Iterator<String> iterator = handles.iterator();
  while (iterator.hasNext()) {
   subWindowHandler = iterator.next();
  }
  driver.switchTo().window(subWindowHandler);
 }

 @AfterClass
 public void tearDown() {
  driver.quit();
 }
