我在这里张贴这个，尽管我在calabash github上发布了这个问题，因为已经有3个星期了，而且我没有听到任何支持。如果你看到我做错了，或者你遇到了同样的问题，请告诉我。目前我在ruby 1.9.3上运行Calabash-Android v 0.5.8。我已经在旧版本的Calabash-Android中对此进行了测试，但仍存在同样的问题。
我一直在努力研究提高我设置的测试的性能，我从一开始就从calabash发现的一个问题是应用程序似乎在 app_life_cycle_hooks.rb中重复调用< / strong>文件。每当我的测试运行时，就会生成测试服务器并启动应用程序，然后生成另一个测试服务器并重新启动应用程序。如果失败，则会截取两个屏幕截图而不是一个。以“-v”模式运行测试会显示这些调用两次（由下面的星号表示）：

下面你会找到我正在使用的 app_life_cycle_hooks 文件，没有重复通话的可能性，或者是什么，它是通过 calabash-android gen 创建的。我为屏幕添加了一个帮助器，它将在测试开始时将Android设备旋转到正确的方向，而不是在当前处于什么方向，但是这不应该影响产生多个服务器，因为代码可以被撕掉并且结果相同还是表明。引擎盖下的东西似乎多次访问我的* apps_life_cycle_hooks **文件。
#require 'calabash-android/management/adb'
require 'calabash-android/operations'
require_relative '../helpers/screen'
Before do |scenario|
if (scenario.source_tag_names.include?('@reset'))

end
start_test_server_in_background
$screen = Screen.new
$screen.rotate_to_proper_position()
end
After do |scenario|

print "Test failed: #{scenario.name}\n"
if scenario.exception.message =="HTTPClient::KeepAliveDisconnected" || scenario.exception.message =="EOFError"
puts "*********HTTP error!! attempting to restart test server!*************"
