Switching between tabs

Switching between tabs in same browser window

Get the current window handle and open a new tab using Ctrl + t

        driver.get("http://google.com");
        String windowHandle = driver.getWindowHandle();
        driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL +"t");

The size of the output of getWindowHandles() is 1 which means that there is one single window handle

        ArrayList tabs = new ArrayList (driver.getWindowHandles());
        System.out.println(tabs.size());
        driver.switchTo().window(tabs.get(0)); 

The control is now in the new tab

        driver.get("http://bing.com");
        //perform other operations.

Switch to the old tab using Ctrl + Tab

        driver.switchTo().window(mainWindowHandle);
        driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL +"\t");
        driver.switchTo().defaultContent();
