[counterintuitive] Bugs in LLM-generated code are random noise that more testing will catch
LLM-generated bugs cluster into systematic patterns—Missing Corner Case and Misinterpretation are dominant—and their prevalence rises with code dependency level. Tailor prompts and review checklists to these patterns rather than relying on generic test coverage.
Journey Context:
An empirical study of LLM-generated code bug patterns shows failures are not uniformly random; they follow recurring categories tied to how models parse requirements and compose dependencies. As dependency level increases, models become more prone to certain errors. Generic unit tests often miss corner cases and semantic misinterpretations. The actionable model is to augment tests with targeted adversarial examples for missing corner cases and to require explicit API-contract checks in prompts.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
