Load Default/Custom Chrome Profile to run tests using Selenium WebDriver

1. Download Chromedriver 2.4
2. Extract the zipped folder chromedriver_win32.zip and locate .exe file to C:/ folder

System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=C:/Users/user_name/AppData/Local/Google/Chrome/User Data");
options.addArguments("--start-maximized");
driver = new ChromeDriver(options);

If you face such error:
"org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited normally"

Then try to create a new Chrome profile and execute tests.

1| Copy the folder, 'User Data' and paste it on the same folder with different name. e.g., New User
2| Open the folder, 'New User'.
3| Rename the folder, 'Default';  so that after your test run, a new folder named, 'Default' will be created.
4| Now, replace the directory on your code with C:/Users/user_name/AppData/Local/Google/Chrome/New User
5| If you like to test the profile, then bookmark some of the sites & observe them on next run.

Note:-
IE doesn't need profile setup to run tests because they run on Server user while Firefox and Chrome works with binary.
