SIMULATION
Test your agent against 10,000 users before the first real one shows up.
Spin up persona-driven simulated users — frustrated, confused, adversarial, multilingual, indecisive — and run them against your agent in parallel multi-turn conversations. Find the failure modes before your customers do.
Persona-driven simulated users
Impatient, non-native speaker, adversarial, indecisive, domain-novice
Real multi-turn conversations
Simulated users react to your agent's actual responses, not scripted Q&A
Trajectory-level scoring
Did the agent reach the goal? Not just "was each turn fluent?"
Parallel runs at scale
Thousands of scenarios overnight, every one traced and evaluated
Edge-case generation
Auto-synthesize scenarios that target known weak spots
Same evaluators, pre-prod and prod
Whatever scores production also scores simulation
Regression suites from real failures
Promote any production bug into a permanent simulated test
Tool, RAG, and guardrail coverage
Verify every tool path, retrieval branch, and policy boundary
Simulation explained
Unit tests catch the bugs you imagined. Simulation catches the ones you didn't.
The hardest agent bugs live in multi-turn dynamics: a user pushes back, the agent capitulates and bypasses a policy. A non-native speaker phrases a refund request three different ways, and only one of them triggers the right tool. An impatient user types "hello?? hello??" three times and the agent escalates to a human when it didn't need to. None of these show up in your dev test set.
Netra spins up persona-driven simulated users who actually converse with your agent — pushing back, going off-topic, asking the same thing five different ways — the way real users do. Define a persona ("frustrated customer, third support call this week, wants escalation") and a goal ("get a refund processed"). Netra runs the full conversation, traces every turn, and scores whether the agent achieved the goal — not just whether each turn was fluent.
Run a thousand scenarios in parallel overnight. Every conversation is traced and evaluated with the same evaluators you use in production, so simulation scores are directly comparable to live performance. Promote any production failure into a permanent regression test in your simulation suite — the same bug never ships twice.
