# Best Practices

Testing is essential for successfully deploying your agent to production. Follow these recommended steps to ensure a robust deployment:

[**​**](https://docs.retellai.com/test/test-overview#step-1-llm-and-web-call-testing)**Step 1: LLM and Web Call Testing**

Validate and refine your agent’s behavior:

* Use the [LLM Playground](https://docs.retellai.com/test/llm_playground) to test conversation flows and responses
* Use [Web Call Testing](https://docs.retellai.com/test/test-web)
* Ensure accurate function calling and conversation handling

[**​**](https://docs.retellai.com/test/test-overview#step-2-phone-audio-testing)**Step 2: Phone Audio Testing**

Test your agent in phone environments:

* Place test calls to your agent
* Initiate outbound calls from your agent
* Validate performance with background noise and user interruptions

[**​**](https://docs.retellai.com/test/test-overview#step-3-limited-production-testing)**Step 3: Limited Production Testing**

Perform controlled testing in production:

* Deploy with a small sample size (5-10 calls)
* Use [monitor suites](https://docs.retellai.com/features/call-history-dashboard) to track performance
* Measure critical metrics including completion rates and user satisfaction

Scale your deployment strategically:

* Incrementally expand your user base
* Maintain continuous performance monitoring
