Why does not find the required class in phpunit?

Question

PHP

Good afternoon!
I'm setting up PHPUnit for the first time and I ran into such a problem, unit tests inherited from the PHPUnit_Framework_TestCase class work fine, but for some needs I still needed to connect more listeners components via PHPUnit_Framework_BaseTestListener and tests to the database via PHPUnit_Extensions_Database_TestCase . And phpunit does not see them.
Details:
phpunit.xml

<?xml version="1.0" encoding="UTF-8" ?>
<phpunit
        bootstrap="./vendor/autoload.php"
        colors="true"
        convertErrorsToExceptions="true"
        convertNoticesToExceptions="true"
        convertWarningsToExceptions="true"
        processIsolation="false"
        stopOnFailure="false"
        syntaxCheck="false">
   <listeners>
        <listener class="DBInit" file="./tests/listeners/DBInit.php">
        </listener>
    </listeners>
    <testsuites>
        <testsuite name="Main PHPUnit Tests">
            <directory>./tests/</directory>            
        </testsuite>
    </testsuites>
    <php>
        <var name="DB_HOST" value="localhost" />
        <var name="DB_USER" value="root" />
        <var name="DB_PASSWORD" value="" />
        <var name="DB_DBNAME" value="ural_catalog_tests" />
        <var name="VERSION" value="1.0" />
    </php>
</phpunit>

Can you suggest why it does not see these classes. Maybe I made a mistake somewhere in the test settings?
PS The php version I am using is 5.6
