Rails 3.2.14 app. Repo with cucumber autotests在"vendor"文件夹中。我需要解析*.feature文件。
雷神任务
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task时的错误:

当我在IRB中执行该操作时，一切都有效。有什么问题吗?或者是否有更好的方法来解析特征文件?
Cucumber告诉你，它找不到你要求它解析的文件，我怀疑你的get_list_of_files方法正在返回一个没有路径的.feature文件列表?
比较这两个代码示例，其中存在一个特性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.
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，或每个功能文件的完整路径，它应该像您期望的那样工作。
