Node.js testing


This document is work in progress.

Getting started

To set up Node.JS testing, specify "node" as the environment in your config file:

var config = module.exports;

config["My tests"] = {
    environment: "node",
    tests: [

This config file will load all <something>-test.js in the same folder as the config file and all sub folders. Unlike browser tests, you don’t need to specify your source files with "sources". In fact, doing so will only make the tests slower, as the config file takes longer time to load. Instead, you do what you always do in Node.JS: require() the modules you use in the files where you need to use them:

var buster = require("buster");
var myLib = require("../lib/my-lib");

buster.testCase("A test case", {
    "test it": function () {

As we can see, we also need to require Buster.JS itself. The buster module provides all the core functionality such as test cases, assertions, and more.

Running tests

To run the tests, simply type:

buster test

Here’s the test output for the posix-argv-parser module:


See buster test –help for more information about the options you can pass to buster test.
