Lettuce BDD:如何在step.behave_as中添加'Examples:‘块？

Question

环境：Windows 8上的lettuce-0.2.23-py2.7

对于简单的场景(来自Lettuce文档的示例)，一切正常：

@step('I am logged in')
def is_logged_in(step):
    step.behave_as("""
        Given I go to the home page
          And I click the login button
          And I fill in username:{user} password:{pass}
          And I click "Login"
    """.format(user='floppy', pass='banana'))

但是我不知道如何通过像这样的多个示例传递Scenario Outline

Given cat with name "<cat_name>"
Examples:
  |cat_name|
  |filemon |
  |tomcat  |

在父场景中粘贴：

@step('I have bunch of cats')
    def bunch_of_cats(step):
        step.behave_as("""
            Given cat with name "<cat_name>"
               Examples:
                |cat_name|
                |filemon |
                |tomcat  |
        """.format()

StackTrace：

Traceback (most recent call last):
  File "build\bdist.win-amd64\egg\lettuce\core.py", line 144, in __call__
    ret = self.function(self.step, *args, **kw)
  File "\\features\steps\manager_steps.py", line 590, in magic
    """.format())
  File "build\bdist.win-amd64\egg\lettuce\core.py", line 408, in behave_as
    assert not steps_undefined, "Undefined step: %s" % steps_undefined[0].sentence
AssertionError: Undefined step: Examples:

看起来我需要在实现behave_as方法来识别轮廓的lettuce-0.2.23-py2.7.egg!\lettuce\core.py中搞乱了。

另一种解决方案是使用examples作为集合来实现step的for loop。有什么建议吗？

当然，这里有一段代码：

@step("Given cat with name (\w+)")
def set_cat_name(step, name):
    step.behave_as("""
        Given another step that requires a name of a cat {0}
    """.format(name))
