当我尝试使用MinkContext扩展Behat FeatureContext时,“step already defined”错误

标签: behat mink

我是Behat和Mink的新手,我正在尝试使用MinkContext扩展FeatureContext,但是当我这样做时,每一步都会抛出一个错误,指出MinkContext中定义的第一个函数也是在FeatureContext中定义的(它不是' T)。错误消息如下:

Step "/^(?:|I )am on (?:|the )homepage$/" 
is already defined in FeatureContext::iAmOnHomepage()

如果我从类中删除第一个函数,每个步骤都会抛出相同的错误,但现在它引用了MinkContext类中的第二个函数:

Step "/^(?:|I )am on "(?P<page>[^"]+)"$/" 
is already defined in FeatureContext::visit()

使用RawMinkContext扩展FeatureContext可以正常工作。

导致这种情况的原因是什么?

----编辑(附加信息)------------

我正在使用Behat 3.

这是我当前的整个FeatureContext.php,我仍然收到错误。我搜索了包含Behat安装的整个文件夹,我只能找到

的一个实例
<?php

use Behat\Behat\Context\Context;
use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;

/**
 * Defines application features from the specific context.
 */
class FeatureContext extends MinkContext implements SnippetAcceptingContext
{
    /**
     * Initializes context.
     *
     * Every scenario gets its own context instance.
     * You can also pass arbitrary arguments to the
     * context constructor through behat.yml.
     */
    public function __construct()
    {
        date_default_timezone_set("US/Eastern");
    }



}

这是我的behat.yml文件:

# behat.yml
default:
    extensions:
        Behat\MinkExtension:
            goutte: ~
            selenium2: ~
            base_url: https://harvest.cals.ncsu.edu/
    suites:
        default:
            contexts:
            - FeatureContext
            - Behat\MinkExtension\Context\MinkContext

这是MinkContext.php的顶部:     命名空间Behat \ MinkExtension \ Context;

use Behat\Behat\Context\TranslatableContext;
use Behat\Gherkin\Node\TableNode;

/**
 * Mink context for Behat BDD tool.
 * Provides Mink integration and base step definitions.
 *
 * @author Konstantin Kudryashov <ever.zet@gmail.com>
 */
class MinkContext extends RawMinkContext implements TranslatableContext
{
    /**
     * Opens homepage
     * Example: Given I am on "/"
     * Example: When I go to "/"
     * Example: And I go to "/"
     *
     * @Given /^(?:|I )am on (?:|the )homepage$/
     * @When /^(?:|I )go to (?:|the )homepage$/
     */
    public function iAmOnHomepage()
    {
        $this->visitPath('/');
    }
...

---编辑2:工作版本------------

FeatureContext.php:

    <?php

    use Behat\Behat\Context\Context;
    use Behat\Behat\Context\SnippetAcceptingContext;
    use Behat\Gherkin\Node\PyStringNode;
    use Behat\Gherkin\Node\TableNode;
    use Behat\MinkExtension\Context\MinkContext;
    use Behat\Mink\WebAssert;

    /**
     * Defines application features from the specific context.
     */
    class FeatureContext extends MinkContext implements Context, SnippetAcceptingContext
    {
    ...

behat.yml(现在使用Selenium标签转到enable Chrome

# behat.yml
default:
    extensions:
        Behat\MinkExtension:
            goutte: ~
            selenium2: 
                wd_host: "http://127.0.0.1:4444/wd/hub"
                # chrome
                capabilities: { "browserName": "chrome", "browser": "chrome", "version":  "25", 'chrome': {'switches':['--no-sandbox']}}
            base_url: https://harvest.cals.ncsu.edu/
            browser_name: chrome
    suites:
        default:
            contexts:
            - FeatureContext

答案 0 :(得分:1)

似乎MinkContext被加载了两次:在FeatureContext和behat.yml中 如果从behat.yml中删除MinkContex,它应该可以工作。
