It seems like you code against a specific sub-type and not the parent class Symfony\Component\Console\Application as the method getContainer() does only exist in the following sub-classes of Symfony\Component\Console\Application: PhpSpec\Console\Application. Maybe you want to instanceof check for one of these explicitly?

It seems like you code against a concrete implementation and not the interface Symfony\Component\Console\Helper\HelperInterface as the method ask() does only exist in the following implementations of said interface: Symfony\Component\Console\Helper\QuestionHelper, Symfony\Component\Console\Helper\SymfonyQuestionHelper.
