You are running an artisan command
test:setup. As far as i know that is not a standard laravel artisan command.
Someone in that project probably made a custom command in the
app/commands folder that installs those packages for you so you are able to run certain custom tests.
If you want to remove it:
Look inside the
app/commands or search your project for a file like
testCommand.php and disable the code.
You can read more about artisan commands in the docs.
