gulp-livescript-istanbul

Istanbul unit test coverage plugin for gulp, covering livescript and javascript.

Allows for in-place testing and coverage of livescripts files without the need for compiling and linking to the compiled source.

Displays coverage report in livescript, thanks to source map support in livescript@1.4.0

Inspired by gulp-coffee-istanbul & istanbul-traceur

Works on top of any Node.js unit test framework.
