Starting Chrome Browser using WebDriver(Selenium2) with example

If we would like to run our scripts on Chrome we need "chromedriver"along with the actual Chrome Browser.If you try to start the Chrome Browser with the below statement alone
WebDriver driver = new ChromeDriver();

Then you will notice below error statements

"You need to have both chromedriver and a version of chrome browser installed
@BeforeTest setUpDriver
java.lang.IllegalStateException: 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. The latest version can be downloaded from http://code.google.com/p/chromedriver/downloads/list
at com.google.common.base.Preconditions.checkState(Preconditions.java:172)
atorg.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:114)"

In our scripts if we dont specify where is chromedriver is located then we cant start chrome browser using WebDriver.

Here are steps to setup chromedriver

1.Download chromedriver from
http://code.google.com/p/chromedriver/downloads/list
2.Unzip the file .Say you downloaded it on your desktop folder named "Automation" and unzipped it then location will be like
C:\\Users\\<<User Name>>\\Desktop\\Automation\chromedriver_win_19.0.1068.0\\chromedriver.exe
3.Use the below code to start chrome
System.setProperty("webdriver.chrome.driver","C:\\Users\\<<UserName>>\\Desktop\\Automation\\chromedriver_win_19.0.1068.0\\chromedriver.exe"); 
ChromeDriver driver = new ChromeDriver();

Now you are done. :)

If you are using the TestNG framework then here is the sample code :

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class chromeDriver {
 
WebDriver  driver;

@BeforeTest
 public void setUpDriver(){
   System.setProperty("webdriver.chrome.driver",
"C:\\Users\\<>\\Desktop\\Automation\\chromedriver_win_19.0.1068.0\\chromedriver.exe");  
   driver = new ChromeDriver(); 
     }

 @Test
 public void start(){
 driver.get("http://www.google.com/"); 
   }

}
