{
$this->beConstructedWith($inputValue);
$this->__toString()->shouldReturn($expectedValue);
}
public function positiveConversionExamples()

array(1.1, '1.1'),
array(new \DateTime, '\DateTime'),
array(array('foo', 'bar'), 'Array(2)')

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

{
$type = gettype($this->value);
switch ($type) {
case 'array':
return sprintf('Array(%d)', count($this->value));
case 'object':
return sprintf("\\%s", get_class($this->value));
default:
return (string) $this->value;
}
