Question

Rails 3.2.14 app。回购里面的黄瓜自动测试＆＃34;供应商＆＃34;夹。我需要解析*.feature个文件。

托尔任务

require './config/environment'
require "gherkin/tag_expression"
require "cucumber/runtime"
require 'cucumber'

class DB < Thor

  include Thor::Actions

  #...

  desc 'test', 'test'
  def generate_reports
    tag_expression = Gherkin::TagExpression.new(["@mytag"])
    file_list = get_list_of_files("features/myproject/")
    features_object = Cucumber::Runtime::FeaturesLoader.new(file_list, [], tag_expression)
    puts features_object.features[0].feature_elements.inspect
  end
end

运行任务时出错：

当我在IRB中执行该操作时，一切正常。问题是什么？或者是否有更好的方法来解析功能文件？

Answer 1

Cucumber告诉你，它无法找到你要求它解析的文件，我怀疑你的get_list_of_files方法正在返回.feature个文件的列表而没有路径？

比较这两个代码示例，其中存在功能features/a_feature.feature

f = Cucumber::FeatureFile.new("a_feature.feature")
f.parse([], [])

#=> Errno::ENOENT: No such file or directory - a_feature.feature. Please create a a_feature.feature directory to get started.

与...比较

f = Cucumber::FeatureFile.new("features/a_feature.feature")
f.parse([], [])

#=> Cucumber::Ast::Feature(...)

我认为如果您的get_list_of_files返回正确的相对路径，或者每个要素文件的完整路径，它应该按预期工作。

没有相应的文件和目录。黄瓜::运行时:: FeaturesLoader
