5.2 Object Repository

We use object repository to store all our page controls in a common class, this way whenever there are changes in the UI, the respective changes can be updated in the Object Repository, without having to go to the actual code. A person with lesser knowledge of java platform can also easily do this.

Below is the script without object Repository. We will prepare an OR (Object Repository) for the same script.

package com.selenium;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class WithoutOR {

    private WebDriver driver;
    private String baseUrl;

    @BeforeTest
    public void initialization() {
        driver = new FirefoxDriver();
        baseUrl = "http://docs.seleniumhq.org/";
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.manage().window().maximize();
    }

    @Test
    public void testMethod() throws InterruptedException {
        driver.get(baseUrl + "/");
        driver.findElement(By.linkText("Projects")).click();
        driver.findElement(By.linkText("nsaikiran")).click();
        Assert.assertTrue(isElementPresent(By.name("submit")));
    }

    @AfterTest
    public void cleanup() {
        driver.quit();
    }

    private boolean isElementPresent(By by) {
        try {
            driver.findElement(by);
            return true;
        } catch (NoSuchElementException e) {
            return false;
        }
    }
}

Create A class named ObjectRepo as below.

package com.selenium;

public interface ObjectRepo {
    public String linkProejct = "Projects";
    public String linkDownload = "nsaikiran";
    public String donateBtn = "submit";

}

Update the script as below. The script is now totally free of any hardcoding. Whatever changes happen in the UI can be udpated in the object Repository.

package com.selenium;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class WithoutOR implements ObjectRepo{

    private WebDriver driver;
    private String baseUrl;

    @BeforeTest
    public void initialization() {
        driver = new FirefoxDriver();
        baseUrl = "http://docs.seleniumhq.org/";
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.manage().window().maximize();
    }

    @Test
    public void testMethod() throws InterruptedException {
        driver.get(baseUrl + "/");
        // All the elements are fetched from Object Repository
        driver.findElement(By.linkText(linkProejct)).click();
        driver.findElement(By.linkText(linkDownload)).click();
        Assert.assertTrue(isElementPresent(By.name(donateBtn)));
    }

    @AfterTest
    public void cleanup() {
        driver.quit();
    }

    private boolean isElementPresent(By by) {
        try {
            driver.findElement(by);
            return true;
        } catch (NoSuchElementException e) {
            return false;
        }
    }
}
