QA: Shared State (Reading) — LangGraph (Python)

Prerequisites

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

Test Steps

1. Basic Functionality

  • Navigate to the shared-state-read demo page
  • Verify the recipe card form loads (data-testid="recipe-card")
  • Verify the CopilotSidebar opens by default with title "AI Recipe Assistant"
  • Send a message via the sidebar
  • Verify the agent responds

2. Feature-Specific Checks

Initial Recipe State

  • Verify the recipe title input shows "Make Your Recipe"
  • Verify the cooking time dropdown defaults to "45 min"
  • Verify the skill level dropdown defaults to "Intermediate"
  • Verify the default ingredients are displayed:
    • Carrots (3 large, grated) with carrot emoji
    • All-Purpose Flour (2 cups) with wheat emoji
  • Verify the default instruction is displayed: "Preheat oven to 350°F (175°C)"

Suggestions

  • Verify "Create Italian recipe" suggestion is visible
  • Verify "Make it healthier" suggestion is visible
  • Verify "Suggest variations" suggestion is visible

Recipe Editing (Local State)

  • Edit the recipe title and verify it updates
  • Change the skill level dropdown and verify it updates
  • Change the cooking time dropdown and verify it updates
  • Toggle a dietary preference checkbox (e.g. "Vegetarian") and verify it's checked
  • Click "+ Add Ingredient" (data-testid="add-ingredient-button") and verify a new empty row appears
  • Edit an ingredient name and amount
  • Remove an ingredient by clicking the "x" button
  • Click "+ Add Step" and verify a new instruction row appears
  • Edit an instruction and verify it saves
  • Remove an instruction by clicking the "x" button

AI-Powered Recipe Updates (useAgent with shared state)

  • Click "Create Italian recipe" suggestion
  • Verify the agent updates the recipe title, ingredients, and instructions
  • Verify the ping indicator appears on changed sections
  • Verify the "Improve with AI" button (data-testid="improve-button") changes to "Please Wait..." while loading
  • Click "Improve with AI" and verify the recipe is enhanced

Agent Reads Frontend State

  • Edit the recipe (change title, add ingredients)
  • Ask the agent "What recipe am I making?"
  • Verify the agent's response references the current recipe state

3. Error Handling

  • Send an empty message (should be handled gracefully)
  • Verify no console errors during normal usage
  • Verify the "Improve with AI" button is disabled while loading

Expected Results

  • Recipe card and sidebar load within 3 seconds
  • Agent responds within 10 seconds
  • Recipe state syncs bidirectionally between UI and agent
  • Ping indicators highlight changed sections
  • No UI errors or broken layouts
