node.js - Tell Mocha to use CoffeeScript files by default -

i'm trying set testing in mocha application i'm writing using zappa.js. far i've been following this tutorial, , converting need js coffeescript.

however i'm little stuck trying run tests. have makefile, looks this:

reporter = dot  test:   @node_env=test ./node_modules/.bin/mocha \     --reporter $(reporter) \  .phony: test 

and i've set package.json file run tests so:

{   "scripts": {     "test": "make test"   } } 

the issue i'm finding that, because i'm trying write mocha tests using coffeescript well, mocha not pick of tests in "test/" folder when run "npm test". know fact can tell mocha run .coffee files using following in terminal (which works):

mocha --compilers coffee:coffee-script 

what want know how go telling mocha use coffeescript files default?

ok managed find way solve own question, thought i'd share in case else need this.

note: coffeescript 1.7+ --require coffee-script needs changed --require coffee-script/register

the solution instead create cakefile opposed makefile, looks this:

#cakefile  {exec} = require "child_process"  reporter = "min"  task "test", "run tests", ->   exec "node_env=test     ./node_modules/.bin/mocha     --compilers coffee:coffee-script     --reporter #{reporter}     --require coffee-script     --require test/test_helper.coffee     --colors     ", (err, output) ->       throw err if err       console.log output 

and change package.json this:

#package.json  {   "scripts": {     "test": "cake test"   } } 

finally had install coffeescript project using:

npm install coffee-script 

and create file test/test_helper.coffee, contains global declarations tests.
