mocha-traceur

A Mocha plugin that compiles JavaScript files through the Traceur transpiler, enabling ES6 (ES2015) features for test files. Version 2.1.0 is the current stable release, depending on 'traceur-runner' for stack traces and optional dependency compilation. It operates via Mocha's --compilers flag. Key differentiator vs alternatives like babel-register: focused solely on Traceur, with no dependency compilation by default, making it lightweight but restrictive. The package is maintained infrequently; latest release 2.1.0 is several years old. Does not bundle Traceur itself, requiring a separate install.
