I'm having problems with the testsuite and it seems that it fails for the latest changes, too.
Actually there seems to be several problems.

• make:migration possibly related to doctrine/migrations-bundle update make:migration runs indefinitely #643 make:migration command is not in agreement with doctrine/migrations:"^3.0" #642
• make:auth, make:entity, make:subscriber and make:form are aborting the make command when there is input.
  This only seems to occur on PHP 7.3 in Travis and locally also on my PHP 7.4.7
  https://travis-ci.org/github/symfony/maker-bundle/jobs/704032589

I've encountered the "Aborted." errors in my tests for make:dto and was able to avoid them when using setArgumentsString().

This fails:

        yield 'dto_no_mutator' => [MakerTestDetails::createTest(
            $this->getMakerInstance(MakeDto::class),
            [
                'TaskData',
                'Task',
                // Mutable public (for simplicity)
                2,
                // Add no mutator to Entity
                'no',
            ])
            ->addExtraDependencies('doctrine')
            ->addExtraDependencies('validator')
            ->setFixtureFilesPath(__DIR__.'/../fixtures/MakeDtoNoMutator')
            ->assert(function (string $output) {
                $this->assertContains('created: src/Dto/TaskData.php', $output);
                $this->assertContains('updated: src/Dto/TaskData.php', $output);
            }),
        ];

while this succeeds:

        yield 'dto_no_mutator' => [MakerTestDetails::createTest(
            $this->getMakerInstance(MakeDto::class),
            [
-               'TaskData',
-               'Task',
                // Mutable public (for simplicity)
                2,
                // Add no mutator to Entity
                'no',
            ])
+           ->setArgumentsString('TaskData Task')
            ->addExtraDependencies('doctrine')
            ->addExtraDependencies('validator')
            ->setFixtureFilesPath(__DIR__.'/../fixtures/MakeDtoNoMutator')
            ->assert(function (string $output) {
                $this->assertContains('created: src/Dto/TaskData.php', $output);
                $this->assertContains('updated: src/Dto/TaskData.php', $output);
            }),
        ];

I think this is related to command arguments being added outside of configureCommand (#626), but could not completely track it down.
Maybe it's also related to #633 and #629

I'm having another bug in the test above, the 'no' input for the ChoiceQuestion always comes out as a boolean.
It's passed correctly in MakerTestEnvironment::runMaker().
