Behat appends additional url when redirecting - symfony

Question

I'm using Symfony 3.4 with FOSUserBundle and Behat for testing.
Config & code:
Behat config:
extensions:
Behat\MinkExtension:
sessions:
default:
symfony2: ~
javascript:
selenium2: ~
browser_name: firefox
show_auto: false
base_url: 'http://my-virutalhost.test'
Behat\Symfony2Extension:
kernel:
env: "acceptance"
debug: "true"
Scenario: I execute enpoint address with wrong redirect code
When I go to the url "/redirect/code1code2"
Then I should be redirected to url "http://some-page-here.com"
/**
* #When /^I go to the url "([^"]+)"$/
*/
public function iGoToTheUrl($url) {
$this->lastResponse = $this->getSession()->visit($url);
$this->getSession()->getDriver()->getContent();
//var_dump($url, $this->getSession()->getDriver()->getCurrentUrl());
}
/**
* Checks, that current page PATH matches regular expression.
*
* #Then /^(?:|I )should be redirected to (?P<pattern>"(?:[^"]|\\")*")$/
*/
public function iAmRedirectedToUrl($pattern) {
$this->assertSession()->addressMatches($this->fixStepArgument($pattern));
}
Problem:
Somehow Behat appends to my redirect url http://some-page-here.com /login from my app, which creates link: http://some-page-here.com/login. I don't know why it creates such address for redirect.
-- EDIT --
When I check the content of page $this->getSession()->getDriver()->getContent() I see code of the login page
-- Edit --
/login - it's my application login
I want to make redirect to
outside page, not in a page inside of my application and check if the final address is the address of the page from outside redirect
My security config:
access_control:
- { path: ^/redirect, role: IS_AUTHENTICATED_ANONYMOUSLY }

Answer 1

I would look closer at Firefox, because I don't think Behat is the culprit here.
From what I can make out, what is happening is:
Behat tells Firefox to navigate to 'http://my-virutalhost.test/redirect/code1code2'
This URL responds with a HTTP redirect to 'http://some-page-here.com/'
Firefox honours the HTTP redirect but for some reason appends /login to the URL.
I would look into the responses that Firefox is getting to ensure that the correct redirect url is returned.

Is your redirect ok ? If your content page show the /login, then When I go to the url "/redirect/code1code2" must send to this page.
As you use the MinkExtension, did you tried with the default Step When I go to '/redirect/code1code2' ?
Or have you access to the page if you do directly When I go to the url 'http://some-page-here.com' ?
And for the http://some-page-here.com/login stuff, It's strange... If your page is able to show you the /login content, then it must say it has access to http://my-virutalhost.test/login
