ruby - 如何使用 Highline 测试 Cucumber 用户输入和输出？

Question

我尝试了几种方法，例如存根 STDOUT、使用 highline-test 和 aruba gem，但它仍然会停止我的黄瓜测试并要求用户输入。是否有使用 Cucumber 测试此类应用程序的最佳实践？

Answer 1

Aruba 给了我解决方案。首先，我的错误是创建应用程序根类的新实例而不检查if __FILE__ == $0.

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
