 ### Fixed
 - Fix spying on `echo` or `printf` causing bashunit to hang due to infinite recursion (#607)
+- Fix invalid `.env.example` coverage threshold entry and copy `.env.example` to `.env` in CI test workflows so configuration parse errors are caught during automated test runs
 
 ## [0.34.1](https://github.com/TypedDevs/bashunit/compare/0.34.0...0.34.1) - 2026-03-20
