Episode notes
Natural Language Tests Run By An AI Agent
- Journeys uses Gemini to turn plain English test specs into adaptive UI actions without writing code.
- The agent reasons over screenshots and UI hierarchy to follow and maintain end-to-end user journeys.
Multimodal Context Powers Reliable Actions
- Journeys combines pixels and the UI hierarchy as multimodal inputs to Gemini for better decisions.
- That multimodal context is essential for the agent to know what actions to take next on a screen.
Thirty-Second Clock App Demo
- Adarsh wrote a Tokyo-clock test in plain English and Gemini performed the steps and validated the time difference.
- The results included Gemini's reasoning showing the math used to assert the Tokyo time was accurate.
