An asynchronous unit testing framework in under 40 lines of code.

Node Micro Test

MicroTest is an asynchronous testing framework built for Node.js. It's under 40 lines of code, and has no dependencies.

Create a folder called test/ in the root of your project directory.

Within this folder create .js testing files that look like this:

var equal = require('assert').equal;
exports.tests = {
    'true should be equal to true'function(finishedprefix) {
        equal(true, true, prefix + " that's weird, true should really be equal to true.");
        setTimeout(function() {
        }, 2000);
  • finished call this within your test, to indicate that all asynchronous actions have completed.
  • prefix contextual information about the test that you can print out with your assertions.

Just run the command micro-test from the root directory of your Node.js project.

  • npm install micro-test
  • micro-test
