resume :暂停套件演示和调试，并具有恢复功能

Question

作为一名软件测试人员，我希望能够在测试执行过程中的任何阶段暂停使用want进行测试执行，以便调试失败的测试，并在演示过程中向客户展示更详细的特性。

Scenario: Pause suite mid demo, then resume
 Given I am in a meeting to show off a new feature our team has developed
 And a client asks us a question about the page we are currently on
 When I press the 'p' key in the terminal
 Then I should have enough time to answer the question in detail to the client
 And I should be able to resume test execution by pressing the 'enter' key in the terminal

Scenario: Pause suite at a known point for debugging
 Given there is a failed test
 When I add the "pause" method to the step definition
 Then the test should pause execution until pressing the 'enter' key in the terminal

Answer 1

这里的两个函数在Windows上工作，在大多数其他操作系统上也是如此。

# Checks for a pause command in the command line and if it has been pressed, will pause
def paused?
    if STDIN.ready?
      last_input = STDIN.gets
      while last_input == 'p'
        sleep 1
      end
    end
end

# Pauses for debugging, will continue when enter is pressed
def pause
  print 'p'
  last_input = STDIN.gets
  while last_input == 'p'
    sleep 1
  end
end

当在每个步骤定义的开始处放置一次时，第一个步骤提供了在完成步骤后通过在终端中按'p‘来直接暂停的能力。

或者，创建一个抽象库可能会产生更好的结果，因为可以在整个过程中使用paused?方法在执行过程中暂停其他点，而不是新步骤的开始。当按下'p‘以外的任何标准键时，这将恢复，但是我建议使用一个新行。

第二，只需暂停测试，直到按下任何键，此时，执行可以恢复--是调试的理想选择。

停下来愉快！

您可以尝试使用AfterStep钩

AfterStep('@pauseable') do
  answer = 'n'
  begin
    Timeout.timeout 1 do # wait for a second for user to press 'p'
      answer = STDIN.getch
    end
  rescue Timeout::Error  # answer is 'n' when no key is pressed during 1 second
  end

  STDIN.getch if answer == 'p' # wait until user presses any key
end

现在，您可以将您的特性标记为@pauseable。运行它并按p暂停它。然后按任意键继续
