A neutral, documentation-based benchmark axis for whether AI app builders commit to dependency and supply-chain hygiene, scored across v0, Lovable, Replit, Base44, and Bolt.new (August 2026).

As of July 2026, AI app builders increasingly claim to "test" the apps they generate, but that is not the same as handing you a re-runnable test suite you own. This proposed benchmark axis scores each builder on five documented sub-criteria and finds that agent-side verification is common while a persisted, developer-owned test suite is largely undocumented across the cohort.
First-build scores rate one generation. Most real work is the follow-up edit. We propose iteration fidelity: a five-part rubric, a repeatable protocol, and a provisional July 2026 cohort table.
