TL;DR
Scenario-based testing for agentic systems validates end-to-end behavior across realistic user journeys, combining automated evaluators, human review, and granular node-level checks to improve reliability, safety, and performance in production. Use Maxim AI’s simulation, evaluation, and observability stack to design scenarios, run evals at session/trace/node levels, and continuously monitor using alerts and curated datasets. See foundational guidance in Maxim AI and the Docs for implementation details.
Scenario-Based Testing for Agentic Reliability
Scenario-based testing treats AI agents as goal-driven systems that operate across multi-step flows. The focus shifts from single-response accuracy to whether tasks complete successfully under realistic constraints, inputs, tools, and context.
• Define tasks and user personas, then model the full interaction trajectory across steps, tools, and decisions.
• Evaluate at multiple granularities: entire sessions, traces, and specific nodes (e.g., tool calls, generations, retrievals) to pinpoint failure modes, as supported in the Online Evaluation .
• Combine automated evaluators with human annotation to capture nuance, align with user preferences, and validate task outcomes.
• Curate datasets from production logs and evaluations to strengthen future tests and fine-tuning.
This approach aligns with practical guidance from Maxim’s platform for simulation, testing, and monitoring, including prompt tooling, RAG retrieval checks, and CI/CD integration via test runs. Explore the platform overview in the Docs and product pages linked throughout.
Designing Robust Agentic Scenarios
Start with clear objectives and measurable outcomes, then instrument every decision point.
• Scenario objectives: Define task success criteria (e.g., “resolve billing issue,” “answer policy question”), expected tool usage, and guardrails for safety and grounding. For security considerations like prompt injection risks, see the reference article on Maxim AI.
• Inputs and context: Include edge cases, ambiguous queries, and adversarial prompts; attach dynamic context sources in prompts to fetch real retrieval chunks.
• Flow instrumentation: Log spans and nodes for generations, retrievals, and tool executions. Evaluate nodes using SDK logger methods to attach evaluators and variables.
• Multi-agent routing: Build workflows that classify and route queries (e.g., Account/Billing/Returns/FAQ) and connect sub-agents to a final node.
Use Maxim’s experimentation playground to iterate prompts, attach tools, and version changes, then scale evaluation runs across datasets. The full documentation index is available at the Docs.
Running Evals: Session, Trace, and Node-Level
Agentic testing benefits from layered evaluation strategies that quantify quality, safety, and performance.
• Offline prompt tests: Configure datasets, evaluators, and side-by-side reports to analyze expected vs. actual outputs.
• Tool-call accuracy: Validate that agents choose correct tools and arguments at scale with statistical evaluators.
• Retrieval quality: Measure precision, recall, and relevance of context, and inspect retrieved chunks in detail.
• Human-in-the-loop: Add human evaluators for nuanced ratings and corrected outputs, with email-based workflows for external SMEs or report-column annotation for internal teams.
• CI/CD automation: Integrate prompt evals with GitHub Actions to enforce quality gates during development.
• Observability and alerts: Continuously evaluate production logs with filters and sampling, then configure Slack/PagerDuty notifications for performance and quality thresholds.
All workflows and reports can be customized, pinned, filtered, and shared via read-only links, making collaboration across engineering and product teams efficient.
Conclusion
Scenario-based testing is essential for trustworthy agentic AI. By modeling realistic tasks, instrumenting every step, and combining automated and human evaluations, teams can identify root causes, prevent regressions, and ship reliable agents faster. Maxim AI’s platform provides end-to-end capabilities—experimentation, simulation, evals, and observability—to operationalize scenario testing across pre-release and production environments. Learn more on Maxim AI and explore the full Docs to implement this practice with rigor.
FAQs
• What is scenario-based testing for AI agents?
▫ Validates complete task flows across multi-step interactions, tools, and context, measuring outcomes at session, trace, and node levels.
• How do I evaluate tool-call correctness at scale?
▫ Use statistical evaluators to compare expected tool calls and arguments against outputs;.
• How can I measure retrieval quality in agent pipelines?
▫ Attach context sources, run tests with retrieval evaluators (precision/recall/relevance), and inspect chunk details in reports
• Can human reviewers be added without platform seats?
▫ Yes, email-based human annotation allows external SMEs to rate entries via a separate dashboard; see Human Annotation (url://84).
• How do I integrate evals into CI/CD?
▫ Configure GitHub Actions with workspace IDs, datasets, and evaluators to run prompt tests automatically;
• How do I monitor quality in production?
▫ Enable auto evaluation on logs with filters and sampling, set alerts for performance/quality thresholds via Slack/PagerDuty, and curate datasets from logs.
