browser support

Minimal BDD test runner that plays along nicely with Browserify.


  • Not-A-Framework: Hi-five should let you, the programmer, lead the way and define how testing should be done. Bring your own reporters & assertion libraries.

  • Run anywhere: Hi-five should run in any JS VM that supports at least the ECMAScript 3 specification.

  • Easy to integrate: Hi-five should be easy to integrate with any CI or other system.

  • Support async: Hi-five should support asynchronous tests as first-class.


var spec   = require('hifive')()
var assert = require('assert')
spec('λ compose', function(it) {
  it('compose(f, g)(x) should be the same as f(g(x))', function() {
    assert.strictEqual(f(g(x)), compose(f, g)(x))


$ node run test.js
Success. 1/1 tests.


The easiest way is to grab it from NPM. If you're running in a Browser environment, you can use Browserify

$ npm install hifive

Using with CommonJS

If you're not using NPM, Download the latest release, and require the hifive.umd.js file:

var hifive = require('hifive')

Using with AMD

Download the latest release, and require the hifive.umd.js file:

require(['hifive'], function(hifive) {
  ( ... )

Using without modules

Download the latest release, and load the hifive.umd.js file. The properties are exposed in the global hifive object:

<script src="/path/to/hifive.umd.js"></script>

Compiling from source

If you want to compile this library from the source, you'll need Git, Make, Node.js, and run the following commands:

$ git clone git://
$ cd hifive
$ npm install
$ make bundle

This will generate the dist/hifive.umd.js file, which you can load in any JavaScript environment.


You can read the documentation online or build it yourself:

$ git clone git://
$ cd hifive
$ npm install
$ make documentation

Then open the file docs/index.html in your browser.

Platform support

This library assumes an ES5 environment, but can be easily supported in ES3 platforms by the use of shims. Just include es5-shim :)
