espower-coffee is a Node.js module loader that instruments power-assert feature into target CoffeeScript sources on the fly.
Pull-requests, issue reports and patches are always welcomed. See power-assert project for more documentation.

If your tests are located on 'test/**/*.coffee', just run mocha with --require 'espower-coffee/guess'
$ mocha --require 'espower-coffee/guess' test/**/*.coffee
You can set test directory in your package.json
{
"name": "your-module",
"description": "Your module",
"version": "0.0.1",
"directories": {
"test": "spec/"
},
...
}Then, run mocha with --require 'espower-coffee/guess'
$ mocha --require 'espower-coffee/guess' spec/**/*.coffee
Note: 'espower-coffee/guess' is inspired by intelli-espower-loader
If you want to configure more explicitly, put espower-coffee-loader.js somewhere in your project.
require('espower-coffee')({
// directory where match starts with
cwd: process.cwd(),
// glob pattern using minimatch module
pattern: '{src,test}/**/*.coffee',
// options for espower module
espowerOptions: {
patterns: [
'assert(value, [message])',
'assert.ok(value, [message])',
'assert.equal(actual, expected, [message])',
'assert.notEqual(actual, expected, [message])',
'assert.strictEqual(actual, expected, [message])',
'assert.notStrictEqual(actual, expected, [message])',
'assert.deepEqual(actual, expected, [message])',
'assert.notDeepEqual(actual, expected, [message])',
'assert.deepStrictEqual(actual, expected, [message])',
'assert.notDeepStrictEqual(actual, expected, [message])'
]
}
});Then, run mocha with --require option
$ mocha --require ./path/to/espower-coffee-loader spec/unit/some_test.coffee
We support Node under maintenance. In other words, we stop supporting old Node version when their maintenance ends.
This means that any other environment is not supported.
NOTE: If espower-coffee works in any of the unsupported environments, it is purely coincidental and has no bearing on future compatibility. Use at your own risk.
