class HelloController extends Controller
{

    public function indexAction()
    {

      return $this->redirect($this->generateUrl('homepage'));
    }
}

2. Typing php app/console services:list from the command line.

3. There is no clear way to know them.

21.- How can you return a 404 error from a Controller?

1. throw $this->createNotFoundException("Page not found");

2. throw new NotFoundHttpException("Page not found");

3. return $this->createNotFoundException("Page not found");

4. return new NotFoundHttpException("Page not found");

5. 404 errors are not coded, they are triggered only when a route is not matched

22.- How can you return a 500 error from a Controller?

1. $response = new Response(); $response->setStatusCode(500); return $response;

2. return new \Exception('Something went wrong!');

3. throw new \Exception('Something went wrong!');

4. You cannot force a 500 Error, they just happen.

23.- How can Twig error pages be customized?

1. Working with the kernel.exception Event. HttpKernel catches the kernel.exception event you can work with.

2. Error pages take the base.html.twig and extend it by default

3. Create a template in app/Resources/TwigBundle/views/error.html.twig. You can be more error specific, for example app/Resources/TwigBundle/views/error500.html.twig.

4. Overriding the Default Exception Controller, in congif.yml setting this key for the twig configuration: exception_controller: AppBundle:Exception:showException

24.- What's up with this code?

$request->getSession()->getFlashBag()->add(
    'terrible_notice',
    'You ran out of milk!'
);

1. You can get this value in a twig template with app.session.flashbag.get('terrible_notice')

2. It will return an exception. Only 'notice', 'error', 'info' and 'warning' are valid for flash messages categories

3. It will be available for the next view render and disappear in the next one

4. You can read this message as long as the current user session exists

25.- What's true about this code?

$response = new Response(json_encode(array('name' => $name)));
$response->headers->set('Content-Type', 'application/json');

1. Setting the content type header is redundant. The headers are correctly set when creating the Response object at first line

2. Response http status code will be 200

3. Response http status code will be null

4. application/json is not a valid Content-Type

26.- How can you determine a request is an Ajax request?

1. Reading the "X-Requested-With" header. In Symfony with $request->headers->get('X-Requested-With');

2. There is no way to know it. They are not different to any other http request.

3. In Symfony, with $request->isXMLHttpRequest();

4. Reading the "X-Requested-With" header. In Symfony, with $request->request->get('X-Requested-With');

27.- How can you access to a request from a controller that extends de Controller Symfony class

1. $this->get('request')

2. $this->containter->get('request')

3. $this->getRequest();

4. Request::createFromGlobals()

28.- How can you know the accepted languages a browser accpets in a request?

1. $request->getPreferredLanguage()

2. $request->headers->all()['accept-language']

3. $request->getLanguages()

4. $request->headers->get('Accept-Language')

5. There is no way to know it

29.- Can you render a template without writing a custom controller?

1. Yes, specifying it in the routing file. Example with keys: _controller: FrameworkBundle:Template:template, template: static/privacy.html.twig

2. No, that breaks MVC. Symfony does not allow it.

3. Yes, from another template. For example, in Twig {{ render(url('acme_privacy')) }}

4. No, if you want to do it, you must set rewrite rules in .htaccess

30.- What does this code on execution in a Controller?

public function indexAction($name)
{
    $response = $this->forward('AppBundle:Something:fancy', array(
        'name'  => $name,
        'color' => 'green',
));
    // ... further modify the response or return it directly
    return $response;
}

1. It will render a template called fancy and variables 'name' and 'color' will be available

2. It will execute "public funcion fancy()" in the "class Something" in the Controller namespace.

3. It will look for the route named fancy and will pass 'name' and 'green' parameters

4. It will perform a 302 redirect

5. None of the above are correct

31.- You have a Controller defined as service this way. What would you do to render a template?

# app/config/services.yml
services:
    app.hello_controller:
        class: AppBundle\Controller\HelloController

1. Nothing special. I can use the shortcut return $this->render('AppBundle:Hello:index.html.twig')

2. I must use $this->container->get('templating')->renderResponse('AppBundle:Hello:index.html.twig')

3. The container may not be available, I must inject the templating service as parameter in services.yml and in the construnctor in the controller class

4. It is not possible to use a controller as a service. It breaks the MVC

32.- What's true about this route?

// ...

/**
 * @Route("/blog/{slug}", name="blog_show")
 */
public function showAction($slug)
{
   // ...
}

1. It will match /blog

2. It will match /blog/my-first-post

3. It will match /blog_show/my-first-post

4. As it is an annotation, it depends on SensioFrameworkExtraBundle

33.- Routing file is found in app/config/routing.yml when you install the Standard Edition. Can you change it afterwards?

1. Yes, changing the app/confing.yml entry: router: { resource: "%kernel.root_dir%/config/routing.yml" }

2. No, it is one of the hardcoded parts of Symfony Framework

34.- Given this route and controller definition, what's true about them?

/**
 * @Route("/blog/{page}", defaults={"page" = 1})
 */
public function indexAction($page = 2)
{

     */
    public function indexAction($page)
    {
      // ...
    }
    /**
     * @Route("/blog/{slug}")
     */
    public function showAction($slug)
    {
     // ..
    }
}

1. If the request is /blog, it will match the first route

2. If the request is /blog/my-first-post, it will match the first route

3. If the request is /blog/my-first-post, it will match the second route

4. If the request is /blog/my-first-post, and exception will be thrown

5. There will be a exception, routes have no names

36.- Given this route and controller definitions are the only ones in the application, what's true about them?

// src/AppBundle/Controller/MainController.php
// ...
class MainController extends Controller
{
    /**
     * @Route("/{_locale}", defaults={"_locale": "en"}, requirements={
     *     "_locale": "en|fr"
     * })
     */
    public function homepageAction($_locale)
    {
    }
}

1. If the request is /es, $_locale will be null

2. If the request is /es, Error 404 will happen

3. If the request is /tren, $_locale = en

4. If the request is /tren, $_locale = tren

5. None of the above are correct

37.- What's the way to import a external routing file?

1. It is not possible. All routing definitions must be in a single file.

2. Adding a resource key this way: resource: "@AcmeOtherBundle/Resources/config/routing.yml"

3. Adding a import key: import: "@AcmeOtherBundle/Resources/config/routing.yml"

4. Adding a resource key this way: resource: "../Resources/config/routing.yml"

38.- Given this route and controller definition, what's true about them?

// src/AppBundle/Controller/MainController.php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
// ...

{
    /**
     * @Route("/news")
     * @Method("GET")
     */
    public function newsGetAction()
    {
        // ... display your news
}
    /**
     * @Route("/news")
     * @Method({"POST"})
     */
     public function newsPostAction()
     {
         // ... display and process a contact form
     }
}

1. Any request to /news with any parameters and method will always fall in the first controller, newsGetAction()

2. A POST request to /news will return a 404 error always

3. A request to /news with no extra parameters will fall in the first controller, newsGetAction()

4. A PUT request to /news will return a 404 error

39.- Given this routing configuration, which of the answers are true?

homepage:
    path:     /

            {% block body %}{% endblock %}
        

    


Template 2 -

{# src/AppBundle/Resources/views/blog/index.html.twig #}
{% extends 'AppBundle::base.html.twig' %}
{% block title %}My cool blog posts | {{ parent() }}{% endblock %}

1. Twig Runtime Error, parent() cannot be used as filter

2. A page with just this content: <title>My cool blog posts | Test Application </title>

3. A page with title '<title>My cool blog posts | Test Application </title>' and all other elements of base.html.twig

4. Twig Runtime Error, parent() is a function, should be invoked this way: {% parent() %}

54.- Consider these two Twig templates, what would be the output of index.html.twig render for AppBundle?


Template 1 -

{# src/AppBundle/Resources/views/base.html.twig #}


    
        
        {% block title %}Test Application{% endblock %}
    
    
        
            {% block sidebar %}
                
                    Home

                    Blog

                

            {% endblock %}
        

        
            {% block body %}{% endblock %}
        

    


Template 2 -

{# src/AppBundle/Resources/views/blog/index.html.twig #}
{% extends '@AppBundle/base.html.twig' %}
{% block title %}My cool blog posts{% endblock %}

1. The notation {% extends '@AppBundle/base.html.twig' %} is not valid, it will render just the 'My cool blog posts' string

2. It will render Temaplate 1 contents, changing the title tag to 'My cool blog posts'

3. A Twig Runtime Error. Template not found

4. Empty page

55.- You have these two Twig templates, what $this->render('AppBundle::index.html.twig') will render?

Template 1 -

{# app/Resources/AppBundle/views/index.html.twig #}


    
        
        {% block title %}Test Application{% endblock %}
    
    
        
            {% block body %} Hello! 
{% endblock %}
        

    


Template 2 -

{# src/AppBundle/Resources/views/index.html.twig #}


    
        
        {% block title %}Test Application{% endblock %}
    
    
        
            {% block body %} Hello! 
{% endblock %}

1. The template containing <h1> Hello! </h1>

2. The template containing <h2> Hello! </h2>

3. A Twig Runtime Error. Template not found

4. Empty page

56.- You have these two Twig templates, what $this->render('AppBundle::index.json.twig') will render?


{# src/AppBundle/Resources/views/index.html.json #}


    
        
        {% block title %}Test Application{% endblock %}
    
    
        
            {% block body %} Hello! 
{% endblock %}

1. Will render the template setting the Content-Type header to text/html

2. Will render the template setting the Content-Type header to application/json

3. A Twig Runtime Error. Json parse error

4. Empty page

57.- Whats the correct syntax for the include helper?

1. With {{ include('AppBundle::article/article_details.html.twig' }} from Symfony 2.3 onwards

2. With {% include('AppBundle::article/article_details.html.twig' %}

3. Include helper is not available in Twig, you should use template inheritance

4. With {{ include('AppBundle:includes:article_details:html.twig' }}

58.- Considering you have these two Twig templates. Would this work?

Template 1 -

{# app/Resources/views/article/list.html.twig #}
{% extends 'layout.html.twig' %}
{% block body %}
    Recent Articles

    {% for article in articles %}
        {{ include('article/article_details.html.twig') }}
    {% endfor %}
{% endblock %}

Template 2 -

{# app/Resources/views/article/article_details.html.twig #}
{{ article.title }}


 by {{ article.authorName }}


    {{ article.body }}

1. No, you need to pass the article variable to the included template this way {{ include('article/article_details.html.twig', { 'article': article }) }}

2. Yes, the article variable is available form the parent template

59.- Would you consider rendering a template calling a controller from a Twig template?

1. No, it cannot be done. You can only include other templates.

2. Yes, using the Twig render function this way {{ render(controller('AppBundle:Article:recentArticles', {'max':3} )) }}

3. Yes, it is useful when you need to add complex logic not availalble in Twig

4. Yes, but you can only call controllers defined as services

60.- Symfony supports asyncronous content includes with hinclude.js. What's true about it?

1. You can include controllers or templates with {{ render_hinclude(controller('...')) }} or {{ render_hinclude(url('...')) }}

2. If using from controllers, you must enable the Symfony fragments configuration

3. You can render content from another domain with {{ render_hinclude(url('http://www.otherdomain.com/xxxx')) }}

4. You can render a default template until the desired one is loaded or if the user does not support javascript with {{ render_hinclude(controller('...'), {'default': 'default/content.html.twig' }) }}

61.- What's Assetic intended for?

1. Json files

2. CSS files

3. Javascript files

4. Image files

62.- Consider this Twig template piece. Assuming Assetic is correctly installed, what sentences are true?

{% block stylesheets %}
    {% stylesheets '@FOSCommentBundle/Resources/assets/css/comments.css'
                    '/media/css/all.css'
                    '/custom/css/*'%}
    
    {% endstylesheets %}
{% endblock %}

1. The output will be a unique css file with the path like /css/abc123456.css

2. It will add any file in the directory /custom/css/*

3. If there are relative paths, they will be broken since the 'cssrewrite' filter is not used

4. You must must run php assets:intall command at some point before if you want to get the FOSCommentBundle assets displayed

63.- What's the purpose of the {{ asset() }} function

1. It's a synomym of path function

2. It identifies the correct path of an asset

3. If asset_version is enabled, it appends the versioning parameter to the asset. It doesn't otherwise.

4. The assets in it are minimized by default

64.- Consider this assetic configuration

# app/config/config.yml
assetic:
    filters:
        coffee:
            bin:        /usr/bin/coffee
            node:       /usr/bin/node
            node_paths: [/usr/lib/node_modules/]
            apply_to:   "\.coffee$"

1. It will apply this filter to any file ending in .coffee passed through assetic

2. It will apply this filter if you add filter='coffee' when rendering the asset

3. It won't apply this filter if you don't add filter='coffee' when rendering the asset

4. None of the above are true

65.- Which template variables are global and accesible from any Twig template?

1. The concept of global variable does not exist in Twig

2. app.security, app.user, app.controller, app.session and app.kernel are the only ones

3. app.security, app.user, app.controller, app.request and app.kernel are the only ones

4. app.security, app.user, app.session, app.request, app.environment and app.debug are the only ones

66.- Consider this configuration. Which of the answers are true?

# app/config/config.yml
framework:
    # ...
    templating:
        engines: ['twig', 'php']

1. Adding php engine is not necessary, it is enabled by default

2. You can set the template engine to use with the annotation @Template(engine="php") in the controller action

3. Just rendering AppBundle:Hello:index.html.php will set the engine to php

4. If you try to render AppBundle:Hello:index.html.blade will result in a Runtime Error

67.- Given this Twig code, if an user sets his name to <script>alert('hello!')</script>, what will the output be?


Hello {{ name }}

1. Hello <script>alert('hello!')</script>

2. Hello <script>alert('hello!')</script> if I set the | raw filter

3. Hello

4. Hello <script>alert('hello!')</script>, html output escaping is enabled by default

68.- In what way can you access the 'data-foo' array index for the array foo in Twig?

1. foo['data-foo']

2. foo.data-foo

3. foo.['data-foo']

4. attribute(foo, 'data-foo')

69.- What's the order of all steps accessing a variable property "bar" in Twig when doing foo.bar?

1. array index "bar", object property "bar", object method "bar()", object method getBar(), object method isBar()

2. object method getBar(), object property "bar", array index "bar", array index "bar"

3. array index "bar", object method getBar()

4. Just checks for array index "bar"

70.- Consider this twig configuration. Which of the answers are true?

# Twig Configuration
twig:
    strict_variables: "%kernel.debug%"

1. In debug mode, rendering non exisiting variables will show a null value

2. In debug mode, "%kernel.debug%" value is 1

3. In debug mode, rendering non exisiting variables will throw an error

4. In non debug mode, rendering non existing variables will throw an error

71.- What's true about this Twig code?

{# app/Resources/views/article/recent_list.html.twig #}
{{ dump(articles) }}
{% for article in articles %}
    
        {{ article.title }}
    
{% endfor %}

1. Variable articles will be dumped in all enviroments

2. Dump function does not exist. You must use other ways to debug, like the profiler

3. The contents of the dump will be logged to app/log/<environment>.log and will be not displayed

4. Variable artiches will be dumped only if debug mode is enabled

72.- What will be the output of the command php app/console twig:lint app/Resources/views

1. File not found

2. twig:lint command does not exists in Symfony Standard Edition

3. It will iterate and parse all templates in app/Resources/views and check for Twig syntax errors

4. It will correct the formatting to PSR-2

73.- Consider this Twig Extension configuration setup, how can invoke it?


//src/AppBundle/Twig/SayYeahExtension.php
namespace AppBundle\Twig;

class SayYeahExtension extends \Twig_Extension
{

    public function getFilters()
    {
        return array(
            new \Twig_SimpleFilter('say_yeah', array($this, 'sayIt'))
        );
    }

    public function sayIt($text)
    {
        return $text." Yeah!";
    }

    public function getName()
    {
        return "sayYeah";
    }
}


\# app/config/services.yml
services:
    say_whatever.gromenaguer:
        class: AppBundle\Twig\SayYeahExtension
        public: false
        tags:
            - { name: twig.extension }

1. {{ text | sayYeah }}

2. {{ text | say_yeah }}

3. {{ text | say_whatever }}

75.- How can I know the available bundles int the current Symfony installation

1. Checking the method registerBundles() in app/AppKernel.php

2. Checking contents of app/config/services.yml

3. Runnig the command php app/console config:dump-reference. It will also show the bundle aliases.

4. Running the command php app/console container:debug

76.- What diferenciates each enviroment in Symfony?

1. They must have different kernels

2. They must have different front controllers

3. They must have different routes

4. They should have different configurations, although they can have the same.

77.- At which point is the Symfony configuration loaded?

1. Each service is responsible for finding and loading its configuration files

2. The configuration loading is not handled within Symfony Framework

3. In the AppKernel, with registerContainerConfiguration() method

4. In each Bundle, in their declaration class

78.- What is true about a Symfony Bundle?

1. A bundle is simply a structured set of files within a directory that implement a single feature

2. Everything is a bundle in Symfony

3. Core Symfony bundles are loaded by default, they don't need to be defined in the AppKernel's registerBundles() method

4. It must have a set of directories or it will fail to be loaded

79.- If a Bundle lives in src/Acme/AwesomeBundle/, what should be the main class name following the naming convention?

1. Controller, DependencyInjection, Tests

2. Listeners, Utils, Twig

3. web, vendor, app

4. Resources/config/, Resources/views, Resources/public

82.- Does the php app/console generate:bundle register a bundle in your Symfony app?

1. No, it must be done manually.

2. It asks for it. If agreed, it is added in the registerBundles() AppKernel's method automatically

83.- What's the directory by default for your functional and unit tests?

1. app/Tests

2. Tests in the Root directory of the Symfony installation

3. Tests directory in each bundle

1. Tests/phpunit.yml

2. app/confing/phpunit.yml

3. app/config/phpunit.xml.dist

4. app/phpunit.xml.dist

85.- Consider this Unit Test. Would it work?

//src/AppBundle/Tests/Utils/SyllableSeparatorTest.php
namespace AppBundle\Tests\Utils;

use AppBundle\Utils\SyllableSeparator;

class SyllableSeparatorTest {

    public function testTildes() {

        $tests = array ('bíceps' => 1,
            'imágen' => 0,
            'ataúd' => 1,
            'estáis' => 1);

        $i = 0;
        foreach ($tests as $word => $result) {

            $analyzer = new SyllableSeparator($word);

            $this->assertEquals($result, $analyzer->llevaTilde());

            $analyzer = null;
            $i++;
        }
    }
}

1. No, the methods should be named *Test, in this case tildesTest()

2. No, the class SyllableSeparatorTest should be located in another directory

3. No, the method testTildes() should return something, we need to add return $this->assertEquals($result, $analyzer->llevaTilde());

4. No, the class should extend \PHPUnit_Framework_TestCase

5. Yes, there is no problem with it.

86.- What should be the default directory for a functional test?

1. Tests/Functional

2. src/<bundle>/Tests/Functional

3. src/<bundle>/Tests/Controller

4. src/<bundle>/Resources/Tests/Functional

87.- Consider this Functional Test. Would it work?

//src/AppBundle/Tests/Utils/SyllableSeparatorTest.php
namespace AppBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DefaultControllerTest extends WebTestCase
{
    public function testIndex()
    {
        $client = static::createClient();

        $crawler = $client->request('GET', '/');

        $this->assertEquals(200, $client->getResponse()->getStatusCode());
        $this->assertContains('Lleva tilde esta palabra', $crawler->filter('div.container h1')->text());
    }
}

1. No, the methods should be named *Test, in this case indexTest()

2. No, the class SyllableSeparatorTest should be located in another directory

3. No, the method testIndex() cannot have two assertions;

4. No, the class should extend \PHPUnit_Framework_TestCase instead of WebTestCase

5. Yes, there is no problem with it.

88.- Does a Functional Test bootstrap the kernel of your application

1. No, it is an external test to the application.

2. Yes, as it handles a request

3. Yes, but you must set the kernel in the phpunit configuration file

4. Yes, but if you use a custom kernel, you must set it in the configuration file

89.- What's the output of this code?


$client = static::createClient();

1. $client is a Client() object

2. $client is a Crawler() object

3. $client is a string containing the UserAgent

4. $client is null

90.- What's the output of this code?


$client = static::createClient();
$crawler = $client->request('GET', '/post/hello-world');

1. $crawler is a Client() object

2. Regular expressions

3. Array keys

4. XPath selector with the fitlerXPath() method

93.- What's the result of this piece of code?


$link = $crawler->filter('a:contains("Greet")');

1. An array of Crawler objects

2. A Crawler object

3. A String

4. A Client object

94.- What's the result of this piece of code?


$this->assertContains(
   'Hello World',
   $client->getResponse()->getContent()
 );

1. It will work, since $client->getResponse()->getContent() returns a string

2. It will work, since $client->getResponse()->getContent() returns a Crawler object

3. The method assertContains() method does not exist

4. It won't work, since $client->getResponse()->getContent() returns a Response object

95.- Can you access the container form a Functional test class?

1. No, a Functional test is designed to block that access

2. Yes, from a client object, $client->getContainer()

96.- What's the output of this Crawler method?


$crawler->attr('class');

1. Selects all times with the attribute class and returns a Crawler object

2. Selects all times with the attribute class and returns an array

3. Gets the content of the attribute class of the first node

4. It won't work, you should specify the node index: $crawler->eq(1)->attr('class');

97.- What's the output of this Crawler method?


$info = $crawler->extract(array('_text', 'href'));

1. $info will contain an array with all node texts and node attributes href of the Crawler instance

2. $info will contain an array with all node texts and node attributes href of the first node

3. $info will select all tags named _text and href

4. It will throw an error, extract only accepts one parameter.

98.- What's the output of this Crawler code snippet?


$data = $crawler->each(function ($node, $i) {
    return $node->attr('href');
});

1. $data will contain a crawler object with all links of the Crawler instance

2. $data will contain an array with all links of the Crawler instance

3. $data will contain a string with the last link

4. $data will be empty in any case

99.- What's wrong with this code?

$link = $crawler->selectLink('Click here');
$client->click($link);

1. It will select any clickable image with the alt text "Click Here", but the click won't work.

2. It will select any link with the text "Click Here", but the click won't work.

3. It will work if we add $crawler->selectLink('Click here')->link(), so we create a link object we pass to the click method

4. Nothing, it will work

100.- Consider this Crawler code, which of the sentences are true?

$buttonCrawlerNode = $crawler->selectButton('submit');

$form = $buttonCrawlerNode->form(array(
          'name' => 'Frank',
          ), POST);

$client->submit($form, array(
    'name' => 'Peter'
      ));

1. You can only override form fields in the form method

2. You can only override form fields in the submit method

3. Both are valid ways to override default values of the form. It will submit a POST with the field name = 'Peter'

4. Both are valid ways to override default values of the form. It will submit a POST with the field name = 'Frank'
