QA: Read-Only Agent Context — Google ADK

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)
• Agent readonly_state_agent_context is mounted on the ADK server (see src/agents/registry.py)

Test Steps

1. Basic Functionality

• Navigate to the readonly-state-agent-context demo page
• Verify the "Agent Context" card is visible (data-testid="context-card")
• Verify the description text references useAgentContext: "Edit fields below and watch the data flow into the agent. The agent can read this context, but cannot modify it."
• Verify the popup chat renders in the corner with placeholder "Ask about your context..."
• Send a basic message (e.g. "Hello") via the chat
• Verify the agent responds with a text message

2. Feature-Specific Checks

Initial Context State

• Verify the Name input (data-testid="ctx-name") defaults to "Atai"
• Verify the Timezone dropdown (data-testid="ctx-timezone") defaults to "America/Los_Angeles"
• Verify the Timezone dropdown offers: America/Los_Angeles, America/New_York, Europe/London, Europe/Berlin, Asia/Tokyo, Australia/Sydney
• Verify the Recent Activity checkboxes list: "Viewed the pricing page", "Added 'Pro Plan' to cart", "Watched the product demo video", "Started the 14-day free trial", "Invited a teammate"
• Verify two activities are checked by default: "Viewed the pricing page" and "Watched the product demo video"
• Verify the Published Context JSON preview (data-testid="ctx-state-json") shows { "name": "Atai", "timezone": "America/Los_Angeles", "recentActivity": [...] }

Suggestions

• Verify "Who am I?" suggestion is visible
• Verify "Suggest next steps" suggestion is visible
• Verify "Plan my morning" suggestion is visible

Agent Reads User Name (useAgentContext)

• Click the "Who am I?" suggestion (or ask "What is my name?")
• Verify the agent response addresses the user as "Atai"
• Edit the Name input (data-testid="ctx-name") to "Jamie"
• Verify the Published Context JSON updates to show "name": "Jamie"
• Ask "What is my name?" again
• Verify the agent now responds with "Jamie" (not "Atai")

Agent Reads Timezone

• Change the Timezone dropdown (data-testid="ctx-timezone") to "Asia/Tokyo"
• Verify the Published Context JSON updates to "timezone": "Asia/Tokyo"
• Click the "Plan my morning" suggestion
• Verify the agent's response references Tokyo / JST / Asia/Tokyo when discussing the time

Agent Reads Recent Activity

• Uncheck all default activities, then check only "Started the 14-day free trial" and "Invited a teammate"
• Verify the Published Context JSON shows the new recentActivity array
• Click the "Suggest next steps" suggestion
• Verify the agent's response references the trial and/or invited-teammate activities (not the pricing page or demo video)

3. Error Handling

• Clear the Name input to an empty string and ask "What is my name?" — agent should handle gracefully (no crash)
• Send an empty chat message — input should be rejected without error
• Verify no console errors during normal usage
• Verify the agent cannot modify context values (Name / Timezone / Activity checkboxes stay user-controlled)

Expected Results

• Context card and chat load within 3 seconds
• Agent responds within 10 seconds
• Every change to Name / Timezone / Recent Activity reflects in the Published Context JSON immediately
• Agent responses reflect the CURRENT context values on every turn (no stale context)
• No UI errors or broken layouts
