QA: Tool-Based Generative UI — Mastra

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)

Test Steps

1. Basic Functionality

• Navigate to the gen-ui-tool-based demo page
• Verify the CopilotSidebar opens by default with title "Haiku Generator"
• Verify a placeholder haiku card is displayed on the main area
• Send a basic message via the sidebar
• Verify the agent responds

2. Feature-Specific Checks

Suggestions

• Verify "Nature Haiku" suggestion button is visible
• Verify "Ocean Haiku" suggestion button is visible
• Verify "Spring Haiku" suggestion button is visible

Haiku Generation (useFrontendTool)

• Click the "Nature Haiku" suggestion or type "Write me a haiku about nature"
• Verify a HaikuCard renders (data-testid="haiku-card") with:
  • Three Japanese text lines (data-testid="haiku-japanese-line")
  • Three English translation lines (data-testid="haiku-english-line")
  • A background gradient style applied to the card
• Verify the Japanese text contains actual Japanese characters (not Latin)
• Verify the English lines are a readable English translation

Image Display

• After haiku generation, verify an image renders (data-testid="haiku-image") if the agent provides an image_name
• Verify the image src points to /images/ with a valid filename from the predefined list

Multiple Haikus

• Generate a second haiku (e.g. "Ocean Haiku")
• Verify the new haiku card appears at the top
• Verify the previous haiku card is still visible below
• Verify the initial placeholder haiku is removed

3. Error Handling

• Send an empty message (should be handled gracefully)
• Verify no console errors during normal usage

Expected Results

• Sidebar loads within 3 seconds
• Agent responds and generates haiku within 10 seconds
• Haiku cards display with Japanese and English text
• Generated haikus stack with newest on top
• No UI errors or broken layouts
