They are also known as add-ons or browser extensions and they are software programs that extend the functionality of a website browser. Plugins can be downloaded & installed from their browser’s third-party websites or official store

Plugins add a variety of features to a web browser like ad-blocking, language translators, password managers, social media sharing buttons, etc. They also are utilized to improve web development & testing like the Selenium IDE plugin for playing back and recording automated tests in Chrome and Firefox browsers.

However, it is significant to note that plugins also help introduce security risks to the browsing experience. Other plugins may get your personal information or track all your online activities, while others contain malware or other dangerous code that harms your computer or interferes with your privacy.

To guarantee a safe & secure browsing experience, it is recommended to install plugins from trusted sources only and to update them regularly to the latest versions. It’s a suitable practice to review the settings and permissions of each plugin before you install them, to be sure that they don’t have access to extra details than what’s necessary.

User Extensions

User extensions include custom JavaScript functions plus classes which could be added to Selenium IDE to lengthen its capabilities. They enable users to create their commands & do advanced operations which aren’t possible with in-built commands.

Furthermore, user extensions are added to Selenium IDE as external JavaScript files, that can be loaded by IDE utilizing the “Options” menu. The moment the user extensions are loaded, new commands can be utilized in Selenium IDE scripts same as in-built commands.

Other common examples of client extensions for Selenium IDE are:

  • Browser-specific actions: Client extensions can be utilized to perform browser-specific actions like interacting with the browser’s native dialogs or getting access to the browser’s APIs.
  • Data-driven testing: Client extensions can be utilized to read information from external sources, like databases or CSV files & utilize them to drive test cases.
  • Assertions: Custom assertions are created to approve specific elements or features of a webpage.
  • Custom wait conditions: Client extensions can be utilized to create a custom wait state that pauses the test script up to when a certain condition is met.

User extensions are a powerful tool that helps in creating improved test scripts in Selenium IDE. Moreover, it’s significant to ensure that extensions are maintained and tested to prevent any unexpected bugs or errors in the test scripts.
