Mocking multiple types reports errors with phpstan 0.12

[Khartir]

Calling createMock with multiple Types causes phpstan to report errors:

A class like

<?php declare(strict_types=1);

namespace App;

use PHPUnit\Framework\TestCase;

class Test extends TestCase
{

    public function testDummy(): void {
        $this->createMock([\DateTimeInterface::class, \ArrayAccess::class]);
    }
}

throws the following errors:

 ------ ------------------------------------------------------------------------------------------------------------------------------------------------- 
  Line   Test.php                                                                                                                                         
 ------ ------------------------------------------------------------------------------------------------------------------------------------------------- 
  11     Parameter #1 $originalClassName of method PHPUnit\Framework\TestCase::createMock() expects class-string<mixed>, array<int, class-string> given.  
  11     Unable to resolve the template type T in call to method PHPUnit\Framework\TestCase::createMock()                                         
 ------ ------------------------------------------------------------------------------------------------------------------------------------------------- 

The error also occurs, if there is only one class given, but not as a string, but as an array:
$this->createMock([\DateTimeInterface::class]); produces the same error.

This is working fine in phpstan 0.11

I inspected the code in 0.11 and it couldn't have worked before, you just received MockObject without intersected mocked classes. So 0.12 just surfaces that it doesn't do what you want it to do. Of course it can be fixed with a similar extension I reverted here (in favour of stubs): https://github.com/phpstan/phpstan-phpunit/blob/79d30f7074ecb773c70147a01478b31efca79023/src/Type/PHPUnit/CreateMockDynamicReturnTypeExtension.php
