Laravel 9 command serve does not use custom .env file

[fbsanchez]

• Laravel Version: 9.0.1
• PHP Version: 8.0.15
• Database Driver & Version: php-mysqlnd-8.0.15-1.fc35 connected to mysql:8 (docker) / sqlite3

Description:

command php artisan serve --env=testing seems not to be working since it is still using default .env file instead.

Steps To Reproduce:

With mysql running using default .env file (configured against mysql)

With mysql stopped using custom .env.testing file (configured against sqlite)

With mysql stopped moving .env.testing to .env file

Another easy test is not having a .env file at all and specify custom one:

This time results into a err 500

local.ERROR: No application encryption key has been specified. {"exception":"[object] (Illuminate\\Encryption\\MissingAppKeyException(code: 0): No application encryption key has been specified. at /tmp/laravel-serve-bug/vendor/laravel/framework/src/Illuminate/Encryption/EncryptionServiceProvider.php:79)

Thanks

Thought this issue affects https://github.com/laravel/laravel instead but I didn't see how to report it 😅

@ugorur seems like your PR broke this? #37142. Can you confirm you added a bad negation there?

I actually can't recreate the issue. Does your .env.testing file actually contain APP_ENV=testing. If not - add it - that solves the root issue for me.

Hello @taylorotwell by adding APP_ENV=testing instead local this seems to be working fine

Thank you!
