Bug? Mail::assertQueued working for one test but not another

[garrettboone]

Hi, posting here rather than reporting a bug.

I have two tests that mail out (not notifiy) messages to users.

In one test, Mail::assertQueued($mailable) is showing as true (this is expected).

In a second test, Mail::assertQueued($mailable_2) is showing as false (this is not expected).

In the second test I can see that it is, in fact, queued with dd($this->manager). I set $this->manager = Mail::fake() at setup of the test. The results of dd show:

Illuminate\Support\Testing\Fakes\MailFake^ {#5424
  +manager: Illuminate\Mail\MailManager^ {#4855
    #app: Illuminate\Foundation\Application^ {#4653 …44}
    #mailers: []
    #customCreators: []
  }
  #currentMailer: null
  #mailables: []
  #queuedMailables: array:1 [
    0 => App\Mail\SendResetPasswordLink^ {#5741
      +locale: null
      +from: []
      +to: array:1 [
        0 => array:2 [
          "name" => null
          "address" => "fakeemailhere"
        ]
      ]

It is showing the mailable in the queuedMailables. Even when I run Mail::assertQueuedCount(1); the test passes.

But, Mail::assertQueued(SendPasswordResetLink::class); does not pass:

  FAILED  Tests\Application\Users\UsersTests > an admin user can create a user
  The expected [App\Mail\SendPasswordResetLink] mailable was not queued.
Failed asserting that false is true.

The two mailables are identical in structure and differ only in mail content.

Why does this happen?

Additionally:
dd(Mail::queued(SendPasswordResetLink::class)->count()); produces 0.
dd(Maill:hasQueued(SendPasswordResetLink::class)); is false.
Mail::assertOutgoingCount(1); passes.

And, drumroll...
Mail::assertNothingQueued(); fails.

It seems to be coming down to that the $mailable is not an instanceof $type here

framework/src/Illuminate/Support/Testing/Fakes/MailFake.php

Line 408 in ebd115f

return (new Collection($this->queuedMailables))->filter(fn ($mailable) => $mailable instanceof $type);

When I dump the new Collection($this->queuedMailables) from each test, they look the same to me other than they are a different Mailable class.

Illuminate\Support\Collection^ {#5433
  #items: array:1 [
    0 => App\Mail\SendResetPasswordLink^ {#5741
      +locale: null
      +from: []
      +to: array:1 [
        0 => array:2 [
          "name" => null

Illuminate\Support\Collection^ {#3595
  #items: array:2 [
    0 => App\Mail\FormSubmissionConfirmation^ {#3554
      +locale: null
      +from: []
      +to: array:1 [
        0 => array:2 [
          "name" => null

The second one shown had two emails go out in the test.

Never mind! Typo.
