Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Testpick is a CLI tool that uses runtime code coverage to select only the tests affected by a Git diff, solving the problem of static import graphs missing dynamic imports and runtime couplings. Its innovative combination of coverage mapping and incremental test selection makes multi-minute CI runs potentially much faster, while prioritizing safety by running more tests when uncertain.

Target audience: backend devs, frontend devs, devops
