Capturing all Links in a page, filtering and visiting filtered pages.

Purpose: Capturing all Links in a page, filtering and visiting filtered pages.


In general while testing any application we are facing a situation where we need to visit specific link available on the Web Page. The Following script help floks how to handle it.

In the following example, I am going to visit 'www.google.com', captures all the links available on the page, filter the required link and visit that link page.

import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Links {
 public static void main(String[] args) throws InterruptedException {

  WebDriver driver = new FirefoxDriver();
  driver.get("http://www.tata.com/");
  driver.manage().window().maximize();
//  Extract all links from the webpage using selenium webdriver
  List<WebElement> all_links_webpage = driver.findElements(By.tagName("a"));

//  Print total no of links on the webpage
  System.out.println("Print total no of links on the webpage---------------------------------------------");
  System.out.println(all_links_webpage.size());

//  Filter the Link and visit that link
  System.out.println("Print Links------------------------------------------------------------------------");
  for(int i=0;i<all_links_webpage.size();i++)
  {
   Thread.sleep(1000);
   if(all_links_webpage.get(i).getText().toLowerCase().contains("contact"))
   {
    System.out.println("Search Resutl found");
   String link = all_links_webpage.get(i).getAttribute("href");
   driver.navigate().to(link);
   Thread.sleep(3000);
   break;
   }
  }
 driver.quit();
 }
}

How to Run Webdriver Script under Internet Explorer and Google Chrome

Purpose: How to Run Webdriver Script for Internet Explorer and Google Chrome

Running Webdriver script for Internet Explorer & Chrome is not as same as working with Firefox browser. Following are the steps to Run:

Step 1: In order to run, we need to download IE Driver & Chrome Driver and we can download from https://code.google.com/p/selenium/downloads/detail?name=IEDriverServer_Win32_2.31.0.zip
https://code.google.com/p/chromedriver/downloads/list

Step 2: Include the respective drivers in to the Path

Step 3: Set the System property using the following Command which takes two parameters Driver and location of the driver.

System.setProperty("webdriver.ie.driver", "Drivers\\IEDriverServer.exe");

Step 4: Now create an Driver Object for IE using the following command

driver = new InternetExplorerDriver();

Once we start running the script Internet Explorer will open and execute script.

Following is the sample code for IE and kept commented code for Google Chrome

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
public class DriversExample{
private static InternetExplorerDriver driver;
//private static ChromeDriver driver;
@BeforeClass
 public void beforeClass()
 {
  System.setProperty("webdriver.ie.driver", "Drivers\\IEDriverServer.exe");
  driver = new InternetExplorerDriver();
//  System.setProperty("webdriver.chrome.driver", "Drivers\\chromedriver.exe");
//  driver = new ChromeDriver();
  }
@Test
 public void testDrivers() throws Exception
 {
  driver.get("http://www.google.com");
  Thread.sleep(3000);
 }
@AfterClass
 public void afterClass()
 {
  driver.close();
 }
}

Capturing all Links on a Web Page and visiting those links using Web Driver

Purpose: Capturing all Links on a Web Page and visiting those links

In general while testing any application we are facing a situation where we need to visit each link available on the Web Page. The Following script help floks how to handle it.

In the following example, I am going to visit 'www.google.com', captures all the links available on the page, visiting each link and coming back to home page.

importjava.util.List;

importorg.openqa.selenium.By;

importorg.openqa.selenium.WebDriver;

importorg.openqa.selenium.WebElement;

importorg.openqa.selenium.firefox.FirefoxDriver;

public class Links {

private static String homeWindow = null;

private static String[] links = null;

private static int linksCount = 0;

public static void main(String[] args) throws InterruptedException {

WebDriver driver = new FirefoxDriver();

driver.get("http://www.google.com/");

// Fllowing instruction extract all links from the webpage using selenium webdriver

List<WebElement> all_links_webpage = driver.findElements(By.tagName("a"));

// Print total no of links on the webpage

System.out.println("Print total no of links on the webpage----------------------------------------------------");

linksCount = all_links_webpage.size();
System.out.println(linksCount);

links= new String[linksCount];// Following instruction stores each link and Prints on console

System.out.println("Print Links-----------------------------------------------------------------------------------");

for(int i=0;i<linksCount;i++)

{

links[i] = all_links_webpage.get(i).getAttribute("href");

System.out.println(all_links_webpage.get(i).getAttribute("href"));

}

// Following instruction Return an opaque handle to this window that uniquely identifies it within this driver instance.

// This can be used to switch to this window at a later date

homeWindow = driver.getWindowHandle().toString();

// Visiting Each Link in on the Page

System.

out.println("Visiting Each Links------------------------------------------------------------------------");

for(int i=0;i<linksCount;i++)

{

driver.navigate().to(

links[i]);

Thread.sleep(3000);

driver.switchTo().window(

homeWindow);

}

driver.quit();

}

}

Maximizing Browser Window using Selenium Rc and Web Driver

Purpose: Maximizing Browser window using Selenium RC and Web Driver

When ever we are opening Web Browser using Selenium RC and Web Driver, it will open in Resized state. But that will not give complete view of the Browser conten. In order to maximize the the window we need to use two different methods in RC and Web Driver.

Maximizing the Browser Window using RC

Once you started the Browser use the following Selenium RC command to maximize the Browser Window
(browser is the object of my DefaultSelenium Class)

browser.windowMaximize();

Maximizing the Browser Window using Web Driver:

It is not as same as RC in Web Driver. We need to use the following command

( driver is the Object of Respective Browser Driver Class )

driver.manage().window().maximize();
 

Unsupported Major/Minor Version issue while executing Selenium Scripts / Java Programs using Eclipse IDE

Purpose: When ever we are executing Selenium Scripts / Java Program which is developed / written in some othere version than our version we will get the error "Java.lang.UnsupportedClassVersionError: .............................Unsupported major.minor version"

If you are executing the program using Console / Command Prompt, using additional parameter -source <version number>

For example, if your file name is VersionError.java and executing through Command Prompt use the following command to execute successfully:

javac -source 1.4 VersionError.java

The program will compile successfully.

If you are executing the code using Eclipse IDE follow the steps mentioned below:

Step 1: Click on 'Project' menu option and select 'Properties' submenu.

Step 2: Click on Project Facts from RNP and Select Java in RNP

Step 3: Select required version of Java and click on OK.

Now Run the application and the issue will be resolved.

Switching between Windows using Selenium Webdriver

Purpose: Switching between Windows using Selenium Webdriver

We come across to handle switching b/w windows while accessing different webpages. Inroder to automate switching b/w windows, following steps will help you to write Selenium Webdriver Script with the help of Java

It is not as easy as handling with Selenium Rc. We can achive with the help of getWindowHandle() and switchTo().window() methods.

Following is the Selenium Webdriver with Java script to handle popup windows:


package com.webdriver;
import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;
public class SwitchWindow {

 public static void main(String[] args) throws Exception
 {
  FirefoxDriver driver = new FirefoxDriver();
  driver.get("http://www.quackit.com/html/codes/");
  // Return an opaque handle to this window that uniquely identifies it within this driver instance. This can be used to switch to this window at a later date
  String parentWindow = driver.getWindowHandle().toString();
  driver.findElement(By.linkText("Pop up windows")).click();
  Thread.sleep(3000);
  assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Example HTML Popup Window Code:[\\s\\S]*$"));
    driver.findElement(By.linkText("Open a popup window")).click();
    // to switch control to the new popup window by name
    driver.switchTo().window("popUpWindow");
    assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Copy/Paste HTML Codes[\\s\\S]*$"));
    // closing the popup window
  driver.close();
  // to switch control from popup window to another window, here parent window
  driver.switchTo().window(parentWindow);
  assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Example HTML Popup Window Code:[\\s\\S]*$"));
  driver.close();
 }
}

// Code for TestNG

package com.webdriver;
import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;
public class SwitchWindow {
 FirefoxDriver driver;
  @Test
  public void testSwitchWindow() {
   driver.get("http://www.quackit.com/html/codes/");
   // Return an opaque handle to this window that uniquely identifies it within this driver instance. This can be used to switch to this window at a later date
   String parentWindow = driver.getWindowHandle();
   assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*HTML Codes - Free[\\s\\S]*$"));
   assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Pop up windows[\\s\\S]*$"));
   driver.findElement(By.linkText("Pop up windows")).click();
   assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Open a popup window[\\s\\S]*$"));
   driver.findElement(By.linkText("Open a popup window")).click();
   // to switch control to the new popup window by name
   driver.switchTo().window("popUpWindow");
   assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Copy/Paste HTML Codes[\\s\\S]*$"));
   // closing the popup window
   driver.close();
   // to switch control from popup window to another window, here parent window
   driver.switchTo().window(parentWindow);
   assert(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Open a popup window[\\s\\S]*$"));
  }
  @BeforeClass
  public void beforeClass() {
   driver = new FirefoxDriver();
   driver.manage().window().maximize();
  }
  @AfterClass
  public void afterClass() {
   driver.close();
  }
}
