Page Object Extension with Behat 3 and Mink 1.5 throws an Exception

Question

I've a project running with Behat 2.4, Mink 1.4 and Behat Page Object Extension, with this version my tests is fine, 100% passed.

But now i'm migrating to Behat 3 due to the fully integration with Browserstack, Behat 2 doesn't support BrowserStack flags and the integration is poor.

I've changed my composer file and I updated project, but when I run the tests, it is returning an Exception on Page Object Extension.

To create pages you need to pass a factory with setPageObjectFactory() (RuntimeException)

Looking at Page Object Docs I don't see anything about setPageObjectFatory, this isn't needed. In configuration section, only specifies factory if you create a custom factory or/and custom class name resolver.

My composer with all dependencies is

{
    "require-dev" : {
        "behat/behat" : "master-dev",
        "behat/mink-goutte-driver" : "master-dev",
        "behat/mink-browserkit-driver" : "master-dev",
        "sensiolabs/behat-page-object-extension" : "master-dev",
        "behat/mink-extension" : "master-dev",
        "behat/mink-selenium2-driver" : "master-dev",
        "behat/mink" : "master-dev"
    }
}

And my behat.yml bellow

default:
  suites:
    default:
      contexts:
        - FeatureContext
        - ProductDetailsContext
        - CartContext
      extensions:
        SensioLabs\Behat\PageObjectExtension:
          namespaces:
            page: [Features\Page]
            element: [Features\Page\Element]
        Behat\MinkExtension:
          sessions:
            my_session:
              browser_stack:
                username: my_username
                access_key: my_password
                capabilities: 
                  browserName: "Chrome"
                  browserVersion: "35"
                  platform: "WIN8"

My FeatureContext extending MinkContext

<?php

use Behat\MinkExtension\Context\MinkContext;

/**
 * Behat context class.
 */
class FeatureContext extends MinkContext
{
}

And ProductDetailsContext extending PageObjectContext

<?php
use SensioLabs\Behat\PageObjectExtension\Context\PageObjectContext;

/**
 *
 *
 */
class ProductDetailsContext extends PageObjectContext
{
    /**
     * @Given /^I am on product details "([^"]*)"$/
     *
     * @param string $url
     */
    public function iAmOnProductDetails($url)
    {
        $this->getPage("ProductDetails")->open(array("productUrl" => $url));
    }

    /**
     * @Given /^I am at a random product details$/
     */
    public function iAmAtARandomProductDetails()
    {
        $catalog = $this->getPage("Catalog");
        $catalog->open(array('category' => 'calcados-femininos'));
        $catalog->openRandomProduct();
    }

    /**
     * @When /^I select product size$/
     */
    public function iSelectProductSize()
    {
        $this->getPage("ProductDetails")->selectProductSize();
    }

    /**
     * @Then /^I add product to cart$/
     */
    public function iAddProductToCart() {
        $this->getPage("ProductDetails")->addProductToCart();
    }

    /**
     * @Then /^I add product to wishlist$/
     */
    public function iAddProductToWishlist()
    {
        $this->getPage("ProductDetails")->addProductToWishlist();
    }
}

I don't know how can solve this and I need help.

Answer 1

The problem is because Extensions was configured inside of suites, put the Extensions outside suites and it works.

default:
  suites:
    default:
      contexts:
        - FeatureContext
        - ProductDetailsContext
        - CartContext
  extensions:
    SensioLabs\Behat\PageObjectExtension:
      namespaces:
        page: [Features\Page]
        element: [Features\Page\Element]
      Behat\MinkExtension:
        sessions:
          my_session:
            browser_stack:
              username: my_username
              access_key: my_password
              capabilities: 
                browserName: "Chrome"
                browserVersion: "35"
                platform: "WIN8"

Answer 2

This is a long shot, but here we go… In previous Behat version you've used single / root context, which must have extended PageObjectContext. It must have been the only / first context that was initialised, it was also the right context to initialise page factory and the pages themselves. Now you have multiple contexts, the logical step would be to ensure that they all implement SensioLabs\Behat\PageObjectExtension\Context\PageObjectAwareInterface as said in the docs here.

I also don't see 'SensioLabs\Behat\PageObjectExtension' entry under extensions. I don't think Behat would initialise the extension without it being on the list (it can't just randomly guess that it must be loaded, right?). This is probably the first thing you should change. Based on the docs about configuration and given you followed the default convention, everything should work.

Answer 3

Try to install

composer require --dev --ignore-platform-reqs sensiolabs/behat-page-object-extension:^2.0

In the composer I've add --ignore-platform-reqs because i'm use php 7.* for my works
