Data provider specified for test is invalid. Unable to locate factory with name [default]

Q	A
PHPUnit version	6.5.8
PHP version	7.2.3
Installation Method	Composer

Some data in dataProvider didn't work:

public static function multilangualGuestProvider()
    {
        return [
            [factory(Guest::class)->create()]
        ];
    }

    /**
     * @param $guests
     *
     * @dataProvider multilangualGuestProvider
     */
    public function testEditValidId($guests)
    {
        $guest = factory(Guest::class)->create();

Output:

1) Warning
The data provider specified for GuestTest::testEditValidId is invalid.
Unable to locate factory with name [default] [App\Models\Guest].

But without using DataProvider (public function testEditValidId()) it works correctly.
