Jest features

  • Zero config. Works out of the box on most JavaScript projects without needing configuration.
  • Snapshot testing. Creates and compares snapshots of large objects inline or alongside tests.
  • Parallel isolation. Runs tests in separate processes for maximum performance and reliable global state.
  • Built-in code coverage. Generates coverage reports with the --coverage flag, no extra setup required.
  • Easy mocking. Custom resolver and Mock Functions API let you mock imports and spy on calls easily.
  • Rich assertions. Provides a comprehensive expect API with detailed failure messages.

NovaSynth by Noveum features

  • Synthetic callers with personas. Create AI callers with goals, moods, accents and interruptions to mimic real users.
  • Real SIP and LiveKit calls. Dial agents over Twilio, Plivo, Vobiz SIP or LiveKit audio for true latency and audio.
  • Batch matrix runs. Run combinatorial persona × scenario matrices in a single batch for coverage.
  • Concurrency & load testing. Scale up to 2,000 concurrent lines to measure agent capacity.
  • 30+ voice metrics scoring. Capture each call and score it with a suite of voice AI quality metrics.
  • Queue architecture. Async queue built on BullMQ, PostgreSQL and Redis enables parallel runs at scale.
