Test sets in RAG scenarios usually need to cover three types of cases: normal questions (to verify basic capability), edge-case questions (such as multi-hop reasoning and questions requiring synthesis across documents), and adversarial questions (such as cases where the retrieval source itself lacks the answer, or distracting documents are present); the latter two types are most likely to expose defects in the coordination between retrieval and generation.

UnverifiedThe recommended troubleshooting sequence for RAG systems is: first build a test set with ground-truth answers, check whether the retrieved chunks contain the answer for failed cases, and if retrieval is correct but generation fails, prioritize adjusting the prompt and context ordering before upgrading the model.74% similarUnverifiedPerturbation testing can refer to NLP robustness evaluation benchmarks (such as CheckList and AdvGLUE), which categorize perturbations into three types: character-level, lexical-level, and semantic-level.69% similarUnverifiedA RAG system should maintain a small regression test set (golden dataset) containing real questions and known answers, and run it every time the chunking strategy, embedding model, or prompt is modified, in order to catch regressions before launch.69% similarUnverifiedThe reasoning tier should be treated as a parameter to be tested rather than a default value; reasoning is a switch for handling difficult tasks, not a setting to be left permanently on.68% similarUnverifiedStandardized benchmark tests typically evaluate closed-ended questions and cannot fully reflect real-world performance in open-ended dialogue, creative writing, or complex multi-turn interactions.68% similar
