Mocking ArrayAccess with prophecy in phpspec

MyThing.php

<?php

class MyThing
{
    private $myArray = null;

    public function __construct($myArray)
    {
        $this->myArray = $myArray;
    }

    public function getFromArray($name)
    {
        return $this->myArray[$name];
    }

    public function __call($method, $arguments)
    {
        $field = lcfirst(substr($method, 3));

        return $this->getFromArray($field);
    }

    public function __get($name)
    {
        return $this->getFromArray($name);
    }
}

MyThingSpec.php

<?php

namespace spec;

use PhpSpec\ObjectBehavior;

class MyThingSpec extends ObjectBehavior
{
    function let(\ArrayAccess $myArray)
    {
        $this->beConstructedWith($myArray);
    }

    function it_retrieves_my_array_details(\ArrayAccess $myArray)
    {
        $myArray->offsetGet('foo')->shouldBeCalled()->willReturn('bar');

        $this->getFromArray('foo')->shouldReturn('bar');
    }

    function it_retrieves_my_array_details_with_a_magic_call(\ArrayAccess $myArray)
    {
        $myArray->offsetGet('foo')->shouldBeCalled()->willReturn('bar');

        $this->getFoo()->shouldReturn('bar');
    }

    function it_retrieves_my_array_details_by_accessing_a_property(\ArrayAccess $myArray)
    {
        $myArray->offsetGet('foo')->shouldBeCalled()->willReturn('bar');

        $this->foo->shouldReturn('bar');
    }
}

Awesome! I think this should be added to the official documentation somewhere!

The \ArrayAccess can't be used in all situations as described in official documentation.

@martcor in retrospect, I would not mock ArrayAccess nor any native language behaviour. Just create the thing.
