There is no mention of actually installing Pest in the testing documentation.

I just did a clean install of Laravel 9 and was running through some of the php artisan make:model commands. I saw there was also a --pest flag to generate an accompanying test for the model.

This is fine and also the docs state you can create tests using Pest:

https://laravel.com/docs/9.x/testing#creating-tests

However nowhere is there any mention that you should install Pest for any of this to work. For PHPUnit is makes perfect sense to omit a composer require because PHPUnit is already part of the require-dev in the composer file.

I think it should be made clear that this is not some out of the box solution and that it needs to be installed explicitly. But even beyond that point I find it pretty fucking strange that we have an option available like a --pest flag which is part of an integral command (namely make:model) which totally breaks down without you manually installing a third party package. This just feels wrong.

Either make it part of the require-dev in the composer.json or don't include these flags at all.
