In your dependencies.js file export a function which returns an object literal of dependencies. Here you can use assert.extend() to create your own custom matchers.

module.exports = function (assert) {
  assert.extend({
    myCustomMatcher: function (a, b, message) {
      assert.equal(a, b, message)
    }
  })

  return {
    myDep: 1,
    otherDependency: 'hello'
  }
}

Spies are useful for hooking into functions and asserting that they have been called and with the correct parameters.

To work with spies just include spy in your test function's parameters.

var obj = { foo: function () { } }

'a spy test': function (spy) {
  var mySpy = spy.on(obj, 'foo')
  obj.foo('bar')
  mySpy.assert('bar')
}

Relies on promises to provide asynchronous tests. One can reject or fail the test or resolve/complete the test. Returning the promise is essential to mark the test as asynchronous and inform testla to wait for the test to finish.

'an async test': function (promise) {
  setTimeout(function () {
    promise.resolve(4)
  }, 500)

  return promise
}
