<<-BLOCK
Feature: User logs in
  In order to post content
  As an user
  I want to log in

<< Here i want to iterate scenarios >>
BLOCK@H_404_3@ 
 
“scenario”是我想要循环的数组.对于我要打印的每个元素：
 
  
 
Scenario: #{scenario}
  Given
  When
  Then@H_404_3@ 
 
例如,如果“scenario”包含：
 
  
 
scenarios[0] = "User successfully logs in"
scenarios[1] = "User Failed to log in"@H_404_3@ 
 
我希望heredoc字符串是：
 
  
 
<<-BLOCK
Feature: #{feature}
  In order to #{in_order_to}
  As #{as}
  I want #{i_want}

Scenario: User successfully logs in
  Given
  When
  And

Scenarios: User Failed to log in
  Given
  When
  And
BLOCK@H_404_3@ 
 
如何在Ruby heredoc中进行迭代？
