Behat in TYPO3

typo3_behat.md

We have an extension PROJECT_NAME-testing, which holds a composer.json like this:

{
    "name": "punktde/PROJECT_NAME-testing",
    "description" : "punkt.de testing suite for PROJECT_NAME",
    "license": "proprietary",
    "repositories": [
        {
            "type": "git",
            "url": "git@gitlab.pluspunkthosting.de:pt/punktde-testing.git"
        }
    ],
    "autoload": {
       "psr-4": {
           "TYPO3\\Flow\\": "vendor/punktde/testing/Classes/PunktDe/Testing"
       }
    },
    "require": {
        "punktde/testing": "dev-master"
    },
    "scripts": {
        "post-update-cmd": "PunktDe\\Testing\\Composer\\InstallerScripts::postUpdateAndInstall",
        "post-install-cmd": "PunktDe\\Testing\\Composer\\InstallerScripts::postUpdateAndInstall"
    },
    "config": {
        "bin-dir": "bin"
    }
}

Inside a generic composer package punktde/testing, we have another composer.json which looks like this:

{
    "name": "punktde/testing",
    "type": "typo3-flow-package",
    "description": "punkt.de Testing",
    "license": "LGPL-3.0+",
    "require": {
        "phpunit/dbunit": ">=1.2",
		"mikey179/vfsStream": "~1",
        "behat/behat": "3.0.11",
        "behat/mink-extension": "2.0.0",
        "behat/mink-selenium2-driver": "*",
        "guzzle/guzzle": "3.9.2"
    },
	"config": {
		"bin-dir": "bin/"
	},
    "autoload": {
        "psr-0": {
            "PunktDe\\Testing": "Classes"
        }
    }
}

that's where Behat is loaded into our extension directory structure. Finally, we get the following directory structure inside the project-specific testing extension:

.
├── Fixtures
├── Tests
│   ├── Behat
│   ├── Functional
│   └── Selenium
├── behat.yml
├── bin
│   ├── phpunit -> ../vendor/phpunit/phpunit/phpunit
│   └── behat -> ../vendor/bin/behat
├── composer.json
├── composer.lock
├── ext_emconf.php
├── ext_icon.gif
├── ext_localconf.php
├── ext_tables.php
└── vendor
    ├── autoload.php
    ├── behat
    ├── bin
    ├── composer
    ├── doctrine
    ├── guzzle
    ├── instaclick
    ├── mikey179
    ├── phpunit
    ├── punktde
    ├── sebastian
    └── symfony

We can now run Behat from within this extension with bin/behat PARAMETERS

Since TYPO3 7 I think you can use composer from the root of your TYPO3 installation - so I would rather put the whole Behat stuff outside any extension and into a testing directory on the same level as your htdocs folder.

Hope, this helps...
