Calabash+Gearman實現多手機同步測試機制

摘要：

Calabash-android是支持android的UI自動化測試框架，但不支持多手機同步測試。本文介紹如何利用任務分發系統Gearman的消息同步機制，配合Gearman實現多手機同步測試機制。

背景介紹

Calabash-android是支持android的UI自動化測試框架。 http://www.oschina.net/p/calabash-android

Gearman是一個分發任務的程序框架，能夠用在各類場合，與Hadoop相比，Gearman更偏向於任務分發功能。它的 任務分佈很是 簡單，簡單得能夠只須要用腳本便可完成。 http://www.oschina.net/p/gearman

Ubuntu上安裝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

啓動gearman job server，做爲後臺服務運行:

$ sudo gearmand -d

多手機同步測試舉例

假設要測試微信的發送消息功能，calabash的測試用例能夠按以下方式撰寫：

AA-send-message-to-BB--role-AA.feature：

Feature: 微信測試發送消息給好友-角色A
 
  Scenario: 微信測試發送消息給好友
    ...打開微信軟件，做爲賬號A登陸，進入與好友B的聊天窗口
    When I send weixin message "A說，你好！"   # 微信聊天窗口中發送消息
    And  I send sync message "A說，你好！" to role "BB"
    Then I see "A說，你好！"  #我能看到本身說的話

    When I wait sync message $AA_sync_1 as role "AA"
    Then I see $AA_sync_1 #我能看到對方說的話
    ...

AA-send-message-to-BB--role-BB.feature：

Feature: 微信測試發送消息給好友-角色B
 
  Scenario: 微信測試發送消息給好友
    ...打開微信軟件，做爲賬號B登陸，進入與好友A的聊天窗口
    When I wait sync message $BB_sync_1 as role "BB"
    Then I see $BB_sync_1  #我能看到對方說的話

    When I send weixin message "B說，你好！"   # 微信聊天窗口中發送消息
    And  I send sync message "B說，你好！" to role "AA"
    Then I see "B說，你好！"  #我能看到本身說的話
    ...

命令行終端1中運行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

命令行終端2中運行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中封裝gearman命令實現同步機制

sync_step.rb:

# encoding: utf-8
require 'calabash-android/calabash_steps'

When /^I wait sync message \$([^\$]*) as role "([^\"]*)"$/ do |msg_ev, role|
  gearman_job_server=ENV["GEARMAN_JOB_SERVER"]
  fail "環境變量::GEARMAN_JOB_SERVER::未定義！ 設置方法: 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}準備執行命令：#{cmd}"

  message=`#{cmd}`.strip
  fail "未收到同步消息" if ( message == "" )
  ENV[msg_ev]=message
  puts "角色#{role}接收到同步消息: #{ENV[msg_ev]}"
end

When /^I send sync message "([^\"]*)" to role "([^\"]*)"$/ do |msg, role|
  gearman_job_server=ENV["GEARMAN_JOB_SERVER"]
  fail "環境變量::GEARMAN_JOB_SERVER::未定義！ 設置方法: export GEARMAN_JOB_SERVER=localhost" if ( gearman_job_server == nil)
  fail "sync message 爲空" if ( msg == "" )
  cmd="echo '#{msg}' | gearman -h #{gearman_job_server} -t 30000 -f receiver_#{role}"
  puts "角色#{role}準備執行命令：#{cmd}"

  response=`#{cmd}`.strip
  fail "發送同步消息失敗" if ( response != msg )
  puts "發送同步消息給角色#{role}: #{msg}"
end

When /^I send sync message \$([^\$]*) to role "([^\"]*)"$/ do |msg_ev, role|
  gearman_job_server=ENV["GEARMAN_JOB_SERVER"]
  fail "環境變量::GEARMAN_JOB_SERVER::未定義！ 設置方法: export GEARMAN_JOB_SERVER=localhost" if ( gearman_job_server == nil)
  msg=ENV[msg_ev]
  response=`echo "${msg}" | gearman -h #{gearman_job_server} -f receiver_#{role}`
  fail "發送同步消息失敗" if ( response != msg )
  puts "發送同步消息給角色#{role}: #{msg}"
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}"
  }
end
