# The best-tested open source NestJS repos

11 public NestJS repos that SeeRepo read have 10 test files or more. immich-app/immich comes first: a test calls 54.9% of its routes.

How they're ranked: by the better of two shares, of their code files that some test imports directly or, with 20 routes or more, of their routes that some test calls; then by stars. That says what a test reaches, not which lines run. A repo enters with 10 test files or more and 20 code files or more.
