如何将解析的小黄瓜保存为特征文件(Ruby)

Question

我需要以编程方式修改黄瓜的特征文件。我已经使用gherkin的gem 'gherkin/parser‘解析了一个特征文件。

我发现的问题是，在解析之后，我最终得到了一个哈希，其中包含以下数据作为示例：

{:type=>:GherkinDocument, :feature=>{:type=>:Feature, :tags=>[], :location=>{:line=>1, :column=>1}, :language=>"en", :keyword=>"Feature", :name=>"MyFeature", :description=>"  As an user\n  I want to test a feature", :children=>[{:type=>:Scenario, :tags=>[{:type=>:Tag, :location=>{:line=>5, :column=>3}, :name=>"@MyTag"}], :location=>{:line=>6, :column=>3}, :keyword=>"Scenario", :name=>"My scenario", :steps=>[{:type=>:Step, :location=>{:line=>7, :column=>5}, :keyword=>"Given ", :text=>"I start the app"}, {:type=>:Step, :location=>{:line=>8, :column=>5}, :keyword=>"And ", :text=>"I generate a test user"}, {:type=>:Step, :location=>{:line=>9, :column=>5}, :keyword=>"And ", :text=>"I finish the flow"}]}]}, :comments=>[]}

有没有可能将解析器生成的这个GherkinDocument转换为纯文本特征文件来保存它？我应该使用什么方法或gem来获取

根据docs的说法，您将使用Ruby Gherkin::Pickles::Compiler

require 'gherkin/parser'
require 'gherkin/pickles/compiler'
parser = Gherkin::Parser.new
gherkin_document = parser.parse("Feature: ...")
# Make changes to gherkin_document
pickles = Gherkin::Pickles::Compiler.new.compile(gherkin_document)
