Setting APP_ENV = testing in phpunit.xml I got errors

Making tests for laravel site I want to use .env.testing file

I managed to make it code in 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"
             printerClass="Sempro\PHPUnitPrettyPrinter\PrettyPrinterForPhpUnit9"
    >
        <testsuites>
            <testsuite name="Pages CRUD tests">
                <directory suffix="Test.php">./tests/Feature</directory>
            </testsuite>
        </testsuites>
        <coverage processUncoveredFiles="true">
            <include>
                <directory suffix=".php">./app</directory>
            </include>
        </coverage>
        <php>
            <env name="APP_ENV" value="testing"/>
            <env name="BCRYPT_ROUNDS" value="4"/>
            <env name="CACHE_DRIVER" value="array"/>
            <env name="TELESCOPE_ENABLED" value="true"/>

            <!--         <env name="DB_CONNECTION" value="sqlite"/>-->
            <!--         <env name="DB_DATABASE" value=":memory:"/>-->
            <env name="MAIL_MAILER" value="array"/>
            <env name="QUEUE_CONNECTION" value="sync"/>
            <env name="SESSION_DRIVER" value="array"/>
            <env name="TELESCOPE_ENABLED" value="false"/>
        </php>
    </phpunit>

clearing cache with command :

    php artisan config:clear

I got errors on test run on any test in my file:

    ERRORS!
    Tests: 12, Assertions: 0, Errors: 12.

But all the rests are running ok I suppose that it is related that that now .env.testing is used, but how can it be fixed?

"phpunit/phpunit": "^9.5.10"
"laravel/framework": "^9.2"

Thanks in advance!
