@DataProvider Annotation

               How to execute a test case with  multiple sets user inputs using  using the Robot objects.The beauty of Selenium Web Driver Automation provides two types. They are:
1.From Excel Sheet
2.@DataproviderAnnotation

    Both of them are having it's own Pro's and Con's.  I have provided the Sample code by using @Dataprovider Annotation .I will describe Writing and retrieving data from the Excel sheet in my next Post.


package TestNG;

import java.awt.AWTException;
import java.awt.Robot;
import java.util.concurrent.TimeUnit;
import junit.framework.AssertionFailedError;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class LoginTestNg {

private WebDriver driver;

private String baseUrl;

private Robot robot;

@BeforeMethod

public void setUp() throws Exception {

driver =new FirefoxDriver();

baseUrl = "https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=http://mail.google.com/mail/&scc=1&ltmpl=default&ltmplcache=2&emr=1";

driver.manage().window().maximize();

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

System.out.println("@BeforeMethod - setUp");
}
////naming the inputs which  we can describe by Dataprovider Annotation
@DataProvider(name = "DP1")

public Object[][] createData() {

Object[][] retObjArr={{"abcdefgh","acdfe45l@"},                ///providing the inputs in which username and password required to login.

{" ","jjjfmfmldfi"},
                             
                                {"abishek","jksdhkhsdd"},

{" "," "},
                             
                                {"abhishekmucherla5",""}};

return(retObjArr);
}

/////////////naming the Dataprovider annotation in @test annotation

@Test (dataProvider = "DP1")

public void logiin(String username, String password) throws Exception{

driver.get(baseUrl + "/");

driver.findElement(By.id("Email")).sendKeys(username);


driver.findElement(By.id("Passwd")).sendKeys(password);

try {

robot = new Robot();

robot.keyPress(java.awt.event.KeyEvent.VK_ENTER);


} catch (AWTException e) {

assert(e.getMessage().isEmpty()): AssertionFailedError.class.desiredAssertionStatus();

}

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

}

@AfterMethod

public void tearDown() throws Exception {

driver.quit();

System.out.println("@AfterMethod - tearDown");

}
