VOice AI agent testing
VOice AI agent testing

Manual agent testing doesn’t scale.

AI behavior changes fast, and new model updates or data shifts can break logic you thought was stable.

Testing is manual, slow, and breaks with every prompt change

QA means writing a few test scripts in Notion, Excel or spreadsheets, it’s painful and impossible to scale

You only discover regressions when users complain

After deployment, issues like tool-call errors, latency spikes, or logic loops appear silently.

It’s hard to convince others the agent is actually ready for production

Stakeholders ask: ‘How confident are we this won’t break in the wild?’ and you don’t have data to show.

We don’t really know how the agent behaves across hundreds of scenarios

Your team can’t possibly test every edge case: ambiguous inputs, multi-turn confusion, API failures, long-context drift.

Simulate thousands of conversations, calls before launch

Simulate thousands of conversations, calls before launch

Simulated Scenarios – Run realistic multi-turn conversations to test your agent in varied situations.

Multi-Turn Chats – Support long back-and-forth dialogues and verify the agent’s performance at every step.

Context Retention – Verify the agent remembers and uses context

from earlier turns instead of forgetting important details.

Tool Call Checks

Ensure the agent invokes the right tools or APIs with the correct parameters during its tasks.

Interactive Debugging

Step through conversations in real-time and inspect each turn to quickly diagnose issues

Regression Prevention

Get early alerts when changes degrade your agent’s behavior, so you maintain high quality and confidence.

Seamless Integration

Plug into CI/CD and testing frameworks (like pytest/Jest) with minimal setup, in Python, TS, or Go.

The Agent Quality Platform

Unlike generic LLMOps tools or observability tools, LangWatch measures the real conversational agents with the right business metrics

Performance Analytics & ROI

Real business metrics tailored for conversational agents (escalation rate, first call resolution, NPS, latency, containment)

Agent Simulations

Realistic multi-turn, multi-thread testing in multiple scenarios before launch

Conversational-specialized Evaluations

ASR/TTS noise evaluation, intention detection accuracy, off-topic guardrail

Conversation Insights

Problem resolution rate, "I don't know" detection, topic categorization

Fix & Improvement Suggestions

AI-generated code and flow fixes via Git integration

Visualized conversation

Identify failure points and understand interaction patterns during testing
