Can't use `Str::createUuidsUsing()` with `Notification::fake()`

[Livijn]

I use this to get a deterministic value in my test but I get an exception: Str::createUuidsUsing(fn () => 'some-uuid');

Error: Call to a member function toString() on string in /Users/fredrik/Documents/code/getapet-backend/vendor/laravel/framework/src/Illuminate/Support/Testing/Fakes/NotificationFake.php:317

This is caused by using ->toString(). What we could instead do is to use $notification->id = (string) Str::uuid();.

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

Line 317 in 95fc3d0

$notification->id = Str::uuid()->toString();

but I get an exception: Str::createUuidsUsing(fn () => 'some-uuid');

To use the toString method, you need to return a Stringlable|UuidInterface. Your callback is returning exactly string, so it throws an exception.

[hctorres02]

Instead of:

Str::createUuidsUsing(fn () => 'some-uuid');

Use:

Str::createUuidsUsing(fn () => \Ramsey\Uuid\Uuid::fromString('some-uuid'));

Or if you don't want to use the Ramsey\Uuid\Uuid class, you can build your own generator, but this might be a lot of work.

I put up a PR for this. Most of the places in the framework just use (string) Str::uuid() but there were a few that do not, such as the one you identified.

In the interim, I think you could use this instead:

Str::createUuidsUsing(function () {
    return new class {
        public function __toString() {
            return 'uuid';
        }
    };
});
