Using Phpunit/ Why phpunit removes all data in my database - laravel

Question

I'm trying to test my functions but everytime I try to run phpunit, it will delete all the records in my tables. I already setup my phpunit.xml file, to just in my test database, I just followed everything in the docs, do I have to setup a sqlite inmy machine, since I don't have that ? or what ? I only have laragon installed and phpmyadmin.
phpunit.xml file
<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"
bootstrap="vendor/autoload.php"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
processIsolation="false"
stopOnFailure="false">
<testsuites>
<testsuite name="Feature">
<directory suffix="Test.php">./tests/Feature</directory>
</testsuite>
<testsuite name="Unit">
<directory suffix="Test.php">./tests/Unit</directory>
</testsuite>
</testsuites>
<filter>
<whitelist processUncoveredFilesFromWhitelist="true">
<directory suffix=".php">./app</directory>
</whitelist>
</filter>
<php>
<env name="APP_ENV" value="testing"/>
<env name="CACHE_DRIVER" value="array"/>
<env name="SESSION_DRIVER" value="array"/>
<env name="QUEUE_DRIVER" value="sync"/>
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
</php>
</phpunit>

Be sure to use the DatabaseMigrations trait in your test classes. Eg.
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\RefreshDatabase;
class SomeTest extends TestCase
{
use DatabaseMigrations;
use RegreshDatabase;
/**
* A basic test example.
*
* #return void
*/
public function testSomething()
{
//some code
}
}
This migrates your data on setup, and then registers a direction to roll back the migrations when the application is torn down at the end of the test.
