Hello @psdevhh .
I reproduced same errors when i had bad configuration of install-config-mysql.php.dist file.
Please check the data of this file and if you don't use Redis please detele this:
'amqp-host' => 'localhost', 'amqp-port' => '5672', 'amqp-user' => 'guest', 'amqp-password' => 'guest',.
I have to close this issue, but i am waiting for your response.
Thanks for your report!

Hi @engcom-Charlie
You're right, turns out I had to specify localhost instead of 127.0.0.1 as mysql host to get the tests working. As usual, the error messages are very helpful in such cases ;) Thanks a lot for your help!
