Introduction: The New Frontier of Agentic AI Assurance
As organisations race to deploy Generative AI (GenAI) and Agentic AI systems, the need for robust, scalable, and trustworthy testing frameworks has never been greater. While GenAI models like chatbots have become mainstream, the emergence of Agentic AI—systems that plan, reason, and act autonomously—brings a new level of complexity and risk. This blog explores the GenAI testing process, key learnings from real-world pilots, and the critical gap that must be bridged to assure Agentic AI.
The GenAI Testing Process: A Step-by-Step Guide
1. Define Objectives and Scope
Start by clarifying the use case (e.g., ESG reporting chatbot, Wealth Management advisorbot etc) and the risks to be managed. What are the key metrics—accuracy, robustness, completeness? What are the regulatory and ethical requirements?
2. Develop Testing Metrics and Methodology
- Accuracy: Compare model outputs to ground truths, using both rule-based and human-in-the-loop (LLM-as-a-judge) approaches.
- Robustness: Test for consistency across multiple runs and scenarios, using metrics like cosine similarity.
- Completeness: Assess whether all sub-questions or components are addressed in the response.
3. Prepare Ground Truths
Curate authoritative answers, often with the help of subject matter experts (SMEs), to serve as the benchmark for evaluation.
4. Establish a Testing Environment
Set up secure infrastructure, access to relevant data, and tools for automated and manual evaluation.
5. Conduct Testing
Run the model through a battery of test cases, including binary, multi-class, and reasoning questions. Evaluate outputs for hallucinations, contradictions, and coverage.
6. Analyze Results
Use confusion matrices, overlap rates, and error analysis to identify strengths and weaknesses.
7. Implement Improvements
Refine prompts, retrain models, and iterate on the testing process to address identified issues.
8. Monitor and Maintain
Deploy continuous monitoring to catch drift, emerging risks, and compliance issues in production.
Key Learnings from GenAI Testing
- High Binary Accuracy, Low Multi-Class Performance:
GenAI chatbots often excel at yes/no questions (88%+ accuracy) but struggle with nuanced, multi-class distinctions (e.g., high/medium/low impact). - Hallucinations and Contradictions:
Even with strong ground truths, models can generate unsupported or contradictory statements. Hallucination rates of 17% and contradiction rates of 4.7% are not uncommon. - Defaulting to “Medium” and Lack of Justification:
When uncertain, models tend to default to “medium” or provide conclusive answers without sufficient evidence, undermining trust and auditability. - Governance and Monitoring Are Essential:
Embedding transparency, traceability, and human-in-the-loop oversight is critical for compliance and continuous improvement. - Cost Structure:
Testing costs could escalate very quickly; for comprehensive human-in-the-loop evaluation, with automated tools offering significant savings but requiring careful calibration.
The Gap: Why Agentic AI Testing Is a Different Beast
What is Agentic AI?
Agentic AI systems go beyond static input-output models. They plan, reason, and act autonomously—often chaining together multiple agents, tools, and data sources to achieve complex goals. Think of a digital assistant that not only answers questions but also books meetings, sends emails, and adapts its strategy based on feedback.
Why Is This Harder to Test?
- Workflow Complexity:
Agentic AI involves multiple interacting components (reasoning, routing, tool invocation, monitoring), each with its own failure modes. - Error Compounding:
Small errors in one step can cascade, leading to systemic failures. A 1% error rate per action can result in a 63% failure probability over 100 steps. - Emergent and Non-Deterministic Behaviors:
The system’s behavior can change based on environment, user input, or even previous actions—making exhaustive testing nearly impossible. - Exponential Growth in Test Cases:
Every new agent or workflow permutation multiplies the number of scenarios to test, quickly outpacing traditional QA resources.
The Agentic AI Testing Challenge: Best Practices
1. Modular and Risk-Based Testing
Test each agent and component individually before integrating. Use risk-based prioritization to focus on the most critical and high-impact workflows.
2. Simulation and Real-World Testing
Leverage simulation environments to model complex interactions, but also deploy in controlled real-world settings to catch issues that only emerge in practice.
3. Statistical and Adaptive Methods
Use statistical sampling, coverage metrics, and adaptive testing to ensure sufficient coverage without exhaustive permutation testing. Techniques like stratified sampling and metamorphic testing help target the riskiest areas.
4. Continuous Monitoring and Feedback Loops
Agentic AI systems require ongoing monitoring, anomaly detection, and escalation mechanisms to catch and correct errors in real time.
5. Human and Automated Evaluation
Combine automated tools (e.g., LLM-as-a-judge) with SME review for high-stakes decisions, ensuring both scalability and domain relevance.
6. Governance and Compliance
Expand AI governance frameworks to cover agent autonomy, usage boundaries, and prohibited interactions. Regular audits and transparent logging are essential.
Closing the Gap: Recommendations for Organisations
- Start with Modular Assurance:
Build up from GenAI best practices, but design your testing framework to handle modular, agentic workflows. - Invest in Automation and Tooling:
Use AI-driven testing tools to generate, execute, and analyse test cases at scale. - Prioritise by Risk and Impact:
Focus resources on the most critical workflows and components, using risk-based and data-driven prioritization. - Embrace Continuous Assurance:
Move from point-in-time testing to continuous monitoring and feedback, especially as agentic systems evolve in production. - Collaborate and Standardise:
Engage with industry groups and standards bodies to share best practices and develop common frameworks for agentic AI assurance.
Conclusion: The Future of (Agentic) AI Assurance
The journey from GenAI to Agentic AI is not just about more powerful models—it’s about fundamentally new ways of working, reasoning, and interacting with the world. Testing and assurance must evolve in lockstep, moving from static, point-in-time checks to dynamic, risk-based, and continuous assurance. By bridging the gap between GenAI and Agentic AI testing, organisations can unlock the full potential of autonomous systems—safely, responsibly, and at scale. Maybe more philosophical, but this is our last-chance to govern, regulate AI; next stop = AGI! It is my firm belief that Agentic AI systems will gain autonomy and agency (however much humans allow + cede). The human plight e.g. greed, megalomania, and other strifes will drive us to hand-over #Trust to increasingly sycophantic (manipulative?) autonomous and reasoning systems..
Ready to take your AI assurance to the next level? Start by rethinking your testing playbook—because the future of AI is agentic, and the risks (and rewards) are exponential.
