What is unique about testing AI assistants?

AI assistants combine non-deterministic NLP outputs with strict business logic. Testing requires validating both layers: that the conversational AI responds accurately to user inputs, and that the underlying eligibility logic produces correct recommendations regardless of how the question is phrased.

How do you test NLP and conversational AI features?

QA engineers test conversational AI by submitting varied phrasings of the same question to verify consistent, accurate responses. Edge cases include ambiguous inputs, incomplete information, and conflicting eligibility criteria. The goal is to ensure the system guides users correctly even when their inputs are imprecise or unexpected.

How do you validate RAG-based AI systems?

RAG (Retrieval-Augmented Generation) systems retrieve documents before generating responses. Testing focuses on whether the retrieval step surfaces the correct source material, whether the generated response accurately reflects that material, and whether the system handles gaps in the knowledge base gracefully rather than hallucinating answers.

What does QA look like on a full-stack AI development project?

On this project, one QA engineer was embedded in a 7-person agile team alongside AI engineers, full-stack developers, a PM, and a UX designer. QA ran in parallel with development - covering functional flows, UI, eligibility logic validation, and conversational AI behavior - rather than as a separate phase at the end.

How do you test AI systems that improve over time?

Systems with continuous learning require regression testing after each model update. QA engineers establish behavioral baselines and verify that new training cycles improve accuracy without degrading previously correct responses.
