@Test

public void f() {

g.manage().window().maximize();

g.get("Mention Ur Url");

}

@Parameters("browser")

@BeforeTest

public void beforeTest(String browser) throws Exception

{

if(browser.equalsIgnoreCase("firefox"))

{

//If no browser passed throw exception

throw new Exception("Browser is not correct");

g.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

}

@AfterTest

public void afterTest() {

g.close();

} 

XML Suite File: 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="TestSuite" parallel="tests" >

<test name="ChromeTest">

<parameter name="browser" value="Chrome" />
