buster-coffee npm

Buster.JS extension that automatically compile CoffeeScript files before running tests

7 years after


Build Status

An extension for Buster.JS to automatically compile your CoffeeScript files before running tests.


Install from npm:

npm install buster-coffee

Then add it to your buster.js config file:

config["My tests"] = {
  // ...
  extensions: [require("buster-coffee")]
  // ...


The extension has no configuration options.

Example web project

See the demo/ dir for an example project using Buster.JS and buster-coffee to test a function that is implemented in CoffeeScript, using tests written in CoffeeScript.

Node.js and require()

Currently, buster-coffee does not work with files that are to be included using require(). buster-coffee never writes any files to disk, while require() explictly looks for the files it will include on disk. Because of this, buster-coffee has limited use for Node.js development in CoffeeScript.

AMD and CoffeeScript

If you are using buster-amd, you don't need buster-coffee to compile your CoffeeScript files. All you need to do is set up buster-amd's pathMapper to prefix CoffeeScript files with cs! and remove the .coffee suffix. Here's a naive implementation to get you going:

config["My tests"] = {
  // ..
  extensions: [require("buster-amd")],
  "buster-amd": {
    // Load tests written in CoffeeScript as AMD modules
    pathMapper: function (path) {
      return "cs!" + path.replace(/^\//, "").replace(/\.coffee$/, "");
  // ..
