Implementation of (Un)commonJS unit test runner.

Testing

In order to make your package testable from npm you should:

  • Create a directory in your package root.
  • Define test directory in package descriptor under directories section.
  • Define test script in package descriptor under scripts section.
  • Define dependency on this package (It's name is "test" in npm registry).
  • Write your tests
  • Test your package by running all tests npm test or run individual tests node ./path/to/test/group.js

Example

package.json

{
  "name": "mypackage",
  "version": "0.7.0",
  "description": "Sample package",
  "scripts": { "test": "node test/all.js" },
  "devDependencies": { "test": ">=0.0.5" }
}

Async test

// if test function expects second named argument it will be executed
// in async mode and test will be complete only after callback is called
exports['test my async foo'] = function(assert, done) {
  var http = require('http')
  var google = http.createClient(80, 'www.jeditoolkit.com')
  var request = google.request('GET', '/', {'host': 'www.jeditoolkit.com'})
  request.end()
  request.on('response', function (response) {
    assert.equal(response.statusCode, 302, 'must redirect') // will log result
    response.setEncoding('utf8')
    response.on('data', function (chunk) {
      assert.notEqual(chunk, 'helo world', 'must be something more inteligent')
      done() // telling test runner that we're done with this test
    })
  })
}

if (module == require.main) require('test').run(exports)

Sync test

// using assert passed to the test function that just logs failures
exports['test that logs all failures'] = function(assert) {
  assert.equal(2 + 2, 5, 'assert failure is logged')
  assert.equal(3 + 2, 5, 'assert pass is logged')
}

if (module == require.main) require('test').run(exports)

Fast fail

// using nodejs's build in asserts that throw on failure
var assert = require('assert')

exports['test that stops execution on first failure'] = function() {
  assert.equal(2 + 2, 5, 'assert fails and test execution stop here')
  assert.equal(3 + 2, 5, 'will never pass this since test failed above')
}

if (module == require.main) require('test').run(exports)

Custom assertions

var AssertBase = require('assert').Assert
var AssertDescriptor = {
  constructor: { value: Assert },
  inRange: { value: function (lower, inner, upper, message) {
    if (lower < inner && inner < upper) {
      this.fail({
        actual: inner,
        expected: lower + '> ' + ' < ' + upper,
        operator: "inRange",
        message: message
      })
    } else {
      this.pass(message);
    }
  }, enumerable: true }
}
function Assert() {
  return Object.create(AssertBase.apply(null, arguments), AssertDescriptor)
}

// bundling custom asserts with test suite
exports.Assert = Assert
exports['test with custom asserts'] = function(assert) {
  assert.inRange(2, 3, 5, 'passes assert and logs')
  assert.equal(3 + 2, 5, 'assert pass is logged')
}

if (module == require.main) require('test').run(exports)
