Behat无法初始化：Client :: createResponse（）的声明应该与createResponse（）兼容

Question

I am trying to set-up Behat but it fails to init when I run bin/behat --init. My composer.json is taken from the official docs:

{
    "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/"
    }
}

The composer install works fine and looks like all dependencies get installed.

# behat.yml
default:
  paths:
    features:  features
    bootstrap: features/bootstrap

  extensions:
    Behat\MinkExtension\Extension:
      base_url: http://en.wikipedia.org
      goutte: ~
      selenium2: ~

annotations:
  paths:
    features: features/annotations

closures:
  paths:
    features: features/closures 

Running # bin/behat --init yields the following error:

PHP Strict Standards:  Declaration of Behat\Mink\Driver\Goutte\Client::createResponse() should be compatible with Goutte\Client::createResponse(GuzzleHttp\Message\Response $response) in /web/Test-1/vendor/behat/mink-goutte-driver/src/Behat/Mink/Driver/Goutte/Client.php on line 23

  [ReflectionException]
  Class Guzzle\Http\Client does not exist

Could somebody tell me why? I did everything exactly like in official article.

Answer 1

You are using incompatible versions of Mink extensions / drivers. The following pulls the latest versions compatible (right now) with Behat 3 and Mink 1.6, while you want to use much older versions (2.4.* and 1.4.* respectively).

"behat/mink-extension": "*",
"behat/mink-goutte-driver": "*",
"behat/mink-selenium2-driver": "*"

I am assuming you've pulled this from the Internet, as I can't find a different example out there with fixed versions, which is pretty ironic, as the same people are probably blogging at the same time about how much of a bad practice that is. If you are just beginning, I suggest you stick with the latest versions of Behat and Mink, they are much better and have been more than stable for the past 6 months. Change you composer.json and update the dependencies:

"behat/behat": "*",
"behat/mink": "*"

If not, go to each extension / driver repo and find the tagged version from early-mid 2013, that should fix it for the older packages.

Update

The code you provided doesn't work because you are using the old config format with the new Behat / Mink version. Don't forget, Behat 2 configs must be upgraded for Behat 3. Documentation is still pretty poor, but the basics are covered rather well here and here. Updating your config to this resolves the issue:

default:
  extensions:
    Behat\MinkExtension:
      base_url: http://en.wikipedia.org
      goutte: ~
      selenium2: ~

  suites:
    default:
      paths: 
        - '%paths.base%/features'

    annotations:
      paths:
        - '%paths.base%/features/annotations'

    closures:
      paths:
        - '%paths.base%/features/closures'

Here are the the packed files, just in case you get lost, the init command produces this:

Ian-Bytcheks-MacBook-Pro:behat ianbytchek$ php ./vendor/bin/behat --init
+d features - place your *.feature files here
+d features/bootstrap - place your context classes here
+f features/bootstrap/FeatureContext.php - place your definitions, transformations and hooks here
+d features/annotations - place your *.feature files here
+d features/closures - place your *.feature files here

Update

The root of all evil was the curl module, that was not installed in the author's environment. Instead of a proper warning php tried to mitigate the problem by using an alternative, which didn't help much.
