# The best-tested open source FastAPI repos

11 public FastAPI repos that SeeRepo read have 10 test files or more. harry0703/MoneyPrinterTurbo comes first: a test imports 84.6% of its code files.

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