Cannot return objects in @dataProvider PHPUnit

Question

Is it allowed to return objects from @dataProviders to test methods?

public function iOsMessages()
{
    return [
        'update available'        => [1, new UpToDateMessage(), 'pl'],
    ];
}

/**
 * @test
 * @dataProvider iOsMessages
 */
public function success_create_message_for_ios(int $appVersion, MobileMessage $message, string $locale)
{
(...)

Error:

The data provider specified for Tests\Tests\Mobile\Classes\AppVersionTest::success_create_message_for_ios is invalid. Class 'Mobile\Classes\Messages\UpToDateMessage' not found

MobileMessage is an interface, imports are correct.

The error message says the class doesn't exist. PHPUnit is not guilty for that. Check the configuration of the autoloader and/or the class name and namespace. — axiac, Feb 05 '18 at 15:24
Just remember that the data providers are executed only once before all the tests from a test case. — axiac, Feb 05 '18 at 15:25
@axiac Does it make any difference? Those providers are used only once in separate tests. — wujt, Feb 05 '18 at 15:33

From the documentation:

A data provider method must be public and either return an array of arrays or an object that implements the Iterator interface and yields an array for each iteration step.
