This is called "Change the message or make it green".
$> vim spec/Bossa/Bundle/TrainingBundle/Controller/CoursesController.php $> bin/phpspec run $> vim src/Bossa/Bundle/TrainingBundle/Controller/CoursesController.php $> bin/phpspec run We add final 3rd example to the controller specification. Which describes how we bring the data into the view.
$> vim spec/Bossa/Bundle/TrainingBundle/Controller/CoursesController.php $> bin/phpspec run $> vim src/Bossa/Bundle/TrainingBundle/Controller/CoursesController.php On this stage, we're describing what we're basically expecting from our controller - to render some view template with specific values. And making this example green.

It's time to introduce our first spec. We install phpspec and tell it we want to describe our controller. PHPSpec will create the controller specification and it will generates the required code for us. We will then just add the relevant behaviour we are expecting and make it green.'
$> vim src/Bossa/Bundle/TrainingBundle/Features/Context/StudentContext.php $> vim app/config/routing.yml In implementing the visiting pages step we recommend that you take advantage of expressive route names. That forces us to add the route in the configuration. Because no class is required, no specs are written. Making sure you visit the url and that the route exists is not enough though. You need to know that the status returned is 200. Which takes us to implementing the controller that will handle that route.
$> vim src/Bossa/Bundle/TrainingBundle/Features/Context/StudentContext.php $> vim src/Bossa/Bundle/TrainingBundle/Features/Context/FeatureContext.php We implement `there are no courses scheduled` step definition. But, as we know that application state is clean at the beginning of each scenario, we're just removing `PendingException` from step definition, marking it as passed. Still in this case, we need to make sure, that we have clean application state before each scenario, so we're adding `@BeforeScenario` hook to purge database with `doctrine/data-fixtures` package.
$> bin/behat --append-snippets $> vim src/Bossa/Bundle/TrainingBundle/Features/Context/FeatureContext.php $> vim src/Bossa/Bundle/TrainingBundle/Features/Context/StudentContext.php By running --append-snippets behat will generate the code you need inside your feature context. It's good practice to keep the default FeatureContext slim and extract a context per roles in the system. The reason is again communication. The steps are read in the first person pointing to that role. The context should not extend BaseMink context. It should rather implement MinkAwareInterface, so you will be able to use mink directly inside your step definitions.

Next, we're configuring our `behat.yml` and updating app/autoload.php to support in-Behat initialization. Then, we generate feature suite for our bundle.
$> vim src/Bossa/Bundle/TrainingBundle/Features/admissions/student_enrols_on_a_course.feature We are adding just enough scenarios to go over the steps of full stack bdd with Symfony. Please note that the order of the scenarios is important. They should ease the conversation. They should be fluid, meaning current scenario should expand the knowledge of previous one and prepare the conversation for the next one. They should be focused on the domain. They should focus on value and provide the "what do we mean" for the feature narrative.
$> app/console generate:bundle -n --namespace Bossa/Bundle/TrainingBundle --dir src $> mkdir -p src/Bossa/Bundle/TrainingBundle/Features/admissions $> vim src/Bossa/Bundle/TrainingBundle/Features/admissions/student_enrols_on_a_course.feature We don't need Behat for starting the conversation. We can jump into describing the features. Features folder go under the root of the bundle. Inside the Features folder we create as many folders as features we will have. The will group the .feature files that contain the different user stories and scenarios for that feature.
$> composer create-project symfony/framework-standard-edition fullstack-bdd-uk12 2.1.1 $> cd fullstack-bdd-uk12 $> vim composer.json $> composer install --dev First stage of project development - bootstraping. On this stage, we're creating Symfony2 Standard Edition project and declaring some dependencies that we will need to use during development: * doctrine/data-fixtures - to use purger, that will clean database for us * behat/behat - to describe business requirements for the project * behat/mink-extension - to test business requirements through web UI * behat/mink-browserkit-driver - to use Symfony2 driver in Mink * behat/symfony2-extension - to integrate Behat with Symfony2 * phpspec/phpspec2 - to describe code-level specifications
