如果我有一个这样开始的场景:

  @my-tag

  Scenario Outline:
  Admin user changes email

    Given I register a random email address

...

是否可以阅读场景大纲文本或@my-tag单个步骤定义中的内容?例如,在I register a random email address步骤中,如果它在给定场景或标签值下运行,我想打印调试信息。

您不能直接从步骤定义中访问该信息。如果您需要这些信息,则必须在 before hook 期间捕获它。

黄瓜 v3+

下面的 before 钩子将捕获功能名称、场景/大纲名称和标签列表。请注意,此解决方案适用于 Cucumber v3.0+。对于早期版本,请参阅答案的末尾。

Before do |scenario|
  # Feature name
  @feature_name = scenario.feature.name

  # Scenario name
  @scenario_name = scenario.name

  # Tags (as an array)
  @scenario_tags = scenario.source_tag_names
end

例如,功能文件:

@feature_tag
Feature: Feature description

  @regular_scenario_tag
  Scenario: Scenario description
    Given scenario details

  @outline_tag
  Scenario Outline: Outline description
    Given scenario details
    Examples:
      |num_1  | num_2  | result |
      | 1        |   1       |   2     |

步骤定义为:

Given /scenario details/ do
     p @feature_name
     p @scenario_name
     p @scenario_tags
end

会给出结果:

"Feature description"
"Scenario description"
["@feature_tag", "@regular_scenario_tag"]

"Feature description"
"Outline description, Examples (#1)"
["@feature_tag", "@outline_tag"]

然后,您可以检查 @scenario_name 或 @scenario_tags 以了解您的条件逻辑。

黄瓜 v2

对于 Cucumber v2,所需的钩子更复杂:

Before do |scenario|
  # Feature name
  case scenario
    when Cucumber::Ast::Scenario
      @feature_name = scenario.feature.name
    when Cucumber::Ast::OutlineTable::ExampleRow
      @feature_name = scenario.scenario_outline.feature.name
  end

   # Scenario name
  case scenario
    when Cucumber::Ast::Scenario
      @scenario_name = scenario.name
    when Cucumber::Ast::OutlineTable::ExampleRow
      @scenario_name = scenario.scenario_outline.name
   end

  # Tags (as an array)
  @scenario_tags = scenario.source_tag_names
end

输出略有不同:

"Feature description"
"Scenario description"
["@regular_scenario_tag", "@feature_tag"]

"Feature description"
"Outline description"
["@outline_tag", "@feature_tag"]
