Page Object Pattern | Selenium - Part I


Page Object Pattern is a good approach of implementing Automation tests. It is a language neutral pattern for representing a complete page or portion of a page in an Object Oriented manner. Pattern is a page object, which encapsulates the behavior of the page in an Object oriented manner. It need some programming skills too.

Why Page Object?

1| Maintenance
2| Readability of scripts
3| Separation of Concerns


Page Object Pattern | Page Factory

Lets start with an example using Google.com

SCENARIO 
1| Open URL
2| Search google
3| Assert page title



TEST CLASS | TC.java


package packagename;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class TC {
 private WebDriver driver;
 public ASSERT Task; 

  @BeforeTest
 public void setUp() throws Exception {
  System.out.println("Instantiating Firefox Driver");
  driver = new FirefoxDriver();
 }

  @Test
 public void Test01() throws Exception {
  URL url = PageFactory.initElements(driver,
    URL.class);
  url.geturl();
  
 }

  @Test
 public void Test02() throws Exception {
  Task = PageFactory.initElements(driver,
    ASSERT.class);
  Task.search();  
  
  }

  @Test
 public void Test03() throws Exception {  
  Task = PageFactory.initElements(driver,
    ASSERT.class);  
  Task.assertsearch();

  }
  
  @AfterTest
 public void tearDown() throws Exception {
  driver.quit();
 }

}



Open Google | URL.java


package packagename;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.WebDriverWait;

public class URL{
public WebDriver driver;
private String baseUrl;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();

public URL(WebDriver driver) {
this.driver = driver;
driver.get("http://www.google.co.in");
}

public ASSERT geturl() {  
System.out.println("URL opened successfully");
return PageFactory.initElements(driver, ASSERT.class);
}


}



Search & Assert | last.java


package packagename;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;

public class ASSERT {

public WebDriver driver;

public ASSERT(WebDriver driver) {
this.driver = driver;
  //driver.get("https://seleniumworkz.wordpress.com/wp-admin/edit.php");
}
 
public void search() throws Exception{
//  search google
driver.findElement(By.name("q")).sendKeys("Prashanth Sams");
driver.findElement(By.name("q")).submit();
Thread.sleep(4000);
}

public void assertsearch() throws Exception{
//  assert google search
Boolean b = driver.getTitle().contains("Prashanth Sams");
System.out.println(b);
}
}
