Boot events break with Event::fake() when testing

[rask]

I'm trying to test event dispatching in my application using the PHPUnit tools provided by Laravel.

In a test where Event::fake() is called before creating a new Model (a User for instance) the package's UUID trait's boot method seems to break.

I get MySQL errors relating to field id not having a default value:

QueryException: SQLSTATE[HY000]: General error: 1364 Field 'id' doesn't have a default value (SQL: insert into ...

I'm using Laravel 5.6 as my application base.

Trimmed example code to reproduce:

<?php

class migration_dis_and_dat
{
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->uuid('id');
            $table->string('email')->unique();
            $table->string('password');
            $table->timestamps();

            $table->primary('id');
        });
    }
}

<?php

class User extends Model {
    use UuidModelTrait;

    ...
}

<?php

class UserTest extends TestCase
{
    public function test_user_create_dispatches_event()
    {
        Event::fake();

        User::create(['email' => 'foo@bar.com', 'password' => Hash::make('helloworld'));

        // around here the error should appear,
        // if you comment `Event::fake()` and `Event::assertDispatched`
        // then the user should be created normally

        Event::assertDispatched(MyEvent::class);
    }
}

Have you tried setting the id by using the Faker library?

[rask]

The ID is not fillable but I think I could try that for the sake of testability of the events themselves.

Also try to report this to laravel/framework project, you may get some feedback whether this is an issue with the framework or if there are any clean solutions to it.
