I had tried to run below JUnit (Selenium WebDriver) test case to open Google in Chrome browser, but it is failing with error message as 

> 
> "The path to the ChromeDriver executable must be set by the
>  webdriver.chrome.driver system property; for more information, see
>  <http://code.google.com/p/selenium/wiki/ChromeDriver>."
> 
> 
> 

As specified in that website, I downloaded ChromeDriver.exe but don't know, 
Which ***PATH*** should I place that? or 
How to set ChromeDriver path in webdriver.chrome.driver?

Please Advise. 

My JUnit test case (changed the Firefox Driver to Chrome Driver): 

```
import org.junit.*;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.*;
public class Chrome_Open_Google {
    private WebDriver driver;
    private String baseUrl;
    @Test
    public void Test_Google_Chrome() throws Exception {
        driver = new ChromeDriver();
        baseUrl = "http://www.google.co.uk/";
        driver.get(baseUrl);
    }
    @After
    public void tearDown() throws Exception {
        driver.quit();
    }
}

```
