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Calabash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。
Gearman是一個分發任務的程序框架,可以用在各種場合,與Hadoop相比,Gearman更偏向於任務分發功能。它的 任務分布非常 簡單,簡單得可以只需要用腳本即可完成。
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
啟動gearman job server,作為後台服務運行:
$ 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的測試用例可以按如下方式撰寫:
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,作為帳號A登錄,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!" #我能看到自己說的話
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,作為帳號B登錄,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!" #我能看到自己說的話
...
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
