QA: State Streaming — CrewAI (Flows)

Prerequisites

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

Test Steps

1. Basic Functionality

• Navigate to /demos/shared-state-streaming
• Verify data-testid="document-view" renders with heading "Document" and data-testid="document-char-count" reads 0 chars
• Verify the empty state says the output will stream into the document token by token
• Verify the chat input placeholder is "Ask me to write something..."
• Verify the suggestions "Write a short poem", "Draft an email", and "Explain quantum computing" are visible

2. Feature-Specific Checks

• Click "Write a short poem"
• While the run is active, verify data-testid="document-live-badge" appears and the document content grows progressively
• Verify data-testid="document-char-count" increases while content is streaming
• When the run completes, verify data-testid="document-content" contains the poem and the live badge disappears
• Click "Draft an email" and verify the document is replaced by the complete email rather than appended to the poem
• Verify the assistant sends a short confirmation after writing the document

3. Error Handling

• Attempt to send an empty message; verify it is a no-op
• Send a non-writing question; verify the turn completes without corrupting the current document
• Verify the browser console has no uncaught errors during the flow

Expected Results

• The document grows progressively while write_document arguments stream
• The final document persists in shared state after the run
• Subsequent writing requests replace the document cleanly
• No UI errors or broken layouts
