php – 仅在使用Behat时发生语义错误

我正在使用Symfony2.当我使用浏览器(firefox)手动访问页面时：

http://localhost:8000/vendor/add-product

页面呈现正常,我看到一个表单,允许用户将产品添加到他的商店.

但是当我使用Behat进行测试时,我收到此错误：

[Semantical Error] The annotation “@SymfonyComponentValidatorConstraintsGreaterThanOrEqual”
in property AppBundleEntityProduct::$productPrice does not exist,
or could not be auto-loaded.

这是相关源代码(的一部分)：

namespace AppBundleEntity;

use DoctrineORMMapping as ORM;
use SymfonyComponentValidatorConstraints as Assert;
use SymfonyBridgeDoctrineValidatorConstraintsUniqueEntity;

/**
* @ORMEntity
* @ORMTable(name="app_products")
*/
class Product
{
    /**
    * @ORMId
    * @ORMColumn(type="integer")
    * @ORMGeneratedValue(strategy="AUTO")
    */
    private $productId;

    /**
    * @ORMColumn(type="integer")
    * @ORMManyToOne(targetEntity="AppBundleEntityStore")
    */
    private $storeId;

    /**
    * @ORMColumn(type="string",length=255)
    * @AssertNotBlank(message="This is important,Product Name should not be blank!")
    * @AssertLength(max = "255",maxMessage="Your description must not exceed 255 characters.")
    */
    private $productName;

    /**
    * @ORMColumn(type="integer",length=255)
    * @AssertGreaterThanOrEqual(value=0)
    * @AssertNotBlank(message="Product Price should not be blank!")
    */
    private $productPrice;

    /**
    * @ORMColumn(type="string",length=255)
    * @AssertNotBlank(message="Please enter a product description.")
    * @AssertLength(max = "255",maxMessage="Your description must not exceed 255 characters.")
    */
    private $productDescription;

    /**
    * @ORMColumn(type="integer")
    * @AssertGreaterThanOrEqual(value=0)
    * @AssertNotBlank(message="Product Quantity should not be blank!")
    */
    private $productQuantity;

    /**
    * @ORMColumn(type="string",length=255)
    * @AssertFile(mimeTypes={ "image/jpeg" })
    * @AssertFile(maxSize="6000000")
    */
    private $productImage;
    ...

这是我的特色：

Feature: Buying products
As a customer,I want to view and select products before buying,So that I could have more value for my money

Background:
    Given I am on the homepage
    When I fill in "username" with "24thsaint"
    And I fill in "password" with "123123"
    And I press "login-button"

Scenario: Vendor wants to add a new product
    Given I am on the homepage
    When I follow "My Store" ###### The test stops here as I get the Semantical Error
    And I follow "add-new-product"

请帮忙,我真的觉得一切都到位了.只是在使用Behat进行测试期间发生了错误.什么可能出错？

编辑：

我通过清除缓存做了先生Evgeniy Kuzmin的建议.我跑了,

php bin/console cache:clear --env=test

之前通过的测试现在失败,出现此错误：

[Semantical Error] The annotation "@DoctrineORMMappingEntity" in 
class AppBundleEntityUser does not exist,or could not be auto-loaded.

请帮我.
