The best-tested open source Express repos
11 public Express repos that SeeRepo read have 10 test files or more. apache/superset comes first: a test imports 61.3% 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.
