A software developer evaluated five tools for testing voice agent features, categorizing them into voice-testing specialists (Hamming, Coval, Cekura) and broader platforms with voice simulation capabilities (Future AGI, Vapi). The key differentiator was the ability to replay real failed calls as regression tests, a feature not offered by all tools that primarily generate synthetic calls. The developer ultimately kept two tools running: one for load testing and another for scenario-based CI, emphasizing the importance of testing voice-specific failure modes like barge-in and end-of-turn detection.
