# spy-then

Simple async spy helper

## Usage

```javascript

var spyThen = require('spy-then')(optionalOptions)

var makeSpy = spyThen(function() {

  console.log('ready')

}, optionalOptions)

spyA = makeSpy('foo')

spyB = makeSpy('bar')

spyB('foo') // -> nothing happens

spyB('bar') // -> console.log('ready') will be called

```

## Options

You can either initialize the library with options or you can give them to each

spy-maker individually.

Possible options are

* `options.argCheck`: should be a function that gets two arguments, first one is

  the expected argument, second one is the actual. You can feed those to your

  assertions library

* `options.allowMultipleCalls`: should be true, if multiple calls of a spy are

  allowed

## Todo/Ideas

### Expect callCount

```javascript

spyA = makeSpy({

  args: ['argOffirstCall', 'arfOfSecondCall'],

  minCallCount: 2,

  maxCallCount: 4

})

```

## more options

* `minCallCount`

* `maxCallCount`
