A progress bar is a graphical control that shows how much of a long-running operation has finished. In a URL stress-test application, it updates after each 1% of completed requests so users can track activity without guessing whether the interface is still working. section 7.4.2
A practical progress indicator supports the surrounding application by:
- Displaying completion while asynchronous web requests run. section 7.4.2
- Keeping the Tkinter interface responsive while asyncio performs work in another thread. section 7.4.2
- Working alongside cancellation controls so the user can stop the operation. section 7.4.2
URL stress-test interface
A GUI accepts a URL and request count, starts the stress test when the user submits it, and advances the progress bar as requests finish. The Tkinter event loop remains in the main thread while asyncio runs in a separate thread and sends progress updates back to the interface. section 7.4.2
