Live debugging
Mobitru provides a powerful Live Debugging feature that enables users to efficiently monitor and troubleshoot automated tests across multiple browsers in real time.
With this feature, you have:
- Review Test Execution in Real Time: watch your tests as they run live on different browsers, allowing for immediate feedback and faster issue detection
- Interactive Debugging: take manual control of the browser session to interact with the application, explore and manipulate the DOM structure, and validate UI elements directly
- Access Browser DevTools: open integrated DevTools to inspect network traffic, review JavaScript console logs, and analyze errors for comprehensive debugging
How It Works
Prerequisite:
- Start any of the Selenium or Playwright tests.
No special configuration is needed to use live debugging.
Simply start your Selenium or Playwright tests, and an ongoing session will automatically appear in the Desktop tab on Mobitru.

Review the DOM structure
Every browser has developer tools included, which can be used for accessing the DOM structure.
