运行CTS测试需要做的准备工作有有:
1.下载完整的cts测试工具包,方式有两种:
a.在现有代码上编译,代码版本与目标机器版本一致;
b.在Google官网下载:http://source.android.com/compatibility/downloads.html,Compatibility Test Suite (CTS)即可。
2.下载media测试内容,还是上边的官网,在网页最下边:
CTS Media Files
These media files are required for the CTS media stress tests.
CTS Media 1.0
CTS Media Files
These media files are required for the CTS media stress tests.
CTS Media 1.0
3.连接手机与电脑(至少一台手机)
4.测试前准备
android-cts/repository/testcases中的CtsDelegatingAccessibilityService.apk和CtsDeviceAdmin.apk
安装完成以上apk后,在手机端操作:
a.设置->辅助程序->Delegating Accessibility Service,打开;
b.设置->安全->设备管理器->CTS相关的两个选项都激活;
c.打开USB调试模式;
d.保持屏幕唤醒;
e.允许模仿位置;
f.切换至英文模式US。
5.进入cts控制台
执行android-cts/tools/cts-tradefed
dev@linux-dev:~/android/CTS/android-cts/tools$ ./cts-tradefed
09-0509:20:52 I/: Detectednew device c8090fe4
09-0509:20:52 I/: Detectednew device5348300e
Android CTS 4.2_r1
09-0509:20:52 I/: Detectednew device c8090fe4
09-0509:20:52 I/: Detectednew device5348300e
Android CTS 4.2_r1
我现在连接着两台设备,都检测到了。
6.开始进行CTS测试
首先,在控制台中输入help看这个控制台都能干什么。
cts-tf > help
CTS-tradefed host version 4.2_r1
CTS-tradefed is the test harness for running the Android Compatibility Suite, built on top of the tradefed framework.
Available commands and options
Host:
help: show this message
help all: show the complete tradefed help
exit: gracefully exit the cts console, waiting till all invocations are complete
Run:
run cts --plan test_plan_name: run a test plan
run cts --package/-p: run a CTS test package
run cts --class/-c [--method/-m]: run a specific test class and/ormethod
run cts --continue-session session_ID: run all not executed tests from a previous CTS session
run cts [options] --serial/s device_ID: run CTS on specified device
run cts [options] --shards number_of_shards: shard a CTS run into given number of independent chunks, to run on multiple devices inparallel
run cts --help/--help-all: get more help on running CTS
List:
l/list d/devices: list connected devices and their state
l/list packages: list CTS test packages
l/list p/plans: list CTS test plans
l/list i/invocations: list invocations aka CTS test runs currentlyin progress
l/list c/commands: list commands: aka CTS test run commands currently in the queue waiting to be allocated devices
l/list r/results: list CTS results currently present in the repository
Add:
add derivedplan --plan plane_name --session/-s session_id-r [pass/fail/notExecuted/timeout]: derive a plan from the given session
Dump:
d/dump l/logs: dump the tradefed logsfor all running invocations
Options:
--disable-reboot: Do not reboot device after running some amount of tests.

run cts --plan + <plan name> 运行某个plan,查看当前支持的plan,运行l p,实际上所有的plan存放在android-cts/repository/plans;
run cts --package/-p 运行某一个测试包;
run cts --class/-c [--method/-m] 运行某一个测试类或测试方法;
run cts --continue-session session_ID 继续运行之前没有完成的CTS测试,要知道它的session_ID;
run cts [options] --serial/s device_ID 在某个串号的设备上进行CTS测试,对应多个机器的时候,通过adb devices能够查看当前连接的所有设备的串号;
run cts [options] --shards number_of_shards 在多个设备上同时运行CTS测试,如run cts --plan CTS --shards 2,在两个设备上同时运行;
run cts --help/--help-all 展示更多帮助
查看列表:
查看行为是l/list,接不同的参数显示对应信息。
d/devices 当前连接的设备,效果同adb devices,不过信息更详细,还有设备电量信息;
packages 当前CTS plan的所有测试包;
p/plan 当前所支持的CTS plan有哪些;
i/invocations 当前CTS的运行状态;
c/commands 展示出用户输入过的命令;
r/results 展示以往的测试结果
Session Pass Fail Not Executed Start time Plan name Device serial(s)

1 17907 64 0 2013.09.04_17.51.15 CTS FUSC85YLYPAMRC69
需要特别关注的几点注意事项:
- 首先,手机的功能一定要完整,WIFI BT 3G CAMERA等;
- 手机要切换至英文语言;
- 连接到可用WIFI;
- 有SIM卡,并能够打电话发短信;
- 对于屏幕密度,目前CTS中最高支持320,但实际上Google已经添加了对480,也就是1080p的支持;
- 会检测Fingerprint,注意厂家名;
- 要保证能够访问到www.google.com;
实战演戏:连接两台手机后,进入cts控制台:
run cts --plan CTS --shards 2
run cts --plan CTS --shards 2
两台手机上会同时跑起CTS测试,大概5小时候测试完成,生成测试报告,保存在results下。
