如何使用Highline测试Cucumber用户输入和输出？

Question

我尝试使用高线测试和阿鲁巴宝石来剔除标准输出，但仍然停止我的黄瓜测试并要求用户输入。使用Cucumber测试此类应用程序是否有最佳做法？

Answer 1

Aruba给了我解决方案。 首先，我的错误是在不检查if __FILE__ == $0的情况下创建应用程序根类的新实例。

最后它看起来像这样：

dashboard.feature:

Feature: Manage app with dashboard 
As an app user 
In order to control application 
I want to have a dashboard 

Scenario: View dashboard 
    When I run `../../lib/reporter.rb` interactively 
    Then I should see following choices 
    | 1 | Choice 1 | 
    | 2 | Choice 2 | 
    | 3 | Choice 3 | 

steps.rb:

Then(/^I should see following choices$/) do |table| 
    menu = '' 
    table.rows_hash.each do |key, value| 
    menu << "#{key}. #{value}\n" 
    end 
    Timeout::timeout(exit_timeout) do 
    loop do 
     break if assert_partial_output_interactive(menu) 
     sleep 0.1 
    end 
    end 
end
