Laravel Notification asserting the data passed down to mail markdown view - laravel

Question

I am working on a Laravel project. I am writing integration/ feature tests for my application. I am now writing a test where I need to assert the data passed to the email notification and the data passed to its view. I found this link to do it, https://medium.com/#vivekdhumal/how-to-test-mail-notifications-in-laravel-345528917494.
This is my notification class
class NotifyAdminForHelpCenterCreated extends Notification
{
use Queueable;
private $helpCenter;
public function __construct(HelpCenter $helpCenter)
{
$this->helpCenter = $helpCenter;
}
public function via($notifiable)
{
return ['mail'];
}
public function toMail($notifiable)
{
return (new MailMessage())
->subject("Help Center registration")
->markdown('mail.admin.helpcenter.created-admin', [
'helpCenter' => $this->helpCenter,
'user' => $notifiable
]);
}
}
As you can see in the code, I am passing data to mail.admin.helpcenter.created-admin blade view.
This is my test method.
/** #test */
public function myTest()
{
$body = $this->requestBody();
$this->actingAsSuperAdmin()
->post(route('admin.help-center.store'), $body)
->assertRedirect();
$admin = User::where('email', $body['admin_email'])->first();
$helpCenter = HelpCenter::first();
Notification::assertSentTo(
$admin,
NotifyAdminForHelpCenterCreated::class,
function ($notification, $channels) use ($admin, $helpCenter) {
$mailData = $notification->toMail($admin)->toArray();
//here I can do some assertions with the $mailData
return true;
}
);
}
As you can see my comment in the test, I can do some assertions with the $mailData variable. But that does not include the data passed to the view. How can I assert or get the data or variables passed to the blade view/ template?

Answer 1

As you can see here, there is a viewData property on the MailMessage class which contains all the data passed to the view, no need to turn the notification into an array.
$notification->toMail($admin)->viewData
So it would be something like this in your case:
/** #test */
public function myTest()
{
$body = $this->requestBody();
$this->actingAsSuperAdmin()
->post(route('admin.help-center.store'), $body)
->assertRedirect();
$admin = User::where('email', $body['admin_email'])->first();
$helpCenter = HelpCenter::first();
Notification::assertSentTo(
$admin,
NotifyAdminForHelpCenterCreated::class,
function ($notification, $channels) use ($admin, $helpCenter) {
$viewData = $notification->toMail($admin)->viewData;
return $admin->is($viewData['user']) && $helpCenter->is($viewData['helpCenter']);
}
);
}
