The type PHPUnit\Framework\TestCase was not found. Maybe you did not declare it correctly or list all dependencies?

The method getName() does not exist on Behavioral\Observer\SubjectInterface. Since it exists in all sub-types, consider adding an abstract or default implementation to Behavioral\Observer\SubjectInterface.
