How to resolve "class not found" in PHPUnit tests? - phpunit

Question

I have just resolved some PHPUnit problems by upgrading to the last version (6.2.1) but and I'm now able to run my tests.
However I have a new error that I can't resolve:
1) BackBundle\Tests\Service\LdapServiceTest::testgetLdapConnect
Error: Class 'BackBundle\Service\LdapService' not found
There is my classTest:
<?php
namespace BackBundle\Tests\Service;
use PHPUnit\Framework\TestCase;
use BackBundle\Service\LdapService;
use PHPUnit_Framework_MockObject_InvocationMocker;
class LdapServiceTest extends TestCase {
public function testgetLdapConnect()
{
$ldap = new LdapService('10.0.0.100','10.0.0.100','mike','password',389,3,false,false);
$ldapMock = $this->getMockBuilder( 'LdapService')->setMethods(array('getldapBind'))->disableOriginalConstructor()->getMock();
$ldapMock->expects($this->any())
->method('getLdapBind')
->with(array('ldap_bind', 'mike', 'password'))
->will($this->returnValue(true));
$this->assertTrue($ldap->getLdapBind());
// $LdapService = new LdapService();
// $LdapService.getLdapBind();
// $ldapMock->isAuthorized('mike', 'password');
}
}
And here is my phpunit.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.de/manual/current/en/appendixes.configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
