testdouble for Karma

# karma-testdouble

This package is create as a convenient helper to load `testdouble.js` in karma
so that it doesn't have to go through a compilation step via `browserify` which
is slow.

## Installation

Install the plugin from npm:

```sh
npm install testdouble --save-dev
npm install karma-testdouble --save-dev
```

Add `testdouble` to the `frameworks` key in your Karma configuration:

```coffee
module.exports = (config) ->
  config.set

    # frameworks to use
    frameworks: ['mocha', 'testdouble']

    # ...
```

## Usage

You can use use `td` without doing an import.

For example, `performAction` is a function that will execute `load` when it is passed in:

```js
describe('performing basic sanity checks', function () {
  it("should check if load is called", function () {
  	let load = td.function('load')
    let event = {
      data: {}
    }
    performAction(event, load, {})
    td.verify(load(null))
  })
})
```

`td.verify` is used to ensure that load is executed with parameter of `null`.
