Original Summary

I work on Midscene. One awkward UI test: submit a form, then check the success toast. By the time the check runs, the toast may already be gone. Midscene has startObserving() for this. Start recording before the action, stop afterward, and run the assertion against the recorded frames: ts const observer = await agent.startObserving(); await agent.aiAct('submit the form'); const observation = await observer.stop(); await observation.aiAssert('a success toast appeared during the process'); await observation.dispose(); The same approach is useful for banners and page transitions. It samples the screen, so a very brief event can still be missed; this isn't a frame-perfect game recorder. Midscene is open source. Model calls have their own cost.
