CTS 全稱(Compatibility Test Suite)，兼容性測試工具，其目的就是讓各種Android設備廠商能夠開發出兼容性更好的Android設備，同時，Google也提供了一份兼容性標準文檔（Compatibility Definition Document, CDD）Android設備只有滿足CDD的規定並且通過CTS，才能獲得Android的商標和享受Android Market的權限。
環境準備：
1、安裝ubantu環境
2、安裝openjdk8
opendjk8的安裝按照google官方文檔是需要ubuntu version >15.04，在v>15.04時，可以直接使用下述命令進行openjdk8的安裝。
$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk
也可以去oracle官網下載相應的jdk進行安裝（需要配置環境變量）
3、Android SDK安裝
android sdk 百度雲盤地址：https://pan.baidu.com/s/1G0kvpx81ZAX-XCVydDl0Dw 密碼：hmwe
解壓之後，設置環境變量
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.下載CTS測試套件
百度雲盤地址：https://pan.baidu.com/s/1Y0ReCIHvdiuzIP59R83ggA 密碼：91la
官方地址 http://source.android.com/compatibility/cts/downloads.html
下載之後解壓。解壓路徑：/home/psp/cts/android-cts
5、單項測試操作步驟
a、測試之前，確保adb 連接到電腦
psp@ubuntu:~$ adb devices
List of devices attached
18137B451D device
b、之後執行以下命令：
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、然後在cts-tf > 後執行測試命令:cts-tf > run cts -m CtsAppTestCases -t android.app.cts.SystemFeaturesTest#testNfcFeatures
“-m” ：意思就是我們要測試的模塊
“-t”:意思就是我們的測試的類
“#後面的方法”：我們要測試類中的方法。
如果要想執行某一個模塊的測試項，直接用-m參數，其它參數就不需要了。如果想測試某一個類的話，需要加上-m 和-t的參數了。
輸出如下：
cts-tf > run cts -m CtsAppTestCases -t android.app.cts.SystemFeaturesTest#testNfcFeatures
