Answer 1

Above question is already answered here.

1. You will need Chrome driver executable on your system. So download it from (http://www.seleniumhq.org/download/) unzip it somewere in your system. I will assume you will place it to C:\chromedriver.exe

 

2. Then you have to set it up in the system properties. Here is the Java code pasted from my Selenium project:

File file = new File("C:/chromedriver.exe");

System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());

WebDriver driver = new ChromeDriver();

 

Basically, you have to set this property before you initialize driver

 

Hope that helps
