When you encounter 404/Page Not Found/Dead Hyperlinks on a website, what do you think of it? You would find it irritating to encounter broken links, so you should continuously concentrate on eliminating their presence in your web product (or website).



The rankings of your web product on search engines (like Google) will also suffer if it contains numerous pages (or links) that lead to a 404 error (or page not found). Dead links could damage the credibility of your product as the user needed to get the information for which they have visited the page.&nbsp;



In this blog, we will look into finding and locating broken links using Selenium WebDriver;

<h2 class="wp-block-heading" id="h-what-are-broken-links">What are Broken links?</h2>



A broken link on a website leads to a page or resource that is no longer available. This can happen for various reasons, such as the page being deleted, moved to a different URL, or the website being temporarily down. Broken links can occur on any website and can be found on pages, images, videos, and other resources.



Broken links can be a problem for website visitors and search engines, leading to a poor user experience and negatively impacting search engine optimization (SEO). It’s also why building <a href="https://bluetree.digital/high-authority-backlinks/" target="_blank" rel="noreferrer noopener">high-authority backlinks</a> matters those references carry more weight, so you don’t want them pointing to dead pages. When a user clicks on a broken link, they will typically be taken to a &#8220;404 not found&#8221; page, which can be frustrating and cause them to leave the website. Additionally, search engines may view broken links as a sign of a poorly maintained website, which can lead to a lower search engine ranking.



To avoid these issues, it&#8217;s essential to regularly check your website for broken links and fix them as soon as they are discovered. This can be done manually by visiting each page of your website and clicking on each link to see if it leads to a &#8220;404 not found&#8221; page or by using automated tools such as <a href="https://www.selenium.dev/" target="_blank" rel="noreferrer noopener nofollow">Selenium</a> or other link checker software.



<h2 class="wp-block-heading" id="common-reasons-for-broken-links">Common Reasons for Broken Links.</h2>



There are several reasons why broken links may appear on a website, including.&nbsp;



<ul class="wp-block-list">
<li>Page Deletion: A previously linked page may have been deleted, causing the link to lead to a &#8220;404 not found&#8221; page.</li>



<li>URL Changes: If a page&#8217;s URL is changed, any links pointing to the old URL will become broken.</li>



<li>Website Redesign: During a website redesign, URLs may change, causing previously valid links to become broken.</li>



<li>Moving to a New Domain: If a website is moved to a new domain, all links pointing to the old domain will become broken.</li>



<li>Typos: Mistyping a URL or copying and pasting it wrongly can result in a broken link.</li>



<li>Third-Party Content: If a website links to content hosted on another website, and that content is removed or moved, the link will become broken.</li>



<li>Server Outages: If a website is temporarily down, links to that site will become broken.</li>
</ul>



By regularly checking for and fixing broken links, website owners can ensure that their website provides a good user experience and positively impacts their SEO.



<h2 class="wp-block-heading" id="reasons-to-check-for-broken-links">Reasons to Check for Broken Links</h2>



There are several reasons why it&#8217;s important to check for and fix broken links on a website:



<ul class="wp-block-list">
<li>User Experience: Broken links can frustrate website visitors and lead to a poor user experience. If a user clicks on a broken link, they will be taken to a &#8220;404 not found&#8221; page, which can be confusing and cause them to leave the website.</li>



<li>Search Engine Optimization (SEO): Search engines view broken links as a sign of a poorly maintained website, which can negatively impact the website&#8217;s search engine ranking.</li>



<li>Maintenance: Broken links can signal that a website needs to be regularly maintained and updated, leading to other issues, such as outdated content and security vulnerabilities.</li>



<li>Data Accuracy: Broken links can lead to incorrect or outdated information being displayed on a website, which can harm the website&#8217;s reputation.</li>



<li>Link Equity: When a website links to another page, it passes on some of its link equity, a measure of the value that search engines place on a link. If the linked page is no longer available, the link equity is lost, which can negatively impact the linking website&#8217;s search engine ranking. Make sure to improve your metrics with the correct use of the <a href="https://buzznberry.com/link-building-services/" target="_blank" rel="noreferrer noopener nofollow">white hat link building</a> so your website can have better rankings.</li>

</ul>



<h2 class="wp-block-heading" id="different-http-status-codes">Different HTTP Status Codes</h2>



HTTP (Hypertext Transfer Protocol) status codes are numerical codes that are returned by a web server to indicate the status of a request made by a client (e.g., a web browser). The most encountered HTTP status codes are



<ul class="wp-block-list">
<li>200 OK: The request was successful, and the server has returned the requested content.</li>



<li>201 Created: The request was successful, and the server has created a new resource.</li>



<li>204 No Content: The request was successful, but there needs to be a representation to return (i.e., the response is empty).</li>



<li>300 Multiple Choices: The request has multiple options, and the server directs the client to choose one.</li>



<li>301 Moved Permanently: The requested resource has been moved to a new URL, and future requests should use the new URL.</li>



<li>302 Found (Previously &#8220;Moved temporarily&#8221;): The requested resource has been temporarily moved to a new URL.</li>



<li>304 Not Modified: The client&#8217;s cached copy of the resource is up to date, and the server indicates that the client should use its cached copy.</li>



<li>400 Bad Request: The request must be understood or include the required parameters.</li>



<li>401 Unauthorized: Authentication failed, or the user does not have permission for the requested operation.</li>



<li><a href="https://www.cloudways.com/blog/wordpress-403-forbidden-error/" target="_blank" rel="noreferrer noopener">403 Forbidden</a>: Authentication succeeded, but the authenticated user cannot access the requested resource.</li>



<li>404 Not Found: The requested resource could not be found on the server.</li>



<li>500 Internal Server Error: An error occurred on the server while processing the request.</li>
</ul>



<h2 class="wp-block-heading" id="how-to-find-broken-links-in-the-selenium-webdriver">How to Find Broken Links in the Selenium WebDriver?</h2>



To find broken links in Selenium WebDriver, you can use the following steps:



<h3 class="wp-block-heading" id="1-retrieve-all-links-from-a-web-page">1. Retrieve all links from a web page: </h3>



You can use Selenium WebDriver&#8217;s &#8220;findElements&#8221; method to find all the links (i.e., &#8220;a&#8221; elements) on a web page. You can store the links in a list for later processing.



<h3 class="wp-block-heading" id="2-verify-each-link">2. Verify each link: </h3>



For each link, you can use the &#8220;getAttribute&#8221; method to retrieve the &#8220;href&#8221; attribute of the link, which represents the URL that the link points to. You can then use the &#8220;HttpURLConnection&#8221; class in Java to check the status code of the URL.



<h3 class="wp-block-heading" id="3-check-the-status-code">3. Check the status code: </h3>



You can use the &#8220;getResponseCode&#8221; method of the &#8220;HttpURLConnection&#8221; class to retrieve the HTTP status code of the URL. The link is broken if the status code is not in the 200 or 300 range. You can store the broken links in a separate list for later reporting.



<h3 class="wp-block-heading" id="4-repeat-for-each-link">4. Repeat for each link: </h3>



Repeat the above steps on the page until all links have been checked.



<h3 class="wp-block-heading" id="5-report-the-results">5. Report the Results: </h3>



After all, links have been checked, you can use Selenium WebDriver&#8217;s &#8220;assert&#8221; method to check that the list of broken links is empty. If the list is not empty, you can report the broken links to the console or write them to a file for later analysis.



Let&#8217;s understand the code.&nbsp;



Code Snippet:



package demo;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Iterator;
import java.util.List;

import org.openqa.selenium.By;

public class Demo {

	

	public static void main(String[] args) {
// TODO Auto-generated method stub

	 System.setProperty(&#8220;webdriver.chrome.driver&#8221;,&#8221;.\chromedriver.exe&#8221;);
	 	 
	 //Initialising the driver
	 WebDriver driver = new ChromeDriver();

		String homePage = &#8220;https://google.com/&#8221;;
		String url = &#8220;&#8221;;
		HttpURLConnection con = null;
		int responseCode = 200;

		driver = new ChromeDriver();

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

		driver.get(homePage);

		List links = driver.findElements(By.tagName(&#8220;a&#8221;));

		Iterator it = links.iterator();

		while (it.hasNext()) {

			url = it.next().getAttribute(&#8220;href&#8221;);


			try {
				con = (HttpURLConnection) (new URL(url).openConnection());

				con.setRequestMethod(&#8220;HEAD&#8221;);

				con.connect();

				responseCode = con.getResponseCode();

				if (responseCode &gt;= 400) {
					System.out.println(url + &#8221; is a broken link&#8221;);
				} else {
					System.out.println(url + &#8221; is a valid link&#8221;);
				}

			} catch (MalformedURLException e) {

				e.printStackTrace();
			} catch (IOException e) {

				e.printStackTrace();
			}
		}

		driver.quit();

	}
}



Output:



The output indicates all valid links except one broken link.

An Easy Way to Build and Execute Selenium Projects

It&#8217;s already 2023, and as we all know, software testing has advanced significantly. But it doesn&#8217;t imply we should ignore the fundamentals or the basics. The &#8220;7 Principles of Software Testing&#8221; are such basics that we should always adhere to. You may have studied these concepts as part of your ISTQB certification training when you started your testing career.



Did you just forget about them after reading the book, as you did with previous theoretical papers? Or do you continue to adhere to or follow these principles in your day-to-day testing activities? We should follow particular processes for testing activities, which may appear more difficult at first, but will save us a lot of time in the long run.



As a quality assurance measure, testing is essential to the software development process. By testing the software, developers can ensure that the product meets the requirements and is free of defects.



There are various types of testing that can be employed, depending on the stage of development. For example, unit testing is conducted on individual components or modules, while integration testing focuses on the interactions between different modules/components. System testing is a comprehensive testing approach that covers the entire system, from end to end.&nbsp;



So, let us go through the principles of Software testing that every software tester should be aware of in-depth, these will be helpful in all stages of testing.

<h2 class="wp-block-heading" id="what-are-the-7-principles-of-software-testing">What are the 7 Principles of Software Testing?</h2>



Below are the 7 fundamental principles :



<ol class="wp-block-list"><li>Testing shows the presence of defects</li><li>Exhaustive testing is impossible</li><li>Early testing</li><li>Defect clustering</li><li>Pesticide paradox</li><li>Testing is context dependent</li><li>Absence-of-errors fallacy</li></ol>



<h3 class="wp-block-heading" id="1-testing-shows-the-presence-of-defects-not-their-absence">1. Testing shows the presence of defects (not their absence)</h3>



Who doesn&#8217;t love identifying defects? We&#8217;d all like to. Every product or web application I use will have defects 😀. Primarily, we conduct testing to identify flaws and deviations. We concentrate on the faults and vulnerable modules.



Also, we perform different types of testing to uncover the defects. Once the software has been developed and tested, it is ready for release. However, in some cases, defects may still be present. In these cases, it is important to have a process in place for tracking and resolving defects.



Because there are still a few defects in the system that you were unable to discover for a variety of reasons. That doesn&#8217;t imply we&#8217;re not competent. This issue can be mitigated by updating or revising the scenarios and test data. As a result, we can endeavor to develop day by day.



<h3 class="wp-block-heading" id="2-exhaustive-testing-is-impossible">2. Exhaustive testing is impossible</h3>



Exhaustive testing is impossible. You cannot utilize every permutation and combination feasible. That&#8217;s why we have to rely on the heuristics and best practices to guide our testing efforts. We use our business and domain knowledge to <a href="https://testsigma.com/blog/test-efficiency/" target="_blank" rel="noreferrer noopener">test efficiently</a>.&nbsp;



There are several reasons why exhaustive testing isn&#8217;t really possible. The first point is that testing anything and everything is impossible. Second, testing everything in a reasonable timeframe is impossible. Third, it is difficult to foresee every single problem. Fourth, it is hard to predict how the test will be performed. Finally, exhaustive testing is impossible to validate.



There is no such thing as a perfect test in software testing. There will always be some edge cases that we get to neglect or sections of the code that are more complex than others. That is why it is critical to employ a range of testing approaches and to always seek new ways to improve our testing process.



No matter how much time and effort we put into it, some bugs will always creep through the gaps. We can only do our best to reduce the number of potential issues and ensure that we have a comprehensive testing methodology to capture as many of them as possible.



<h3 class="wp-block-heading" id="3-early-testing">3. Early testing</h3>



Testing is a critical component of software development. Early testing, on the other hand, is critical since it helps developers to detect and correct problems before they become mainstream. Also, this saves a lot of money and effort.&nbsp;



Conducting user testing is one of the greatest methods to uncover problems early on. When a user tests software, they undertake tasks that are essential to them. This enables developers to learn how users interact with the product and assess if the features and design are functioning properly.



User testing may also assist developers to assess whether a proposed feature is feasible. They can evaluate if consumers will find the new feature beneficial and whether it will create any problems by testing it with a group of users.



Early testing is critical for a number of reasons. For instance, it can detect possible problems early on, before they trigger significant problems. Early testing can also assist to enhance the overall quality of the completed product. Finally, early testing can assist to enhance development efficiency by letting developers focus on correcting issues that are discovered early on.



<h3 class="wp-block-heading" id="4-defect-clustering">4. Defect Clustering</h3>



Defect clustering refers to the tendency for faults to concentrate in particular areas of code. This might be due to a variety of variables, such as how the code is designed, how the team is organized, or just how the human brain works.



For whatever reason, defect clustering can have a significant impact on your development process. If the majority of your defects are concentrated in one region of code, you&#8217;ll spend most of your time and effort repairing them there.



It is a problem-solving technique that helps identify and resolve defects in products. It is based on the observation that defects are often grouped together in clusters.



As anyone in software development knows, defects are inevitable. But what many people don&#8217;t realize is that defects tend to cluster together. Here&#8217;s what you need to know about defect clustering and how to deal with it effectively.



Have you heard about <a href="https://en.wikipedia.org/wiki/Pareto_principle" target="_blank" rel="noreferrer noopener">Pareto Principle</a>?&nbsp;



The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the &#8220;vital few&#8221;). Other names for this principle are the 80/20 rule, the law of the vital few, or the principle of factor sparsity.



Knowing this might be very useful for your testing; if we identify one problem in a certain module/area, there is a good probability we will find many more. Identifying the most complicated components, or regions with the greatest dependencies or change, for example, might help you focus your testing on the most critical risk areas. This should always be the primary consideration when planning future test activities.



<h3 class="wp-block-heading" id="5-pesticide-paradox">5. Pesticide Paradox</h3>



The pesticide paradox describes how, while pesticides are intended to kill pests, they frequently have the opposite effect. That is, they have the potential to boost insect populations. This paradox arises because pesticide usage might result in the evolution of insect resistance. When this occurs, insecticides no longer efficiently kill the bugs, allowing the pests to thrive.



Similarly, the same testing technique and test scenarios may not help in the discovery of new defects. As software testers, we must always strive to improve test quality in order to offer a high-quality product. We must also regularly evaluate and examine the Test process, Test cases, Approach, and Test data in order to overcome the Pesticide Paradox. Retrospective meetings can be of greater assistance here.



<h3 class="wp-block-heading" id="6-testing-is-context-dependent">6. Testing is context-dependent</h3>



There is no questioning the significance of testing. But understanding when and how to test is much more crucial. There is no right or wrong answer since testing is context-dependent. The idea is to use your best judgment to determine what is appropriate for your individual scenario.



Here are a few things to consider during testing:



1. Do not conduct tests in a vacuum



Make certain that you understand the context in which your code will be utilized. This will assist you in determining what needs to be tested and how to test it.



2. Keep things simple



Try not to test everything all at once. Begin with the fundamentals and progressively add more exams as needed.



3. Be meticulous



Once you&#8217;ve determined what needs to be tested, make sure you test every part of it. Testing for both good and negative results is included.



<h3 class="wp-block-heading" id="7-absence-of-errors-fallacy">7. Absence-of-errors fallacy</h3>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" decoding="async" src="https://testsigma.com/blog/wp-content/uploads/Software-testing-process-07.jpg" alt="Zero defects identified ≠ Bug-Free Product
" class="wp-image-25259" width="600" height="400" /><figcaption>Zero defects identified ≠ Bug-Free Product </figcaption></figure></div>



Testing is performed to guarantee that the software/system is fit for purpose and satisfies the users&#8217; expectations. As a result, finding no defects does not indicate that the product meets the quality and expectations of the customers.



Assuming that something will never happen because it has never happened before. The absence-of-errors fallacy can give the illusion of security. Just because something has never happened before does not exclude it. It is a logical fallacy that occurs when it is assumed that something must be true since it has not been proven to be false. This is sometimes seen in arguments when one person argues, as if it were evidence, &#8220;There is no proof that X is true.&#8221;

This myth couldn&#8217;t be further from the truth. Testing principles are crucial in creating an effective Test Strategy and crafting robust test cases that catch errors. It&#8217;s like learning to drive for the first time.



When you start learning to drive, you pay attention to every detail: gear shifts, speed control, clutch handling, and more. But as you gain experience, driving becomes second nature. You effortlessly engage in conversations with passengers while seamlessly navigating the road.



Similarly, experienced testers have internalized testing principles to the point of applying them instinctively. They become integral to their testing approach, guiding their decisions without conscious effort. Therefore, the myth that testing principles are not used in practice is unfounded.



Understanding and embracing testing principles empowers testers to deliver high-quality software by leveraging industry best practices. So, let go of this myth and embrace the power of testing principles in your endeavors.
