Apply phpunit.xml setting for speific classes only - laravel

Question

I have the following setting in my phpunit.xml:
<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="./vendor/phpunit/phpunit/phpunit.xsd"
bootstrap="vendor/autoload.php"
colors="true">
<testsuites>
<testsuite name="Application Test Suite">
<directory suffix="Test.php">./tests</directory>
</testsuite>
</testsuites>
<coverage processUncoveredFiles="true">
<include>
<directory suffix=".php">./app</directory>
</include>
</coverage>
<php>
<env name="APP_ENV" value="testing"/>
<env name="CACHE_DRIVER" value="array"/>
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
</php>
</phpunit>
How can i tell to phpunit to use :memory: for certain test class and not for all classes ?

Unfortunately, PHPUnit is now unable to use custom environments for only some test suites. So you can't use the following code:
...
<testsuite name="Application Test Suite">
<directory suffix="Test.php">./tests</directory>
<php>
<env name="DB_DATABASE" value="example_db"/>
</php>
</testsuite>
...
So instead of setting the env DB_DATABASE via the phpunit.xml file, you can set it via the new .env file. Suppose you create a .env.first file that contains:
DB_DATABASE=first_db
Then in the phpunit.xml file, you can create a new <testsuite> which you will later target to use with the .env file you have created. As an example:
<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="./vendor/phpunit/phpunit/phpunit.xsd"
bootstrap="vendor/autoload.php"
colors="true">
<testsuites>
<testsuite name="Foo">
<directory prefix="FirstDB" suffix="Test.php">./tests</directory> <!-- Will match all files in `./tests` whose filename contains a FirstDB prefix and a Test.php suffix -->
</testsuite>
<testsuite name="Bar">
<directory prefix="SecondDB" suffix="Test.php">./tests</directory>
</testsuite>
</testsuites>
<coverage processUncoveredFiles="true">
<include>
<directory suffix=".php">./app</directory>
</include>
</coverage>
<php>
<env name="APP_ENV" value="testing"/>
<env name="CACHE_DRIVER" value="array"/>
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value="second_db"/>
</php>
</phpunit>
Then for the next step you can run it with:
php artisan test --env=first --testsuite=Foo
php artisan test --testsuite=Bar
