//Setting the system property to use chrome exe
System.setProperty("webdriver.chrome.driver","C:\\Downloads\\Softwares\\chromedriver_win32\\chromedriver.exe" );
driver=new ChromeDriver();
driver.navigate().to("http://demosite.center/wordpress/wp-login.php");
Thread.sleep(5000);
driver.findElement(By.id("user_login")).sendKeys(Username);
driver.findElement(By.id("user_pass")).sendKeys(Password);
driver.findElement(By.xpath(".//*[#id='wp-submit']")).click();
}
//this is after method for driver quit
#AfterMethod
public void teardown(){
driver.quit();
}
//this is data provider
#DataProvider(name="wordpressdata")
public Object[][] passdata(){
Object[][] data = new Object[3][2];
data[0][0] = "Admin";
data[0][1] = "demo123";
data[1][0] = "Admin";
data[1][1] = "demo23";
