Selenium Automation Testing and Selenium Tool Package Drag and Drop Bug

A user picks a virtual object by grasping it and dragging it to another position or into another virtual object. This gesture is known as drag and drop. A known problem in Selenium Automation Testing causes the drag and drop action to occasionally fail (or, to be more precise, to fail in this order).

The author of this article, who also works as the QA Automation Lead at Flow Health, recently released the Selenium Tools package for Python, which makes it possible to perform bugged drag and drop in just a few lines (import + find elements + drag and drop itself) without having to delve too deeply into JavaScript or construct your own bicycle.

 

Why does Selenium's drag and drop functionality not work properly?

A: Well, it's not actually damaged. It's somewhat damaged. Drag and drop has its uses and its limitations. One of the primary committers of Selenium, David Burnes, stated that it is a problem for web items that contain a draggable attribute.

 

Does this bug only affect Selenium?

A: No, it was originally a WebDriver bug rather than a Selenium bug. When Selenium works with web components that have the droppable attribute, the WebDriver API receives requests from Selenium and doesn't respond to drop actions correctly. This indicates that any framework that makes use of WebDriver for web browser automation experiences this problem.

 

How does the workaround involving drag and drop operate?

A different method must be used to imitate this activity because Selenium uses WebDriver for web browser automation. JavaScript is the alternative solution that enables drag and drop. A specialised JavaScript script can be run in a browser to imitate such a difficult action. You may easily implement drag and drop functionality by providing the JavaScript code using Selenium's execute script method, which is available on all platforms (including Java and Python). You can also use tools that are developed on top of Selenium, like TestProject, which gives Selenium testing access to a large library of automation activities, including a Drag & Drop Addon and AI self-healing.

 

So the JavaScript code in the Selenium Tools package for Python just carries out that workaround?

A: Yes, you can import the Selenium Tools package anywhere drag-and-drop functionality is required but isn't supported by native Selenium tools by simply installing it as a dependency in your project. A WebDriver instance and draggable, droppable web components must be given in order to use the drag and drop functionality from the Selenium Tools package. I should also mention that you must only use components that CSS selectors have identified. Since XPath is not supported by the script that is provided, it only functions using CSS selectors.

 

What else does the Selenium Tools package currently offer besides drag and drop?

A: This package currently just contains the drag and drop workaround as a feature. I created it to assist others in resolving a problem I once encountered when doing drag and drop in a test case was essential. If any new beneficial features emerge, I'll absolutely include them. Any contributions in this area would be much appreciated because this programme is open source.

 

Why not just fix the bug itself instead of making a separate package for a drag-and-drop solution for Selenium?

A: Because it's a WebDriver bug, as I've already explained, WebDriver developers should solve it, but they haven't in a long time (more than 5 years already). David Burnes, a core committer for Selenium, and I had a conversation about incorporating the workaround into the software, but he advised against it. Because of this, I had to develop a unique package to assist the test automation community with this issue.

 

Conclusion

Here, in the Python Package Index, you can find more information about the Selenium Tools package.

Automation is bound to rule production activities in the future. It is held to propel efficiency as well as guarantee ROI. Given so, Selenium Automated Testing is bound to remain the tool of choice. It may have its own disadvantages; however, its benefits overshadow other tools, predominantly in three specific areas: cost, flexibility and parallel testing.
