## Recommended Testing Workflow

<Steps>
  <Step title="Phase 1: Development Testing">
    **Tool:** LLM Playground

    * Iterate on prompts and conversation flows
    * Debug function calling logic
    * Test edge cases interactively
    * Validate dynamic variables
  </Step>

  <Step title="Phase 2: Quality Assurance">
    **Tool:** LLM Simulation Testing

    * Create comprehensive test scenarios
    * Run regression tests after changes
    * Validate success metrics
    * Ensure consistent performance
  </Step>

  <Step title="Phase 3: Production Validation">
    **Tool:** Web / Phone Call Testing

    * Test actual voice interactions
    * Verify audio quality and latency
    * Check telephony features
    * Validate real-world performance
  </Step>

  <Step title="Phase 4: Continuous Testing">
    **Tool:** Batch Testing (Simulation)

    * Set up automated test suites
    * Monitor agent performance over time
    * Catch regressions early
    * Maintain quality standards
  </Step>
</Steps>

<Tip>
  Create a test checklist covering all critical paths before each deployment. Include both happy paths and edge cases.
