PHPUnit gets “ErrorException: Illegal string offset 'address' ” when testnig Maillable hasFrom(…) method

• Laravel Version: 5.6
• PHP Version: 7.1
• Database Driver & Version: Mysql 5.7

Description:

Here's my Mailable class:

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class OrderConfirmation extends Mailable
{
    use Queueable, SerializesModels;

    public $message;
    public $subject;
    public $from;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($message, $subject, $from)
    {
        $this->message = $message;
        $this->subject = $subject;
        $this->from = $from;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->from($this->from)
            ->subject($this->subject)
            ->view('emails.orders.confirmation');
    }
}

I'm trying to check that mail has certain From address like this:

Mail::fake();
$customer = 'test@test.com';
$from = 'from@test.com';
Mail::to($customer)->queue(new OrderConfirmation('Some Message', 'Some Subject', $from));

Mail::assertQueued(OrderConfirmation::class, function ($mail) {
     return $mail->hasFrom('from@test.com');
});

but it gets "ErrorException: Illegal string offset 'address' "

/var/www/vendor/laravel/framework/src/Illuminate/Mail/Mailable.php:597

@timkolm How did you manage to fix this? Struggling with the same.

IIRC the problem was in the fact that I redeclared the properties $message, $subject, $from. You should not use them for they are already declared.
