背景介绍

Calabash-android是支持android的UI自动化测试框架。

gearman

$ sudo apt-get install gearman-job-server
$ gearmand -V
?
gearmand 1.0.6 - https://bugs.launchpad.net/gearmand
?
$ sudo apt-get install gearman-tools
$ gearman -H
?
启动gearman job server，作为后台服务运行:

$ sudo gearmand -d
?
多手机同步测试举例

假设要测试微信的发送消息功能，calabash的测试用例可以按如下方式撰写：
?
AA-send-message-to-BB–role-AA.feature：

Feature: 微信测试发送消息给好友-角色A
?
? Scenario: 微信测试发送消息给好友
? ? ...打开微信软件，作为帐号A登录，进入与好友B的聊天窗口
? ? When I send weixin message "A说，你好！"? # 微信聊天窗口中发送消息
? ? And? I send sync message "A说，你好！" to role "BB"
? ? Then I see "A说，你好！"? #我能看到自己说的话
?
? ? When I wait sync message $AA_sync_1 as role "AA"
? ? Then I see $AA_sync_1 #我能看到对方说的话
? ? ...
?
AA-send-message-to-BB–role-BB.feature：

Feature: 微信测试发送消息给好友-角色B
?
? Scenario: 微信测试发送消息给好友
? ? ...打开微信软件，作为帐号B登录，进入与好友A的聊天窗口
? ? When I wait sync message $BB_sync_1 as role "BB"
? ? Then I see $BB_sync_1? #我能看到对方说的话
?
? ? When I send weixin message "B说，你好！"? # 微信聊天窗口中发送消息
? ? And? I send sync message "B说，你好！" to role "AA"
? ? Then I see "B说，你好！"? #我能看到自己说的话
? ? ...
?
命令行终端1中运行AA-send-message-to-BB–role-AA.feature

$ export ADB_DEVICE_ARG=HTC-G9
$ export GEARMAN_JOB_SERVER=localhost
?
$ calabash-android run weixin.apk -r features/ features/AA-send-message-to-BB--role-AA.feature
?
命令行终端2中运行AA-send-message-to-BB–role-BB.feature

$ export ADB_DEVICE_ARG=HWAWEI-P7
$ export GEARMAN_JOB_SERVER=localhost
?
$ calabash-android run weixin.apk -r features/ features/AA-send-message-to-BB--role-BB.feature
?
calabash中封装gearman命令实现同步机制
?
sync_step.rb:

# encoding: utf-8

? fail "环境变量::GEARMAN_JOB_SERVER::未定义！ 设置方法: export GEARMAN_JOB_SERVER=localhost" if ( gearman_job_server == nil)
? uuid=`uuidgen`.strip?
? cmd="gearman -h #{gearman_job_server} -t 30000 -w -c 1 -f receiver_#{role} -- tee /tmp/#{role}-#{uuid}; cat /tmp/#{role}-#{uuid}"
? puts "角色#{role}准备执行命令：#{cmd}"
?
? message=`#{cmd}`.strip
? fail "未收到同步消息" if ( message == "" )

? puts "角色#{role}接收到同步消息: #{ENV[msg_ev]}"
end
?

end

calabash_steps.rb：

# encoding: utf-8
require 'calabash-android/calabash_steps'
?
Then /^I see \$([^\$]*)$/ do |text_ev|
? text = ENV[text_ev]
? steps %{
? Then I see "#{text}"
