Symfony Unit testing Service with mocks doesn't find the class name

Question

I try to test on a pure unit test my Symfony Service (located in src/AppBundle/Services/CapthaServiceAdapter ):

namespace AppBundle\Services;

use AppBundle\Interfaces\CapthaBuilderInterface;
use Symfony\Component\HttpFoundation\Session\Session;
use Gregwar\Captcha\CaptchaBuilder;

/**
* The following class is an adapter for Gregwar Captcha Builder
* I do not set Gregwar's Captha Builder as a Service
* Because I want to stay hidden fromt he service container.
*/
class CapthaServiceAdapter implements CapthaBuilderInterface
{

  const IMAGE_INLINE=0;
  const IMAGE_NORMAL=1;

  /**
  * @var Session;
  */
  private $session=null;

  /**
  * @var CaptchaBuilder
  */
  private $capthaBuilder=null;

  public function __construct(Session $sessionManager)
  {
    $this->session=$sessionManager;
    $this->capthaBuilder=new CaptchaBuilder();
  }

  /**
  * @inheritdoc
  * @throws \InvalidArgumentException when type is not either self::IMAGE_INLINE or self::IMAGE_NORMAL
  */
  public function build($identifier,$type)
  {
    if($type!==self::IMAGE_INLINE || $type!==IMAGE_NORMAL){
      throw new \InvalidArgumentException("Type should be either CapthaService::IMAGE_INLINE or CapthaService::IMAGE_NORMAL you provided the value: ".$type);
    }

    $this->builder->build();
    $this->session->set($sessionKey,$this->builder->getPhrase());

    if($type==self::IMAGE_INLINE){
      return $this->builder->inline();
    }

    return $this->builder->output();
  }

  /**
  * @inheritdoc
  */
  public function verify($identifier,$value)
  {
    $capthaSessionValue=$session->get($identifier);
    return $capthaSessionValue && $value===$capthaSessionValue;
  }

}

So I did the following Test case (located in tests/AppBundle/Services/CapthcaServiceTest.php ):

namespace Tests\AppBundle\Services;

use PHPUnit\Framework\TestCase;
use AppBundle\Services\CapthaServiceAdapter;
use Symfony\Component\HttpFoundation\Session\Session;


class CapthcaServiceTest extends TestCase
{

  private function getServiceForBuild()
  {
    $mock=$this->createMock(Session::class);
    return new CapthaServiceAdapter($mock);
  }

  public function testBuildInline()
  {
    $service=$this->getServiceForBuild();
    $capthaValue=$service->build('somevalue',CapthaService::IMAGE_INLINE);

     $this->assertRegExp('/^data:image\/jpeg;base64,(?:[A-Za-z0-9+\/]{4})*(?:[A-Za-z0-9+\/]{2}==|[A-Za-z0-9+\/]{3}=)$/i',$element);
  }
}

But when I try to run it I get the following error:

Error: Class 'AppBundle\\Services\\CapthaServiceAdapter' not found

So how I can make my test to look for my class?

Also my pgpunit.xml contains the following content:

<?xml version="1.0" encoding="UTF-8"?>

            </exclude>
        </whitelist>
    </filter>
</phpunit>

Edit 1

By doing changes mentioned in the comments (updated the code above) I get the error:

Error: Class 'Tests\\AppBundle\\Services\\CapthaService' not found

Do you know how I can fix that?

Edit 2:

I also have seen this answer so I post my composer.json as well:

            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
        ],
        "post-install-cmd": [
            "@symfony-scripts"
        ],
        "post-update-cmd": [
            "@symfony-scripts"
        ]
    },
    "config": {
        "sort-packages": true
    },
    "extra": {
        "symfony-app-dir": "app",

        "symfony-var-dir": "var",
        "symfony-web-dir": "web",
        "symfony-tests-dir": "tests",
        "symfony-assets-install": "relative",
        "branch-alias": null
    }
}

As you can see it has the autoloading class as well:

"autoload": {
            "psr-4": {
                "AppBundle\\": "src/AppBundle"
            },
            "classmap": [
                "app/AppKernel.php",
                "app/AppCache.php"
            ]
        },
        "autoload-dev": {
            "psr-4": {
                "Tests\\": "tests/"
            },
            "files": [
                "vendor/symfony/symfony/src/Symfony/Component/VarDumper/Resources/functions/dump.php"
            ]
        },

Also By changing into this:

"autoload": {
        "psr-4": {
            "AppBundle\\": "src/AppBundle",
            "AppBundle\\Services":"src/AppBundle/Services",
        },
        "classmap": [
            "app/AppKernel.php",
            "app/AppCache.php"
        ]
    },

Results into this error:

Error: Class 'Tests\\AppBundle\\Services\\CapthaService' not found

Hos I can make the phphunit to look into the appropriate namespace?

Answer 1

Over your code there is a line that mentions:

$capthaValue=$service->build('somevalue',CapthaService::IMAGE_INLINE);

The class CapthaService where is defined? Did you mean CapthaServiceAdapter (perhaps leftover from a refactor?)

Change into that and that should be fine.
