Question

我是3的新手，我将它与symfony2扩展一起使用，并且一切正常，但我需要在测试期间知道抛出异常的消息。假设我想开发简单的博客，所以我需要列出所有帖子，然后我写了一个功能和一个以下场景：

Feature: Browse posts
In order to browse all posts on the site
As a Visitor on the site
I need a site which shows list of all posts

Scenario: Listing all posts
Given I am on "/post"
And The database is clean
And There are following posts:
| title                       | content                     |
| Testowy tytuł posta         | Testowa treść posta         |
| Testowy tytuł posta numer 2 | Testowa treść posta numer 2 |
Then the response status code should be 200
Then I should see "All posts" in the "title" element
And I should see "Listing all posts"
And I should see "Testowy tytuł posta"

我实现了所需的片段并且所有测试都通过了。好的，这次我需要在url中查看带有slug的博客文章，所以我将以下场景添加到上述功能中：

Scenario: View one post by slug
Given I am on "/post/testowy-tytul-posta"
Then the response status code should be 200
Then I should see "Testowy tytuł posta" in the "title" element
And I should see "Testowa treść posta"

此时我没有实体中的slug字段，测试不应该通过并且它可以工作，但是控制台的输出如下：

Scenario: View one post by slug                                  # src/MyVendor/BlogBundle/Features/blog/listing_posts.feature:18
Given I am on "/post/testowy-tytul-posta"                      # MyVendor\BlogBundle\Features\Context\FeatureContext::visit()
Then the response status code should be 200                    # MyVendor\BlogBundle\Features\Context\FeatureContext::assertResponseStatus()
  Current response status code is 500, but 200 expected. (Behat\Mink\Exception\ExpectationException)
Then I should see "Testowy tytuł posta" in the "title" element # MyVendor\BlogBundle\Features\Context\FeatureContext::assertElementContainsText()
And I should see "Testowa treść posta"

该行：

Current response status code is 500, but 200 expected

没有告诉我出了什么问题，当我使用-v选项运行behat命令（这会增加冗长度）时，它会给我以下输出：

Scenario: View one post by slug                                  # src/MyVendor/BlogBundle/Features/blog/listing_posts.feature:18
Given I am on "/post/testowy-tytul-posta"                      # MyVendor\BlogBundle\Features\Context\FeatureContext::visit()
Then the response status code should be 200                    # MyVendor\BlogBundle\Features\Context\FeatureContext::assertResponseStatus()
  Current response status code is 500, but 200 expected.

Then I should see "Testowy tytuł posta" in the "title" element # MyVendor\BlogBundle\Features\Context\FeatureContext::assertElementContainsText()
And I should see "Testowa treść posta"                         # MyVendor\BlogB

看起来有限，并没有显示所有的响应内容。如果有一个选项只接受异常消息，那将非常有用 - 在这种情况下：

Entity 'MyVendor\BlogBundle\Entity\Post' has no field 'slug'. You can therefore not call 'findOneBySlug' on the entities' repository

并将其输出到输出而不是resposne。

我需要做的就是在Behat \ MinkExtensio下添加behat.yml以下行：

[...]
Behat\MinkExtension:
    show_auto: true
    show_cmd: firefox %s
[...]

这将停止对失败步骤的测试，并打开具有给定结果的浏览器。

如何在Behat测试中获取异常消息
