如何在 Robot Framework 中运行小黄瓜风格的测试用例

Question

是否必须执行一些配置设置才能让 Robot Framework (RF) 运行 Gherkin/BDD 风格的测试用例？

我已经在 Windows 7 上安装了 RF 2.8.3，并且在 Selenium2Library 和 DatabaseLibrary 上运行正常。根据用户文档和网络上的其他信息，我应该能够编写和运行 Gherkin 风格的测试。但是，当我这样做时，我会出错。在尝试匹配关键字之前，RF 不会去除 Gherkin 关键字（Given、When、Then、...）：

Tests.Group001 GeneralTests
==============================================================================
Scenario: No template operation selected                              | FAIL |
No keyword with name 'But page does not contain a no template operation selected error message' found.
------------------------------------------------------------------------------

我使用直截了当的方式运行测试：

pybot ../Tests

我的示例测试文件是：

*** settings ***

Library     Selenium2Library
Library     DatabaseLibrary
Library     kw_common

*** Test Cases ***

Scenario: No template operation selected
    Given I have logged in and I have selected to perform template configuration
    When I do not select a template operation
    But page does not contain a no template operation selected error message
    And I press the next button
    Then I should not see a template operation selected error message


*** Keywords ***

I have logged in and I have selected to perform template configuration
    Log     Given I have logged in and I have selected to perform template configuration

I do not select a template operation
    Log     No template operation selected

page does not contain a no template operation selected error message
    Page Should Not Contain     'ddTemplateOperation' is required.

I press the next button
    Click Element               xpath=//input[contains(@id,'next')]

I should not see a template operation selected error message
    Page Should Contain     'ddTemplateOperation' is required.

帮助将不胜感激。谢谢。

从官方文档http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#ignoring-given-when-then-and-but-prefixes：

当搜索匹配的关键字时，前缀 Given、When、Then 和 And 将被删除

所以page does not contain a no template operation selected error message关键字需要重命名为But page does not contain a no template operation selected error message.
