I am new to Selenium and while running the below script I am getting null pointer exception and test stops running as soon as the site called loads. I am unable to understand the reason for exception.
The code is as given below:
package TestNGPackage;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.support.ui.*;
import org.openqa.selenium.firefox.*;
import org.openqa.selenium.*;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeTest;
public class ParameterizationTest {
WebDriver driver;
@Test(dataProvider="getdata")
public void Login(String Username, String Password)
{
//WebDriverWait wait= new WebDriverWait(driver,60);
//WebElement username= wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("username")));
WebElement username=driver.findElement(By.id("username"));
WebElement password= driver.findElement(By.id("password"));
username.sendKeys(Username);
password.sendKeys(Password);
WebElement SignIn= driver.findElement(By.tagName("button"));
String text = SignIn.getText();
if (text.equalsIgnoreCase("sign in")) {
// sign in btn
SignIn.submit();
}
}
@DataProvider(name="getdata")
public Object[][] testgetdata()
{
Object[][] data = new Object[3][2];
//row1
data[0][0]="[email protected]";
data[0][1]="welcome23";
//row2
data[1][0]="[email protected]";
data[1][1]="welcome23";
//row3
data[2][0]="[email protected]";
data[2][1]="welcome23";
return data;
}
@BeforeMethod
public void beforeTest() {
WebDriver driver = new FirefoxDriver();
driver.get("http://52.25.202.63/illweb/");
// driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@AfterMethod
public void AfterTest() {
//driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
WebElement logout = driver.findElement(By.linkText("Logout"));
logout.click();
//driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.close();
}
}
I am getting the following error:
