What are Broken Links?

Broken links on a web application refer to hyperlinks that no longer point to valid web pages or resources. When a user clicks on a broken link, they will receive an error message instead of being directed to the desired destination.

Why check for Broken Links using Selenium?

Checking for broken links on a web page using Selenium can help ensure a better user experience for website visitors. When users encounter broken links, they may become frustrated and leave the site. Additionally, search engines may penalize websites with broken links, as they can indicate a lack of attention to website maintenance and quality.

By using Selenium to automate the process of checking for broken links, website owners and developers can quickly identify and fix broken links before they become a problem for users or search engines. This can improve the overall quality and usability of the website, as well as potentially improve its search engine rankings.


How to identify missing/broken/invalid links using Selenium WebDriver: 

To identify broken links using Selenium WebDriver, you can follow these steps:

  1. Navigate to the web page using the WebDriver.

  2. Find all the links on the page using a selector, such as By.tagName("a").

  3. Iterate through each link and retrieve the value of the href attribute.

  4. Use a Java URL connection to make a request to the link's URL and retrieve the HTTP status code of the response.

  5. If the status code is in the range of 400-599, the link is likely broken and should be flagged for review.

Alternatively, you can use Selenium WebDriver with a third-party library such as Apache HttpClient or OkHttp to send HTTP requests and check for broken links. Some libraries may provide additional features such as automatic redirection handling or support for more advanced HTTP features.

Overall, using Selenium WebDriver to identify broken links on a web page is a valuable quality assurance step that can improve the user experience, prevent potential issues with search engine rankings and help maintain the quality of the website.

Selenium: File download handling.

Image
 When we download any file from internet, browser opens new pop-up windows and prompt user for action. Action could be open, save or save as.  Pop-up windows ( GUI ) could be different based on browser. When you are automating file download dialog box (or action), you should keep following points in mind. -           Browser -           Pop-up windows  title -           Pop-up GUI -           Available buttons on GUI -           File Type (Binary file, zip file, MS file etc..) -           Extra settings See how IE and FF pop-ups ... If you have any doubt or if it is not working , please provide me details and I will try to fix the problem. Func Down_FF_NonMS() Send("{TAB}{TAB}...

Major Differences between Python and Java

Image
Python and Java are both popular programming languages that have been around for many years. While they share some similarities, there are also some key differences between them. Syntax: One of the most obvious differences between Python and Java is their syntax. Python is known for its simple, readable syntax, which is designed to be easy to learn and use. Java, on the other hand, has a more complex syntax that requires more code to accomplish the same tasks. Performance: Java is generally faster than Python when it comes to execution speed. This is because Java code is compiled into bytecode, which can be executed directly by the Java Virtual Machine (JVM). Python, on the other hand, is an interpreted language, which means that each line of code is executed one at a time by the Python interpreter. Memory Management: Java manages memory through a process called Garbage Collection. This process automatically frees up memory that is no longer in use, which helps to prevent memory leaks ...

Cypress V/S Selenium

  Cypress V/S Selenium During my learning of Cypress, I noted down a few important differences between these tools. Documentation: Cypress Selenium Feature Cypress Selenium Language Support JavaScript Multiple languages including Java, C#, etc. Test Architecture Mocha test runner and Chai assertion library built-in Requires separate test frameworks and assertion libraries Browser Support Chrome, Firefox, Electron Multiple browsers including Chrome, Firefox, Safari, Edge, etc. Test Structure Built-in test runner and assertion library Needs separate test runners and assertion libraries Test Execution Faster execution Slower execution due to the use of WebDriver DOM Manipulation Native commands for DOM manipulation Needs to use JavaScriptExecutor for DOM manipulation Locators Cypress uses jQuery-like syntax for selecting elements Selenium uses various locating strategies such as XPath, CSS Selector, etc. Automatic Waits Automatically waits for commands to complete before moving...
