[Bug]: extend(RefreshDatabase::class) refreshes local database

What Happened

When i use pest()->extend(Tests\TestCaseUnit::class)->in('Unit'); in my Pest.php when i run my tests it refreshes my database that i have configured in .env, even when my test database i have theses environment variables inside my phpunit.xml

<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>

How to Reproduce

On a Laravel application using Pest, add the following to your Pest.php

pest()->extend(Tests\TestCaseUnit::class)->extend(RefreshDatabase::class);

Set the values in phpunit.xml

<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>

or .env.testing should have

DB_CONNECTION=sqlite
DB_DATABASE=:memory:

Then when running tests, it should refresh the database used in your .env

Notes

No response

Start with the Pest.php extension using Tests\TestCaseUnit and RefreshDatabase, then inspect how environment values from phpunit.xml or .env.testing are applied during the test run. Reproduce with SQLite :memory: settings and verify that RefreshDatabase does not refresh the database configured in .env.
