Best tested

The best-tested open source Gorilla repos

10 public Gorilla repos that SeeRepo read have 10 test files or more. pingcap/tidb comes first: a test imports 90.5% 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.
