Test Automation Framework Using Selenium - Part I

[Prior Post in Series - Selenium Automation Best Practices]
[Next Post in Series Part II]


In our continious effort to develop automation framework please find high level approach to building automation framework. This is based on chapter. I have also noted coding guidelines in writing this code.
  • Coding Standards
  • High Level Approach 
Approach is independant test suites for individual pages in a site. Already in earlier posts I have created test pages. I am reusing the pages and verifier code. This is a draft outline of the framework.

TestRun.Java - In this file we instantiate selenium instance, open the page.
FirstPage.Java - This has methods for opening first page and verifying first page items
SecondPage.Java - Seperating methods and verifiers for that particular page to keep test suite maintainable. Verifier for second page is provided in this file

Improvements (Next Upcoming Posts)
  • Logging
  • Reporting
  • Continous Integration Server
  • Implementing Data Driven Testing by reading data from XML file
In next posts I plan to learn and Implement improvements.
1. Create a project and add required libraries. Verify earlier post
2. TestRun.Java
import com.thoughtworks.selenium.Selenium;
import static org.testng.Assert.assertTrue;
import org.testng.annotations.*;
import com.thoughtworks.selenium.*;
public class TestRun
{
Selenium selenium;

@BeforeTest
public void setUp()
{
      selenium = new DefaultSelenium("localhost",4444,"*iehta","http://sqlandsiva.blogspot.com/");
      selenium.start();
}

@AfterTest
public void tearDown()
{
      selenium.stop();
}

@Test
public void firstPageTestCase()
{
      FirstPage fp = new FirstPage(selenium);
      fp.clickFirstPage();
      fp.verifyListItems();
      SecondPage sp = fp.openSecondPage();
      sp.verifyUnorderedListItems();
}
}
3. FirstPage.Java
import com.thoughtworks.selenium.Selenium;
import static org.testng.Assert.assertTrue;
import java.util.Vector;
import org.testng.Assert;
import org.testng.annotations.*;
import com.thoughtworks.selenium.*;
public class FirstPage{
Selenium selenium;
public static String FIRST_PAGE_LINK = "/2011/01/test-xml-page-for-selenium.html";
public static String SECOND_PAGE_LINK = "/2011/01/test-page-for-selenium-example.html";

public FirstPage(Selenium selenium)
{
      this.selenium = selenium;
     
}
public FirstPage clickFirstPage()
{
      System.out.println("Opening First Page");
      clickFirstPage(FIRST_PAGE_LINK);
      selenium.waitForPageToLoad("30000");
      return new FirstPage(selenium);
}

public SecondPage openSecondPage()
{
      System.out.println("Opening Second Page");
      clickSecondPage(SECOND_PAGE_LINK);
      selenium.waitForPageToLoad("30000");
      return new SecondPage(selenium);
}

private void clickSecondPage(String number)
{
      selenium.open(SECOND_PAGE_LINK);
}

private void clickFirstPage(String number)
{
      selenium.open(FIRST_PAGE_LINK);
}

public void verifyListItems()
{
      System.out.println("In FirstPage Test Method");
      try
      {
            System.out.println("Running FirstPage Test");
            int i=1,j=1;
            while(selenium.isElementPresent("//table[@id='firstTable']//tr["+i+"]/td["+j+"]"))
            {
            while(selenium.isElementPresent("//table[@id='firstTable']//tr["+i+"]/td["+j+"]"))
            {
                  System.out.println("Value is " + selenium.getText("//table[@id='firstTable']//tr["+i+"]/td["+j+"]"));
                  j++;
            }
            j=1;
            i++;
      }
      }
      catch(Exception ex)
      {
                        ex.toString();
      }
}
}
4. SecondPage.java
import com.thoughtworks.selenium.Selenium;
import static org.testng.Assert.assertTrue;
import java.util.Vector;
import org.testng.Assert;
import org.testng.annotations.*;
import com.thoughtworks.selenium.*;
public class SecondPage{
Selenium selenium;

public SecondPage(Selenium selenium)
{
      this.selenium = selenium;
}

public SecondPage clickFirstPage()
{
      return new SecondPage(selenium);
}

public void verifyUnorderedListItems()
{
      System.out.println("In SecondPage Test Method");
      try
      {
            int j=1;
            while(selenium.isElementPresent("//div[@id='OrderList']/ol/li["+j+"]"))
            {
                  System.out.println("Value is " + selenium.getText("//div[@id='OrderList']/ol/li["+j+"]"));
                  j++;
            }
            j=1;
           
            while(selenium.isElementPresent("//div[@id='UnOrderedList']/ul/li["+j+"]"))
            {
                  System.out.println("Value is " + selenium.getText("//div[@id='UnOrderedList']/ul/li["+j+"]"));
                  j++;
            }
            j=1;
            while(selenium.isElementPresent("//div[@id='Links']/a["+j+"]"))
            {
                  System.out.println("Value is " + selenium.getText("//div[@id='Links']/a["+j+"]"));
                  j++;
            }
           
      }
      catch(Exception ex)
      {
                        ex.toString();
      }
}
}


Start Selenium Server. Run TestRun.java as TestNG test.  This is a working example. Please find output

Siva sir,

Good article and sampletest programs. Very useful to understand the test program development using Selenium-RC (Java API) and TestNG.

Thank you, Krishna
