certificationy / symfony-pack Goto Github PK

• Removed all questions that can have differents answers in Symfony2/Symfony3
• Add specific questions about Symfony3 (including new components)

Are you sure for this one ?

Event dispatching seems not be deactivable:
https://github.com/symfony/symfony/blob/4d21ab4e7bbc1578c7f23b65f56fa605aff4fb10/src/Symfony/Component/Console/Application.php#L916
In the code above, there is no condition checking if events are disabled.

Right answer yml is {value: "use myapp\utils\\bar", correct: true} , and it is displayed as use myapptils\bar. The question is from PHP section.

Question : True or false ? path() Twig function generates absolute urls.

According to source, RoutingExtension::path() generates not urls, but paths, and those are absolute by default, but can be made relative by setting the third parameter true. Signature of the helper is:
path($name, $parameters = array(), $relative = false)

Hi,
About the question in php.yml line 44 :
question: 'Does PHP support function overloading?'
answers:
- {value: "Yes, in all cases", correct: false}
- {value: "Yes, but not in all cases", correct: true}
- {value: "Yes, but it depends on the function scope", correct: false}
- {value: "Yes, except when it is an anonymous function", correct: false}

Does the correct answer would be clearer like this?

It could be useful to have basic knowledges about already validated PSR.

AFAIK, Symfony follows all validated PSRS and the PSR 11 (that will be accepted or is accepted?)
http://www.php-fig.org/psr/

ping @scaule if you want to contribute ? :)

Hi,

Thanks for this amazing project :)

Did you plan to release a new version of this package? Currently certificationy-cli is based on version 1.6.1 but this version dates from 2018 and there is newer commits since this release.

Symfony 3 has been released 😃 and a new certification has been announced.

Is there a plan to provide the sf3 questions?

Maybe we start adding a info for which version the pack/files/questions are related.

Why TRACE and OPTIONS methods specified as safe (whereas it is not: https://datatracker.ietf.org/doc/html/rfc2616#section-9.1.1)?

question: 'Which design pattern implements the EventDispatcher component?'
answers:
- {value: Adapter, correct: false}
- {value: Decorator, correct: false}
- {value: Observer, correct: true}
- {value: Mediator, correct: true}

https://symfony.com/doc/current/components/event_dispatcher.html

While running default command php php certificationy.php got yaml parsing errors/warning

During the few weeks of usage I have noticed that some questions and answers could be improved.
I obviously appreciate the effort of having this in general and would like to thank the authors for their efforts - it is a great help indeed.

I wonder whether we should just submit PRs for either grammar / typos / validity of some questions?
I guess it's a massive topic to discuss so I would like to know your opinions first.

Example 1:

Symfony pack - Twig - In twig, what do you use if you want to optimize the size of the generated HTML content? This question IS NOT multiple choice.
  [0] spaceless
  [1] operators
  [2] gzip

The correct answer (in my opinion) is "spaceless" even though the accepted answer is "gzip".
Twig doesn't have any capabilities to gzip the output... it's down to the framework underneath or the web-server returning the response.

Example 2:

Question #4 [Automated tests] What command used for run all of your application tests by default? 
This question IS NOT multiple choice.

  [0] phpunit
  [1] phpunit -c app/
  [2] phpunit -c
  [3] phpunit app/

As per: https://symfony.com/doc/current/testing.html the answer should be probably
./vendor/bin/simple-phpunit
but all the existing answers depend on how phpunit was installed as well as where the phpunit.xml file is located... (I think?)

Example 3: (from PHP pack though)

uestion #8 [Basics] Which of the following are valid PHP variables? 
This question IS multiple choice.

  [0] $0x0
  [1] ${0x0}
  [2] &$variable
  [3] @$foo

Even though ${0x0} is not considered a valid PHP variable - it actually works in all version of PHP from 4.x to 7.2 as long as one refers to it using the ${0x0} notation. so the correct answers should be ${0x0} and @$foo instead of @$foo and &$variable - which causes an error.

Example 4:

Question #6 [HTTP Cache] Which HTTP headers belongs to validation cache model? 
This question IS multiple choice.
  [0] ETag
  [1] Cache-Control
  [2] Cookie
  [3] Expires
  [4] Last-Modified

Accepted answers are: ETag, Last-Modified
I'm not sure what the "validation cache model" is - but if it is a method of controlling browser caching - then Cache-Control and Expires should probably be there as well. If it means "methods of validating the cache" then Expires is a probable candidate. Again - I might be wrong on this - but it's very "tricky" question...
Think 4 is enough to get your opinion on things.

First of all, thanks for this wonderful resource!
I am currently learning also using this book: https://leanpub.com/symfony-selfstudy
There are some questions and topics in there, that are not covered by this pack.

Because of all the copyright stuff and other unclear things i want to know:
How to to add more questions to this pack?

Simply copying from the book might be not a good idea :)
