PHPUnit test with Zend Framework 3

Question

I got the error below in PHPUnit Controller test in Zend Framework 3:

Exception 'Zend\\ServiceManager\\Exception\\ServiceNotCreatedException' with message 'Service with name "Zend\\Db\\Adapter\\AdapterInterface" could not be created.

The same tests were working fine in Zend Framework 2. The following method in TestController is causing the issue.

$this->configureServiceManager($this->getApplicationServiceLocator());

is it deprecated?

After 4 days, I was able to figure out the problem and the fix.

 protected function updateConfig($config)
    {
        $config['db'] = [];

  $config['db']['driver'] = 'Pdo'; 

        return $config;
    }

I had to the driver manually to fix the issue, Hope it will help others with the same error.
