Thorough testing is crucial for building reliable AI phone agents. UponAI provides multiple testing methods, each designed to validate different aspects of your agent’s behavior and performance.

​
Available Testing Methods

1. LLM Playground

Purpose: Interactive text-based testing for rapid iteration and debugging.Key features: Real-time conversation testing, function call visualization, variable inspection, prompt debugging.Best for: Initial development, prompt refinement, debugging specific conversation paths.

2. LLM Simulation Testing

Purpose: Automated testing with predefined scenarios for consistent quality assurance.Key features: Batch testing, success metrics and scoring, scenario templates, regression testing.Best for: Quality assurance, regression testing, validating changes before deployment.

3. Web Call / Phone Call Testing

Purpose: Real-world testing with actual voice interactions to validate audio performance.Key features: Voice quality and latency testing, interruption handling, background noise, DTMF and telephony features.Best for: Final validation, voice quality testing, production readiness checks.
