How to Phpunit test a method in an abstract class that uses other methods

Question

I have an abstract class as follows:

abstract class Entity
{

  public function __construct($configFile, $logger, $database)
  {
    $this->configFile = $configFile;
    $this->logger = $logger;
    $this->database = $database;
  }


  public function SettingData(array $info)
  {
        $this->logger->debug('setting the information'.serialize($info));
        $info = $info.'debug';
        $this->formatData();
        return true;
    }
}

Here is the unittest:

  $data = array('informations','data');
  $result = Entity::SettingData($data);
  $this->assertTrue($result);

I want to test the method SettingData but I get the error:

Undefined property: Entity::$logger

How Am I supposed to test this method?

Any help is really apreaciated.

Answer 1

You cannot test an abstract class. You have to create a derived class. Then you create an object of that class and call the constructor with testable parameters. After that you can test SettingData.
