I am using the following code to test interactive console application.

$input_stream = $this->getInputStream("Some user input\n");
$question_helper = new QuestionHelper();
$question_helper->setInputStream($input_stream);

$helper_set = $application->getHelperSet();
$helper_set->set($question_helper);

$tester = new ApplicationTester($application);
$tester->run($arguments);

It works well but it is not compatible with Symfony 4 because setInputStream() method has been removed.

The documentation suggests using StreamableInputInterface::setStream() but I could not find any way to set Input for ApplicationTester.

Any suggestions?
