不能在@dataProvider PHPUnit 中 return 个对象

Question

是否允许 return 来自 @dataProviders 的对象测试方法？

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)
{
(...)

错误：

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是一个接口，导入是正确的。

Answer 1

来自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.
