TestMu AI’s State of AI in Quality Engineering 2026 report says 81 % of software teams have integrated code or tests generated by AI that they don’t completely understand. Only 41 % run any automated checks on that AI output before it goes live, while 44 % report a rise in defects reaching production. The survey also shows 97 % of teams already use or plan to use AI for testing, but most still depend on manual review.

## The facts

- 81 % of teams have integrated AI‑generated code they don’t fully understand – TestMu AI report
- 44 % see more production defects as AI‑written code usage grows – same report

## Why it matters

Developers may face higher bug rates unless they adopt systematic verification of AI‑generated code.
