Automating(Breaking) captcha using Selenium Webdriver

Usually most of the companies either use their own captchas or one of the third party captchas(Google, jQuery plugins) in the user registration page of their sites .So these pages can't be automated fully.Infact Captcha itself is implemented to prevent automation. As per official captcha site

A CAPTCHA is a program that  protects  websites against bots  by generating and grading tests that humans can pass but current computer programs cannot.

Captchas are not brakeable but there are some third party captchas that can be breakable and one of the example for it is "jQuery Real Person" captcha . Here is the documentation  :)

Here is the sample code to brake the "jQuery Real Person" Captcha using Selenium WebDriver.

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class captchaAutomtion { 
 
 WebDriver driver;
 
 @BeforeTest
 public void start(){
  driver = new FirefoxDriver();
 }
 
 @Test
 public void Test(){ 
  //Loading jQuery Real Person Captcha demonstration page
  driver.get("http://keith-wood.name/realPerson.html");
  JavascriptExecutor js = (JavascriptExecutor) driver;
  //Setting the captcha values
  js.executeScript("document.getElementsByName('defaultRealHash')[0].setAttribute('value', '-897204064')");
  driver.findElement(By.name("defaultReal")).sendKeys("QNXCUL");
  //Submit the form
  driver.findElement(By.xpath(".//*[@id='default']/form/p[2]/input")).submit(); 
 }

}

Do share some of the captcha plugins that can be breakable with me :P

5 different ways to refresh a webpage using Selenium Webdriver

Here are the 5 different ways, using which we can refresh a webpage.There might be even more :)

There is no special extra coding. I have just used the existing functions in different ways to get it work. Here they are :

1.Using sendKeys.Keys method

driver.get("https://accounts.google.com/SignUp");
driver.findElement(By.id("firstname-placeholder")).sendKeys(Keys.F5);

2.Using navigate.refresh()  method

driver.get("https://accounts.google.com/SignUp");  
driver.navigate().refresh();

3.Using navigate.to() method

driver.get("https://accounts.google.com/SignUp");  
driver.navigate().to(driver.getCurrentUrl());

4.Using get() method

driver.get("https://accounts.google.com/SignUp");  
driver.get(driver.getCurrentUrl());

5.Using sendKeys() method

driver.get("https://accounts.google.com/SignUp"); 
driver.findElement(By.id("firstname-placeholder")).sendKeys("\uE035");

See you in next post.

Null point exception while running webdriver script

Sometimes simple mistakes will take lot of time in debugging . I can bet on it :P
Today while runing a sample script I got errors like below :

at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

Here is the script with syntax error:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class AutoComplete {
 
 WebDriver driver;
 
 @BeforeTest
 public void start(){
 WebDriver driver = new FirefoxDriver();
 }
 
 @Test
 public void AutoComplete()
 {
 driver.get("http://mythoughts.co.in/");
 driver.manage().window().maximize();
 }

}

I just overlooked the above script and thought everything is fine. But the issue got fixed when I remove the "WebDriver" statement from the line 13 and script ran successfully.

Here is the script which ran successfully.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class AutoComplete {
 
 WebDriver driver;
 
 @BeforeTest
 public void start(){
 driver = new FirefoxDriver();
 }
 
 @Test
 public void AutoComplete()
 {
 driver.get("http://mythoughts.co.in/");
 driver.manage().window().maximize();
 }

}
