运行CTS测试需要做的准备工作有有:
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。
CTS Media Files
These media files are required for the CTS media stress tests.
CTS Media 1.0
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。
执行android-cts/tools/cts-tradefed

Android CTS 4.2_r1
我现在连接着两台设备,都检测到了。
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

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
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。
