Testing Flows

​

Why Test Your Flow?

• Accuracy: Validate edge conditions, tool integrations, and variables.
• User Experience: Simulate real user interactions to optimize responses.
• Debugging: Identify and fix errors in the flow logic or configurations.

​

How to Test a Flow

​

1. Open the Test Mode

1. Navigate to the Canvas Workspace.
2. Click on the Test Button (commonly located in the top-right corner).
3. A chatbot interface will open, allowing you to interact with your flow.

​

2. Simulate User Interactions

• Enter inputs as if you were a user.
• Observe the chatbot’s responses and the flow progression.
• Test specific scenarios to verify edge conditions, variable usage, and tool integrations.

​

3. Debugging with the Flow Preview

• While testing, use the Flow Preview to visualize the current node, path, and conditions being executed.
• Identify any nodes or edges that don’t behave as expected.

​

Key Features in Testing Mode

1. Real-Time Feedback:
   • See responses as they are generated.
   • Highlight issues in tool calls, conditions, or variable substitutions.
2. Flow Navigation:
   • View the active node and how the flow progresses.
   • Test rewinds and dynamic routing logic.
3. Adjust and Retry:
   • Make quick edits to nodes, tools, or conditions.
   • Retest the flow to verify fixes.

​

Testing Edge Cases

• Invalid Inputs: Test how the chatbot responds to unexpected user inputs.
• Tool Failures: Simulate API or tool errors and verify error handling.
• Unmatched Conditions: Ensure a default path exists for conditions that don’t match.

• If a user asks an unsupported question, the chatbot should gracefully fall back to a help or default response.

​

Example Testing Workflow

1. Start a test session from the Canvas Workspace.
2. Input queries such as:
   • “What can you do?”
   • “Cancel my subscription.”
3. Observe:
   • Chatbot responses.
   • Node transitions and edge conditions.
4. Debug:
   • Fix any incorrect responses or misrouted flows.
   • Retest until the flow behaves as expected.

​

Best Practices for Testing Flows

• Test Incrementally: Test small sections of your flow before combining them into a larger flow.
• Simulate Real Scenarios: Use realistic inputs to replicate user behavior.
• Validate All Paths: Ensure every edge and condition has been tested.
• Track Logs: Review error logs or debug information for troubleshooting.

​

Example: Customer Service Chatbot Testing

1. User greets the chatbot → Test the Start Node response.
2. User asks about pricing → Validate routing to the Pricing Node.
3. User cancels the inquiry → Test the Cancel Node’s response.
4. User enters invalid input → Ensure the chatbot redirects to clarification or fallback.
