Change test case methods to snake_case and mention Pest support

[JohnnyWalkerDigital]

Update naming convention to match official Laravel documentation. (These "best practices" are currently out-of-step with modern Laravel standards.)

Reasoning:

• Laravel officially changed to snake_case for test case methods in version 8.0.
• Current Laravel documentation uses snake_case.
• All Laracast videos use snake_case.
• The previous discussion's reasoning to use camelCase for test case methods is no longer valid (aside from it not being PSR-12).

@alexeymezenin You seem to be engaging with this repo again... How about bringing it up to speed with current Laravel standards?

Snake case should be used in tests regardless Laravel.

It differs from regular methods and force developer to pay extreme attention to those.
It differs from regular (app) methods that should be written following PSR standards.
Personally, I comply/obey 100% PSR standards which means I use camelCase for methods, but for testing methods I use snake_case.

@alexeymezenin Are you ever going to address this issue? I want to use this repo as a reference, but I can't while it's outdated.

@JohnnyWalkerDigital Hi. I believe this was discussed before, I also remember mentioning huge discussion on this topic which took place many years ago. Long story short, there is no reason to use snake case just for PHPUnit tests just because some people got used to it.

Laravel is following PSR coding standards and snake case clearly violates those https://laravel.com/docs/11.x/contributions#coding-style

@alexeymezenin I have linked to the previous discussion and mentioned the problems with that discussion already. I have included official Laravel documentation demonstrating that the Laravel project uses snake_case in Test methods names. I have even linked to the actual PR request when that decision was codified (4 years ago).

@driesvints "We decided a while back to go for snake case as our convention for methods names in tests."

Even typing php artisan make:test AnotherExampleTest creates a class with the example method: public function test_example(): void

It's sad that these so-called "best practices" are now years behind actual real-world Laravel conventions.
