How to test Doctrine Custom Types

Question

As described here it is possible to create custom Types.

I've done it, but now I'd like to test the class but unfortunately this is not possible.

Infact, a custom type extends the class Doctrine\DBAL\Types\Type that seems that cannot be instantiated.

Infact, its constructor is built this way:

/**
 * Prevents instantiation and forces use of the factory method.
 */
final private function __construct()
{
}

As told in the comment, it is required the use of the factory method to instantiate the class, but, what this factory method is? Where can I find it?

you could take a look at the DBAL test suite, as example see this test https://github.com/doctrine/dbal/blob/master/tests/Doctrine/Tests/DBAL/Types/DecimalTest.php — Matteo, Oct 06 '16 at 15:51
Mmm... It seems `Doctrine\Tests\DBAL\Mocks\MockPlatform;` is unfoundable! -.-' — Aerendir, Oct 06 '16 at 18:46
They mention this [here](https://github.com/ramsey/uuid/issues/16#issuecomment-24575462) but I'm not sure how they broke it. — mickadoo, Oct 12 '16 at 10:12

Through a combination of not replacing any methods in a mock and some tips from an issue on github I was able to make a unit test for a doctrine type. I guess this works for simpler types where the platform isn't relevant. For more complex type behavior you could substitute the platform with a different mock.

/**
 * @test
 */
public function willCastValueToInt()
{
    $typeBuilder = $this
        ->getMockBuilder(IntegerType::class)
        ->disableOriginalConstructor()
        ->setMethods(null);

    $type = $typeBuilder->getMock();
    $platform = $this->getMockForAbstractClass(AbstractPlatform::class);

    $result = $type->convertToPHPValue('3', $platform);

    $this->assertSame(3, $result);
}
