That's strange, I don't get this problem.
Are you using PHPUnit or Pest ?
Is it perhaps a typo problem ?
--parrallel has to be written with only one r => --parallel.

Cannot run --parallel tests
hello! i'm trying to run my integration and unit tests in parallel, i have followed the official guide and installed paratest as a dev dependency. But when i try to run them with the --parallel parameter i get
NunoMaduro\Collision\Adapters\Laravel\Exceptions\RequirementsException
Running Collision 8.x artisan test command in parallel requires at least ParaTest (brianium/paratest) 7.x.
I tried searching online and i don't understand why i get this. i'm running laravel 12 on php 8.4 and phpunit.

If you downgrade, perhaps it's worth reloading all vendor dependencies.
