我正在尝试编写一个小型红宝石宝石,使用Bundler和Thor进行模板生成。我正在用Cucumber和Aruba写测试,而我很难让它们通过。
我在应用程序中定义了以下Thor CLI类:
require 'thor'
require 'sleipnir'
require 'sleipnir/generators/layout'
require 'sleipnir/generators/app'
module Sleipnir
class CLI < Thor
desc "app", "Generates an app directory and copies the appropriate files"
def app(app_name)
Sleipnir::Generators::App.start([app_name])
end
desc "layout", "Generates specific layout based on template type"
def layout(template_type)
Sleipnir::Generators::Layout.start([template_type])
end
end
end
这是app.rb
文件:
require 'thor/group'
module Sleipnir
module Generators
class App < Thor::Group
include Thor::Actions
argument :app_name, :type => :string
class_option :template_type, :default => :erb, :required => true
def self.source_root
File.dirname(__FILE__)
end
def create_app_dir
empty_directory(app_name)
end
def copy_app_scaffold
directory("app", app_name)
end
end
end
end
layout.rb
文件:
require 'thor/group'
module Sleipnir
module Generators
class Layout < Thor::Group
include Thor::Actions
class_option :template_type, :default => :erb, :required => true
def self.source_root
File.dirname(__FILE__) + "/template"
end
def copy_layout
template_type = options[:template_type]
template("layout_template.#{template_type}", "views/layout.#{template_type}")
end
end
end
end
我为app
方法编写了黄瓜测试,然后通过。但是,layout
方法失败了。这是测试:
Feature: Generate
In order to generate templates
As a CLI
I want to run the generator
Scenario: Layout
When I run `sleipnir app test_app`
Then the following directories should exist:
| test_app/views |
When I run `sleipnir layout --template_type "erb"`
Then the following files should exist:
| test_app/views/layout.erb |
测试的第一部分传递得很好(即创建了目录),但是关于验证文件的部分存在失败。我检查了文件结构,layout_template.erb
文件存在,所以我无法弄清楚为什么它没有被正确模板化。
答案 0 :(得分:0)
不幸的是,Aruba不支持:https://github.com/cucumber/aruba/issues/140。
但是编写自己的步骤定义并不是很糟糕,只需要在传入的命令之前首先执行。请参阅https://github.com/cucumber/cucumber/wiki/Step-Definitions以获取示例。
