Behat 3.0.8 - Autoload contexts in several (sub)folders, possible ?

[RynnHeldeD]

Hello world :)

I am struggling since a few days to migrate my application to Behat 3.
I would like to use the new "several contexts by suite" feature to have a more flexible and reusable code. I would also like to organize my context classes into several folders for more readability as I will have many of them.

In theory

Below is an example of behat.yml and folders structures I would like to do :

# behat.yml

default:
    autoload:
            - %paths.base%/bootstrap
    suites:
        aWebSuite-dev:
            paths:
                - %paths.base%/features/someWebFeatures
            contexts:
                - aWebFeatureContext
                - EnvironmentContext:
                    - Dev
                - WebContext
                - UserContext

        aMobileSuite-dev:
            paths:
                - %paths.base%/features/someMobileFeatures
            contexts:
                - aMobileFeatureContext
                - EnvironmentContext:
                    - Dev
                - MobileContext
                - UserContext

And the folders structure:

behat/
|- bin/
|- bootstrap/
   |- features/
      |- aMobileFeatureContext.php
      |- anotherMobileFeatureContext.php
      |- aWebFeatureContext.php
   |- interfaces/
      |- WebContext.php
      |- MobileContext.php
   |- environments/
      |- EnvironmentContext.php
   |- Modules/
      |- UserContext.php
      |- anotherModuleContext.php
|- features/
   |- someWebFeatures/
      |- feature1.feature
      |- feature2.feature
   |- someMobileFeatures/
      |- feature1.feature
      |- feature2.feature

In practice

Such folders structure in bootstrap/ does not work because Behat is not able to find and load the context classes. I think I understood that it was because Behat 3 use PSR-0 autoloader to load the context classes from bootstrap/ and the structure above does not comply to PSR-0.

So for now, I am using the following structure :

behat/
|- bin/
|- bootstrap/
      |- aMobileFeatureContext.php
      |- anotherMobileFeatureContext.php
      |- aWebFeatureContext.php
      |- WebContext.php
      |- MobileContext.php
      |- EnvironmentContext.php
      |- UserContext.php
      |- anotherModuleContext.php

But every context files are mixing in the same folder. Is there still a way to achieve my first idea ?

Thanks a lot !

If your classes are autoloadable by your composer autoloader, they can be sued by Behat too, even when they don't follow PSR-0

Hi stof !

Thanks for your help ! I think I am missing something with PSR and autoloader...
I tried with the following configuration :

behat.yml

default:
    autoload:
            - %paths.base%/bootstrap/
    suites:
        test:
            paths:
                - %paths.base%/features/web
            contexts:
                - WebContext
                - FeatureContext

Structure

behat/
|- bin/
|- bootstrap/
   |- Features/
      |- FeatureContext.php
   |- Interfaces/
      |- WebContext.php
|- features/
   |- web/
      |- feature1.feature
      |- feature2.feature

composer.json

[...]
"autoload": {
      "psr-4": {
          "myCompany\\": "bootstrap/"
      }
    },

My class WebContext is in namespace myCompany\Interfaces and implements Behat\Behat\Context\Context. Same for FeatureContext (but it is in namespace myCompany\Features ).
I do run composer.phar update but I still get the following error :

 [Behat\Behat\Context\Exception\ContextNotFoundException]   
  `WebContext` context class not found and can not be used.  

What I am doing wrong ? :(

[stof]

this is because the name of your class is not WebContext but myCompany\Interfaces\WebContext as you put it in a namespace. So you need to fix the config referencing it

Oh, right. It works now !
Sorry for the newbie questions.

Below is the behat.yml working with the autoload and structure in my previous post, for people who may have the same problem :

default:
    autoload:
            - %paths.base%/bootstrap/
    suites:
        test:
            paths:
                - %paths.base%/features/web
            contexts:
                - myCompany\Interfaces\WebContext
                - myCompany\Features\FeatureContext

I still have other questions about Behat 3 but I think I should create other topics instead.
I close this issue, thanks a lot for helping stof !

Remember that you need to run php composer.phar dump-autoload if you modify your composer.json.
