Run test before deploy

[devskio]

Hello, I want to run some tests before each deployment.
My task config looks as follows:

task('test:php-cs-fix', function () {
    $result = runLocally('./vendor/bin/php-cs-fixer fix --dry-run');
});

fail('test:php-cs-fix', function() {
    if (askConfirmation('Do You want to run PHP CS Fixer now?', true)) {
        runLocally('./vendor/bin/php-cs-fixer fix');
        info('Please check & commit PHP CS Fixes and then you can deploy');
    } else {
        warning('Please run PHP CS Fixer first and then try to deploy again!');
    }
});

task('test', [
    'test:php-cs-fix',
])->desc('Test the project');
before('deploy', 'test');

But when I run dep deploy and tests fails, default deploy fail task is executed and not one I defined.
How can I run my fail function?

Thank you for the help!
