如何在我的cucumber测试中使用yml文件？

我想在cucumber测试中使用config.yml文件。我是这样写的：

测试配置yml:

group_name: animals
learn_group_name: dogs
card_box_name: cats

require `watir-webdriver`
require `yaml`

def read_config
  config = YAML.load(File.read(`/home/profile/Desktop/cucumber/test_config.yml`))
  @group = config[`group_name`]
  @learn_group = config[`learn_group_name`]
  @card_box = config[`card_box_name`]
end

puts `Group = #{@group}`
puts `Learn group = #{@learn_group}`
puts `Card box = #{@card_box}`
...

Group = 
Learn group = 
Card box =
...

黄瓜试验。rb:

group_name: animals
learn_group_name: dogs
card_box_name: cats

require `watir-webdriver`
require `yaml`

def read_config
  config = YAML.load(File.read(`/home/profile/Desktop/cucumber/test_config.yml`))
  @group = config[`group_name`]
  @learn_group = config[`learn_group_name`]
  @card_box = config[`card_box_name`]
end

puts `Group = #{@group}`
puts `Learn group = #{@learn_group}`
puts `Card box = #{@card_box}`
...

Group = 
Learn group = 
Card box =
...

控制台（终端）：

group_name: animals
learn_group_name: dogs
card_box_name: cats

require `watir-webdriver`
require `yaml`

def read_config
  config = YAML.load(File.read(`/home/profile/Desktop/cucumber/test_config.yml`))
  @group = config[`group_name`]
  @learn_group = config[`learn_group_name`]
  @card_box = config[`card_box_name`]
end

puts `Group = #{@group}`
puts `Learn group = #{@learn_group}`
puts `Card box = #{@card_box}`
...

Group = 
Learn group = 
Card box =
...

但是怎么了？

这是一个非常糟糕的代码示例

您正在使用反勾号（`）而不是引号（“）。这将导致问题。很多问题

该问题与cucumber或watir webdriver gems无关。您正在方法（

read\u config

）中定义实例变量（

@group

…），但您从未调用该方法

请用更现实的例子更新问题

Before do
  @host                         ||= YML["host"]
  @group_name_for_search        ||= YML["group_name_for_search"]
  @learn_group_name_for_search  ||= YML["learn_group_name_for_search"]
  @card_box_name_for_search     ||= YML['card_box_name_for_search']
end

我必须先定义，然后再做黄瓜步骤
