Datasets for simulation define the scenarios you want to test—multi-turn conversations with specific goals, user personas, and success criteria. Unlike single-turn evaluation datasets, simulation datasets create dynamic, goal-oriented conversations that reflect real-world user interactions.

Why Simulation Datasets Matter

Simulation datasets transform simple Q&A testing into realistic conversation testing:

Dataset Dashboard

Navigate to Evaluation → Datasets from the left navigation panel. Filter by Multi turn type to see simulation datasets. Simulation Datasets Dashboard Each card displays the following fields:

Creating a Multi-Turn Dataset

Click the Create Dataset button in the top right corner of the Datasets page.

Configure Basics

Import from traces and CSV import for multi-turn datasets are coming soon.

Configure Scenario

Scenario ConfigurationDefine the simulation scenario with the following fields:Scenario Goal — Describe what the simulated user is trying to achieve. This becomes the goal that drives the conversation.
Behavior Instructions (Optional) — Provide guidance on how the simulated user should behave.
Max Turns — Choose the maximum number of conversation turns (1-10):
  • Lower (1-3): Quick interactions like single-question support
  • Medium (4-6): Standard support conversations
  • Higher (7-10): Complex, multi-step problem resolution
The simulation stops when the goal is achieved, the max turns limit is reached, or the scenario is abandoned.User Persona — Choose how the simulated user behaves emotionally:Provider and Model — Choose the LLM provider and model that will generate simulated user responses (e.g., OpenAI / GPT-4.1).
Use consistent, capable models (GPT-4, Claude Sonnet) for realistic user simulation.

Add User Data and Facts

User Data and Facts ConfigurationSimulated User Data — Provide context data that the simulated user can reference during the conversation. Available in Table, JSON, or Plain Text format.Example (Table):Example (JSON):
Fact Checker — Specify facts that the agent MUST communicate correctly. These are used by evaluators to verify accuracy.Example (Table):Example (JSON):
JSON Validation: When using JSON format, ensure there are no duplicate keys. The system validates JSON structure before allowing you to proceed.

Select Evaluators

Evaluator SelectionSelect evaluators from Netra’s library of session-level evaluators across two categories:Recommended Evaluators:
  • Agentic: Goal Fulfillment, Information Elicitation
  • Quality: Factual Accuracy, Conversation Completeness, Guideline Adherence
Configure variable mappings to connect evaluator inputs to your data:
  • Scenario fields: Goal, persona, user data
  • Agent response: What the agent said in each turn
  • Conversation metadata: Turn index, conversation history
  • Execution data: Latency, tokens, model

Configure Evaluators

Configure EvaluatorsWhen you select evaluators from the library, Netra clones them and adds them to My Evaluators. Configure each cloned evaluator:
  • Rename (optional) — Rename any evaluator to match your use case (e.g., “Refund Goal Fulfillment” instead of “Goal Fulfillment”)
  • Select Provider and Model — For each evaluator, choose the provider and model that will run the LLM-as-Judge evaluation (e.g., OpenAI / GPT-4.1)
Review all configurations, then click Create Dataset to finalize. Your simulation dataset is now ready to run.

Running a Simulation

Once your dataset is configured, you can run simulations:
1

Get Dataset ID

Open your dataset and copy the Dataset ID displayed at the top of the page.Dataset ID
2

Trigger Simulation

Use the Dataset ID in your simulation code. The simulation runs automatically through the Netra SDK.
3

View Results

Monitor progress and results in Test Runs.
Simulations execute automatically when the associated code is triggered. You don’t need to manually start each run—just ensure your agent code is integrated with Netra.

Best Practices

Crafting Effective Scenarios

  • Be specific: “Get a refund for a damaged product” is better than “Ask about returns”
  • Include context: Provide enough detail for realistic simulation (order details, timeline, issue description)
  • Include edge cases: Create scenarios that challenge your agent’s boundaries

Choosing User Personas

  • Neutral: Best for baseline performance testing
  • Friendly: Tests whether your agent maintains professionalism even when not challenged
  • Frustrated: Critical for customer support agents—tests patience and de-escalation
  • Confused: Tests clarity and explanation quality
  • Custom: Use for industry-specific personas (technical users, non-native speakers, etc.)

Defining User Data

  • Provide realistic data: Use representative order numbers, dates, and values
  • Include edge cases: Test with missing fields, unusual values, or conflicting data
  • Keep it relevant: Only include data that matters for the scenario
  • Use consistent formats: Standardize date formats, currency, and naming

Setting Fact Checkers

  • Focus on critical facts: What MUST the agent communicate correctly?
  • Be precise: “5-7 business days” is better than “about a week”
  • Test compliance: Include regulatory or policy-critical information
  • Verify, don’t duplicate: Don’t repeat information already in user data
