【我分享】使用 Gearman+Calabash 并行测试手机 APP
摘要：使用任务分发系统Gearman分布式执行Calabash的自动化测试用例，可以达到并行测试手机APP的目的。背景介绍GearmanGearman是一个分发任务的程序框架，可以用在各种场合，与Hadoop相比，Gearman更偏向于任务分发功能。它的 任务分布非常简单，简单得可以只需要用脚本即可完成。
CalabashCalabash-android是支持android的UI自动化测试框架，PC端使用了cucumber框架，通过http和json与模拟器和真机上安装的测试apk通信，测试apk调用robotium的方法来进行UI自动化测试，支持webview操作。
calabash脚本以 使用calabash测试开源中国Android客户端 为例。
Gearman安装和执行测试Ubuntu上安装Gearman$ sudo apt-get install gearman-job-server$ gearmand -Vgearmand 1.0.6 - https://bugs.launchpad.net/gearmand $ sudo apt-get install gearman-tools$ gearman -H运行Gearman并发执行Calabash测试用例启动gearman job server，作为后台服务运行:
$ gearmand -d启动两个worker，每个woker代表一个手机测试设备(tester)，woker始终不退出，且没有任何打印:
$ gearman -w -f tester -- ./test-case.sh NEXUS-7 testdata-aa.bashrc$ gearman -w -f tester -- ./test-case.sh HUAHEI-8860 testdata-bb.bashrc分发测试用例到各个worker，收集到所有测试打印后，即完成测试：
./run-suite.sh @BVT实时查看测试结果，任何一个worker测试完一个用例，测试结果会立即打印出来：
tail -f /tmp/test-result并发测试的效果：
理论上如果顺序执行测试所有用例要10个小时，那么只要准备10个手机，每个手机对应启动一个worker:tester，测试时间将缩短到最少1个小时。
下面的脚本是在同一台Ubuntu电脑上，利用多个USB口连接多个手机来并发测试，
如果要在多台电脑上执行并发测试，那要考虑这多台电脑如何获取同一份apk和calabash脚本，可以考虑从一个公共的url去wget。
Gearman测试脚本test-case.sh从stdin接收到的calabash测试脚本文件路径，调用calabash-android完成测试，再作为client调用printer
