mvlabs/zf2behat-extension

Behat extension for Zend Framework 2 inspired by Symfony2extension by Konstantin Kudryashov.

Behat (http://behat.org/) is a php framework for Behavior Driven Development. This extension allows you to use it in your Zend Framework 2 projects. It initializes Behat, allowing you to quickly use your Gherking features within ZF2.

1.Requirements

This extension is installed through composer and has following dependencies:

"php":">=5.3.3",
"behat/behat":"=2.4@stable",
"zendframework/zendframework":">=2.2.0"

Composer will take care of installing these for you (see below).

2.Installation

In order to install this extension, you only need to add the following in your Zend Framework 2 composer.json:

"require": {
     "mvlabs/zf2behat-extension" : "dev-master"
}

and then run composer.phar install (or update). At this point, you need to create a file named behat.yml in your application root folder with following content:

default:
 extensions:
    MvLabs\Zf2Extension\Zf2Extension:

3.Usage

If you don't have an existing test suite, please proceed to 4.Initialization within a Module. Otherwise, you can use this extension within your existing test suite in 2 different ways:

If you are using php version 5.4+, you can use MvLabs\Zf2BehatExtension\Context\Zf2Dictionary trait which provides basic ZendFramework 2 functionality. This functionality can only be used in one Context though.
You can implement the MvLabs\Zf2BehatExtension\Context\Zf2AwareContextInterface for every context, avoiding to call parent context from subcontexts.

Both methods call a method setZf2App(Application $zf2Application) needed to set in a private property Zend\Mvc\Application to be reused on every step needed

4.Initialization inside a Module

In order to initialize your feature suite inside a Zend Framework 2 module, you need to execute:

$ php bin\behat --init "<module name>"

So, for example, if you want to initialize the skeleton application, you could just do from your application root directory:

vendor/bin/behat --init Application

After the command is executed it will create a Features folder inside your module with a extension ready FeatureContext inside the Context subfolder. You should see following output in console:

+d module/<module name>/src/<module name>/Features - place your *.feature files here
+f module/<module name>/src/<module name>/Features/Context/FeatureContext.php - place your feature related code here

5.Running your features

Now that you have your Features directory within your module source folder (module//src/) you can create your first feature file in Gherkin. Please refer to the official behat documentation (http://docs.behat.org/quick_intro.html#define-your-feature) to see how to create your first feature file.

At this point, you only need to run:

vendor/bin/behat <module_name>

to run the feature against your module.

6.Feature profiles

If you often find yourself running a specific module suite it's possible to set a module parameter inside a profile in your behat.yml file like in the example below:

default:
  extensions:
      MvLabs\Zf2Extension\Zf2Extension:
        module: <module_name>

You can then just call behat without arguments:

vendor/bin/behat

Within a profile you can use a specific Zend Framework config/application.config.php file, through the following:

default:
  extensions:
      MvLabs\Zf2Extension\Zf2Extension:
        module: <module_name>
	config: <my_custom_config_file_path>

7.Multiple feature profiles

You can also use multiple profiles, such in the example below:

default:
  extensions:
      MvLabs\Zf2Extension\Zf2Extension:
        module: User

example:
   extensions:
      MvLabs\Zf2Extension\Zf2Extension:
        module: Albums

After setting those profiles, you can your Albums module suite executing:

$ php bin\behat -p=example

8.Specific Feature Execution

You can run specific features specifying file name:

$ php bin\behat "<module folder/feature folder/feature file>"

9.Appication Level Feature Suite

If you don't want to use module-centric structure it's possible maitain an application structure specifing a features path and context class in your behat.yml file like in the example:

default:
  paths:
    features: features
  context:
      class: ModuleDemo\Features\Context\CustomContext

Using this path you shuold only remember to add your context class in the autoloader.

10.Configuration Parameters

Supported options for profiles are:

module - set the module to be runned for a specific profile (only one module per profile is currently supported)
config - set a custom configuration file. if it is not specified config/application.config.php will be loaded
