Asserting Action message contents fails

[Jigsaw5279]

When asserting that an action responds with a specific message, the test case fails with the following error

Failed asserting that Laravel\Nova\Actions\ActionResponse Object #1410 (
    'danger' => null
    'deleted' => null
    'download' => null
    'message' => 'Registrierung bestätigt'
    'name' => null
    'openInNewTab' => null
    'redirect' => null
    'visit' => null
    'modal' => null
    'data' => Array &0 ()
) is of type array and matches the "message" Action response.

Here's the excerpt from the test case

self::novaAction(QuickConfirmAction::class)
            ->handle([], $registration)
            ->assertMessage('Registrierung bestätigt');

I'm having the same issue. As a workaround for now I'm using:

$response = $action->handle([], [$model]);
$response->assertMessageContains('my message here');

I think PR #59 is related to this
