Mink+Behat: missing session - behat

Question

I was just trying to follow the http://docs.behat.org/cookbook/behat_and_mink.html tutorial
I installed Mink+Behat using the following composer.json:
"require": {
"behat/behat": "2.4.*#stable",
"behat/mink": "1.4.*#stable",
"behat/mink-extension": "*",
"behat/mink-goutte-driver": "*",
"behat/mink-selenium2-driver": "*"
},
"minimum-stability": "dev",
"config": {
"bin-dir": "bin/"
}
}
I did the init that created the features directory.
bin/behat --init
I created a search.features in the features directory:
Feature: Search
In order to see a word definition
As a website user
I need to be able to search for a word
Scenario: Searching for a page that does exist
Given I am on "/wiki/Main_Page"
When I fill in "search" with "Behavior Driven Development"
And I press "searchButton"
Then I should see "agile software development"
Scenario: Searching for a page that does NOT exist
Given I am on "/wiki/Main_Page"
When I fill in "search" with "Glory Driven Development"
And I press "searchButton"
Then I should see "Search results"
I updated the features/bootstrap/FeatureContext.php to extend MinkContext.
If i run bin/behat -dl i see the following definitions loaded:
Given /^(?:|I )am on (?:|the )homepage$/
When /^(?:|I )go to (?:|the )homepage$/
Given /^(?:|I )am on "(?P<page>[^"]+)"$/

Then /^(?:|I )should see (?P<num>\d+) "(?P<element>[^"]*)" elements?$/
Then /^print current URL$/
Then /^print last response$/
Then /^show last response$/
But I try to actually test the search.features , i get the error:
PHP Fatal error: Call to a member function getSession() on a non-object in /home/nishant/behat/vendor/behat/mink-extension/src/Behat/MinkExtension/Context/RawMinkContext.php on line 103
I did a Google of what the error could be, but didnot find anything more useful that telling to put the behat.yml in the right place.
My bin/behat -> ../vendor/behat/behat/bin/behat is this symlink and i have tried putting behat.yml in vendor/behat/behat/behat.yml. content on behat.yml
default:
extensions:
Behat\MinkExtension\Extension:
base_url: http://en.wikipedia.org
goutte: ~
selenium2: ~
Any help would be much appreciated!!
If I go to vendor/behat/behat and create the search.feature and run bin/behat I get the error:
[ReflectionException]
Class Guzzle\Http\Client does not exist

Answer 1

Ok.. i managed to fix my problem !
Added these lines in my __construct() method in features/bootstrap/FeatureContext.php
$clientOptions = array();
$client = new \Behat\Mink\Driver\Goutte\Client();
$client->setClient(new \Guzzle\Http\Client('', $clientOptions));
$driver = new \Behat\Mink\Driver\GoutteDriver($client);
Also updated my composer.json to
{
"require": {
"behat/behat": "2.4.*#stable",
"behat/mink": "1.4.*#stable",
"behat/mink-extension": "*",
"behat/mink-goutte-driver": "1.0.*",
"behat/mink-selenium2-driver": "*",
"guzzle/http": "*"
},
"minimum-stability": "dev",
"config": {
"bin-dir": "bin/"
}
}
