CTS 全称(Compatibility Test Suite)，兼容性测试工具，其目的就是让各种Android设备厂商能够开发出兼容性更好的Android设备，同时，Google也提供了一份兼容性标准文档（Compatibility Definition Document, CDD）Android设备只有满足CDD的规定并且通过CTS，才能获得Android的商标和享受Android Market的权限。
环境准备：
1、安装ubantu环境
2、安装openjdk8
opendjk8的安装按照google官方文档是需要ubuntu version >15.04，在v>15.04时，可以直接使用下述命令进行openjdk8的安装。
$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk也可以去oracle官网下载相应的jdk进行安装（需要配置环境变量）
3、Android SDK安装
android sdk 百度云盘地址：https://pan.baidu.com/s/1G0kvpx81ZAX-XCVydDl0Dw 密码：hmwe
解压之后，设置环境变量
psp@ubuntu:~$ gedit ~/.bashrc
export ANDROID_SDK_HOME=/home/psp/androidTool/android-sdk-linux
export PATH=$PATH:${ANDROID_SDK_HOME}/tools
export PATH=$PATH:${ANDROID_SDK_HOME}/platform-tools
export PATH=$PATH:${ANDROID_SDK_HOME}/build-tools/24.0.1
4.下载CTS测试套件
百度云盘地址：https://pan.baidu.com/s/1Y0ReCIHvdiuzIP59R83ggA 密码：91la
官方地址 http://source.android.com/compatibility/cts/downloads.html
下载之后解压。解压路径：/home/psp/cts/android-cts
5、单项测试操作步骤
a、测试之前，确保adb 连接到电脑
psp@ubuntu:~$ adb devices
List of devices attached
18137B451D device
b、之后执行以下命令：
psp@ubuntu:~$ cd cts/android-cts/
psp@ubuntu:~/cts/android-cts$ ls
logs results testcases tools
psp@ubuntu:~/cts/android-cts$ cd tools/
psp@ubuntu:~/cts/android-cts/tools$ ./cts-tradefed
Android Compatibility Test Suite 7.1_r18 (4800211)
08-09 00:50:13 I/DeviceManager: Detected new device 18137B451D
cts-tf >
c、然后在cts-tf > 后执行测试命令:cts-tf > run cts -m CtsAppTestCases -t android.app.cts.SystemFeaturesTest#testNfcFeatures
“-m” ：意思就是我们要测试的模块
“-t”:意思就是我们的测试的类
“#后面的方法”：我们要测试类中的方法。
如果要想执行某一个模块的测试项，直接用-m参数，其它参数就不需要了。如果想测试某一个类的话，需要加上-m 和-t的参数了。
输出如下：
cts-tf > run cts -m CtsAppTestCases -t android.app.cts.SystemFeaturesTest#testNfcFeatures

d、相关log和results会保存到以下路径
psp@ubuntu:~/cts/android-cts$ ls
