Checking for the current loading status of a JavaScript file: How it's done

Currently, I am automating the GUI of my website using Selenium (RobotFramework). However, I have encountered an issue:

Occasionally, when my automation script clicks on an element such as a button or link that is supposed to trigger an action, nothing happens. Interestingly, this issue seems to occur randomly. Manual testing shows that the functionality works consistently. One possible reason could be that in slower machines or environments, this problem occurs more frequently.

I suspect that this issue may stem from the JS not being fully loaded yet or perhaps an "action binding" with each element has not been completed.

Questions for consideration: - Is there a method to determine if all JS calls have been completed? - Regarding action binding, how can we verify if it has been bound successfully?

If you have any alternative solutions, please feel free to share them.

Answer №1

Have you ever wondered what loads last on a webpage? It's a simple task to discover this using the Developer Tools available in your preferred browser.

Once you identify the final item to load, you can easily implement a Wait Until Keyword (there are numerous variations) to ensure that the item appears as expected before proceeding with your testing. By setting the appropriate timeout length and interval, you can effectively manage the time/performance overhead.

Wait Until Element Is Visible   id=lastElement    10    The final element did not show up on the screen within the allocated timeout period

- be sure to check out the documentation for additional examples and keyword options
