I installed Symfony 3 with the command line as they show in their documentation, and installed PHPUnit.
phpunit --version
PHPUnit 6.0.6 by Sebastian Bergmann and contributors.
When I run phpunit in the command line, I get this error:
PHP Fatal error: Class 'PHPUnit_Framework_TestCase' not found in D:\symfony\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\Test\KernelTestCase.php on line 23
Thanks in advance for any help
