Hi everyone welcomes back once again to Selenium webdriver tutorial. Today we are going to cover the very basic check that is a must in every application check. We will find broken links using selenium and how we can check what is the status of the same.

What is find broken links using selenium

By the name itself, we can identify that we need to find broken links using selenium it means we need to check the link which is pointing to wrong URL or invalid URL.

I am sure you must have faced 404 page not found an issue in most of the application which is called broken link.

It does not only link you may also have to verify the images as well that we will see in the next tutorial.

While doing validation you only have to verify status

1- 200- Success- ok

Scenario for find broken links using selenium

Before jumping to the code let’s take one simple example to get the actual concept.

Example1- Suppose we have one application which contains 400 links and we need to verify the link is broken or not.

Approach 1-

Manual Process- Go to each link and verify the link is working or not.

Do you think it is the valid approach? No, it will take a full day to verify and you will not get the same efficiency and interest as well.

Approach 2-

Smart work- Write a code which will check all the link and will verify the status as well.

Since we all are smart so we will take Smart work and will see how to find broken links using selenium.

Before I start let me introduce HttpURLConnection class which will help us to verify the status of the response.

Precondition-

1- Selenium setup should be completed

Program for find broken links using selenium

import java.net.HttpURLConnection;
import java.net.URL;
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 VerifyLinks {
	public static void main(String[] args) 
	{
		WebDriver driver=new FirefoxDriver();
		
		driver.manage().window().maximize();
		
		driver.get("http://www.google.co.in/");
		
		List<WebElement> links=driver.findElements(By.tagName("a"));
		
		System.out.println("Total links are "+links.size());
		
		for(int i=0;i<links.size();i++)
		{
			
			WebElement ele= links.get(i);
			
			String url=ele.getAttribute("href");
			
			verifyLinkActive(url);
			
		}
		
	}
	
	public static void verifyLinkActive(String linkUrl)
	{
 try 
 {
 URL url = new URL(linkUrl);
 
 HttpURLConnection httpURLConnect=(HttpURLConnection)url.openConnection();
 
 httpURLConnect.setConnectTimeout(3000);
 
 httpURLConnect.connect();
 
 if(httpURLConnect.getResponseCode()==200)
 {
 System.out.println(linkUrl+" - "+httpURLConnect.getResponseMessage());
 }
 if(httpURLConnect.getResponseCode()==HttpURLConnection.HTTP_NOT_FOUND) 
 {
 System.out.println(linkUrl+" - "+httpURLConnect.getResponseMessage() + " - "+ HttpURLConnection.HTTP_NOT_FOUND);
 }
 } catch (Exception e) {
 
 }
 } 
	
	
	 
}

Output

You can see we are getting 49 links and all seems OK.

Congrats 🙂

    Hi Mukesh,
    How to verify the other page links give errors 404 in the website. because this method only verify the few links but others are not found.

    • Mukesh Otwani says

      Hi Rajnish,

      Using Selenium and href attribute, you can only fetch current webpage links. If you want to check links available on other page then you have to navigate to intended page.

  11. Girija says

    Hello Mukesh,
    This method is working when broken image gives 404 error page. But what should we do when a website have managed 404 page to standardised error page ?

    Hi Mukesh,

    Can you please make detail video of Web Services testing(Soupui and other related concepts) ? this will be very helpful.
    Thanks in advance.

    • Mukesh Otwani says

      Hi Tauseef,

      To achieve your objective, you have use looping mechanism so that in every iteration, Serial Number comes. For Page Name depends on your naming convention, Page Link get be acquired using driver.getCurrentUrl() and Status you can return as per execution flow end.

    Hi Mukesh, I am facing issue with appium installation I have downloaded all the tools and jar files and installed but padnet, genymotion, appiumserver are not working in my system and selenium web driver is going fine
    Can you please help about this issues if you have done vedeos for this please share.

    I am following your vedeos and past from 3montgs it’s good and helped soo much…thanks

  17. Daniel says

    Why is the method verifyLinkActive public? I give methods the smallest scope needed, which would in this case be private. Is it necessary that other classes can use this method too?

  18. Anshul Rajvanshi says

    Hi Mukesh,
    Few questions.
    1) Opening google via Headless is working fine. But not able to open Secure sites – Any solution to it please?
    2) We are suing Selenium 3.X and ROBOT framework. Got to know htmlunit driver is not a part of the package.
    Do we have to add the PATH of htmlunit driver (downloaded separately) to PATH environments variable?

  20. Partho Dutta says

    Hi Mukesh
    In my application first i have to login then i have to find the broken link for entire application. Could he please suggest me how to do this?

    • Mukesh Otwani says

      Hi Partho,

      I can’t see any difficulties in your mentioned scenario. Login window is usual and very generic activity. And once you login, then you can find all broken links. If this is not what you meant then kindly elaborate your requirement.

  21. Sri Datta says

    Hi Mukesh,

    Im getting java.net.UnknownHostException this exception while running the code. Is it because of proxy issue? Please help.

    Thanks

    Hi Mukesh,
    The videos and the blog you have are great. I’m new in automation and I’m learning a lot from you. Very informative and very easy to understand. This code is working great, too. I just have a question maybe you can help me with that.
    Is there a way to test links only in the content of website? Can we exclude the header and footer links? Do you think it is possible?
    Thank you again!

  24. Saurabh says

    Hello Mukesh,

    Good Job Mukesh,
    Mukesh I am getting ‘IndexOutOfBondException’ using this code if my web page having more than 300 links. Can you please suggest me what I can do in this case ?

    • Mukesh Otwani says

      Hi Saurabh,

      This is java exception which when you refer an index in array which is not available. Or else you can take any List implementation like ArrayList or LinkedList whose length is dynamic in nature. Hope this should solve your problem.
