[TomasVotruba]

Closes #1381

Before

class SomeServiceTest extends \PHPUnit\Framework\TestCase
{
    public function test()
    {
        $this->doTestMultiple([1, 2, 3]);
    }
}

After

class SomeServiceTest extends \PHPUnit\Framework\TestCase
{
    /**
     * @dataProvider provideDataForTest()
     */
    public function test(int $value)
    {
        $this->doTestSingle($value);
    }

    public function provideDataForTest(): Iterator
    {
        yield [1];
        yield [2];
        yield [3];
    }
}
