Problem with Autorouting improved and HTTP Testing

Hi,
I'm new in the forum and I hope this is the right place to request some support for the following issue.
Following the guidelines concerning autorouting improved, I have a controller with two different methods:

PHP Code:

getCreate()
postCreate() 


during testing HTTP Feature if I call

PHP Code:

$result = $this->post('section/create', $dataPost); 


then the Section::getCreate method is called instead of Section::postCreate.

As workaround, I added a route in my test

PHP Code:

$routes = [
            ['post', 'section/create', 'Section::postCreate'],
        ]; 


and the using it, the test works

PHP Code:

$result = $this->withRoutes($routes)->post('section/create', $dataPost); 


Am I doing something wrong? Or there is a problem with autorouting and HTTP Feature test?

Thenk you,
Massimiliano
