I am currently working on automating my tests using web driver, testng, and the page factory. However, I have encountered a null pointer exception while executing the code provided below.
HomePage Page Object Class
This is the page factory class.
package POM;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class HomePage
{
WebDriver driver;
private static WebElement element = null;
public HomePage(WebDriver driver)
{
this.driver = driver;
}
public static WebElement signin(WebDriver driver)
{
element=driver.findElement(By.xpath("/html/body/div/div[1]/header/div[2]/div/div/nav/div[1]/a"));
return element;
}
public static WebElement emailCreate(WebDriver driver)
{
element=driver.findElement(By.id("email_create"));
return element;
}
public static WebElement submitCreate(WebDriver driver)
{
driver.findElement(By.id("SubmitCreate"));
return element;
}
}
This is the Test Class for executing actual tests. Test Case Class
package POM;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import POM.HomePage;
public class MyTest {
private static WebDriver driver = null;
@BeforeMethod
public void beforeMethod()
{
System.setProperty("webdriver.chrome.driver", "C:/chromedriver_win32/chromedriver.exe");
WebDriver driver=new ChromeDriver();
driver.get("http://www.automationpractice.com");
System.out.println("Hi");
driver.manage().window().maximize();
}
@Test
public void login() throws InterruptedException
{
System.out.println("login");
HomePage.signin(driver).click();
String title = driver.getTitle();
System.out.println(title);
HomePage.emailCreate(driver).sendKeys("<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="cfbaa3a4aea78fb7bfaea1b7a6a0a1e1aca0e1a6a1">[email protected]</a>");
Thread.sleep(2000);
HomePage.submitCreate(driver).click();
}
@AfterMethod
public void afterMethod()
{
driver.close();
}
}
