This extension changes PhpSpec's IdentityMatcher from "===" to PHPUnit's assertEquals() method. Also it changes PhpSpec's differ to PHPUnit's one.

Motivation

1. PHPUnit has time proven comparation library than does more than just "==" or "===", so that we can simply use it and do not worry about using "shouldBeLike()" instead of "shouldReturn()".

1. Differ.

For example we have classes:

class Value
{
    private $value;

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

class TestValueObject
{
    public function getValue($value)
    {
        return new Value($value + 1);
    }
}

class TestValueObjectSpec extends ObjectBehavior
{
    function it_can_get_value()
    {
        $this->getValue(42)->shouldReturn(new \Value(42));
    }
}

PhpSpec output without this extension ("shouldReturn" was changed to "shouldBeLike")

$ bin/phpspec run spec/TestValueObjectSpec.php -v
TestValueObject
  10  ✘ it can get value
      expected [obj:Value], but got [obj:Value].

        10     function it_can_get_value()
        11     {
        12         $this->getValue(42)->shouldBeLike(new \Value(42));
        13     }
        14 }
