Android（26）
为了保证开发的应用在所有兼容Android的设备上正常运行，并保证一致的用户体验，Google制定了CTS（Compatibility Test Suite）来确保设备运行的Android系统全面兼容Android规范，Google也提供了一份兼容性标准文档（Compatibility Definition Document, CDD）。
在进行CTS之前，需要先从google官网下载相关文件，需要自卑梯子翻墙。下载链接：
。目前最新的版本是Android5.1的版本，主要包含ARM和X86架构的，如果你的设备这两种架构的都包含，那么都需要测试一下。由于手头的机器是Android4.4的版本，因此下载了Android4.4的CTS进行测试。
大部分是基于Junit和仪表盘技术编写的。还扩展了自动化测试过程，可以自动执行用例，自动收集和汇总测试结果。CTS采用XML配置文件的方式将这些测试用例分组成多个测试计划（plan）,第三方也可以创建自己的plan。
CTS测试执之前要做的准备工作如下：
<span style="color:#. 下载兼容性测试用例包，并解压，解压后的文件名命名为“android-cts”。
<span style="color:#. 重置手机（恢复出厂设置）。
<span style="color:#. 去掉谷歌账户。
<span style="color:#. 设置手机语言为英语：Setting-&Language&input-&language-&English(UnitedStates)。
<span style="color:#. 插入SIM卡和外置SD卡（SD卡需要&#26684;式化：Settings-&Storage-&EraseSD
card-&Erase SD card-&Erase Everything）。
<span style="color:#. 插入USB,连接手机到电脑，可以用adb devices检查，是否正确连接。
<span style="color:#. 打开wifi,并连接到可用wifi。
<span style="color:#. 打开蓝牙，无须配对。
<span style="color:#. 保证手机无操作<span style="color:#分钟后LCDoff:Settings-&Display-&Sleep-&30 minutes.
<span style="color:#. 去掉屏幕锁：Settings-&Security-&ScreenLock的&#20540;是“None”.
<span style="color:#. 打开Settings-&Locationservices-&“Google location services”, ”GPS satellites”, ”Location &Google search”.
<span style="color:#. 打开Settings-&Accessibility-&Developeroptions-&USB debugging(USB调试).
<span style="color:#. 打开Settings-&Accessibility-&Developeroptions-&Stay Awake（保持唤醒）.
<span style="color:#. 打开Settings-&Accessibility-&Developeroptions-&Allow mock location（允许模拟位置）.
<span style="color:#. 通过Settings-&Speechsynthesis-&Install voice data安装“Text To Speech”文件（com.svox.langpack.installer-1.apk）,假如android-cts/repository/testcases/中没有此文件，就省去这一步。
<span style="color:#. 如果需要执行可访问性方面的兼容性测试，则安装“CtsDelegatingAccessibilityService.apk”（adbinstall –r */android-cts/repository/testcases/CtsDelegatingAccessibilityService.apk），并将Settings-&Accessibility-&DelegatingAccessibility
Service选项打开。
<span style="color:#. 如果需要执行设备管理方面的兼容性测试，则安装“CtsDeviceAdmin.apk” (adb install –r*/android-cts/repository/testcases/ CtsDeviceAdmin.apk)，并将Setting-&Security-&DevicesAdministrators-&android.devicesadmin.cts.CtsDevicesAdmin等选项打开。
TestCase里面包含很多的测试用例，可以全部测试，也可以只测试部分。
做完了前面的准备工作之后，就可以开始CTS测试了。测试之前，先把Android SDK中adb的路径加入系统的环境变量中，然后键入：
#adbdevices
查看已识别已经连接的设备。
进入到“android-cts/tools”目录，接着执行
#./cts-tradefed
接着运行测试设备解码方面的测试用例：
#runcts --class android.media.cts.DecoderTest
可以发现红色箭头所指的部分测试用例已经通过，有些命令不熟悉的话可以键入help。当该单元下的测试用例都完成以后，可以键入：
#cts-tf& l r
查询测试结果，如下图所示：
查看android-cts/repository/results/目录，可以发现生成的XML文件：
把testResult.xml文件拖入Safari浏览器中，可以很方便的查看测试结果：

上面的assert部分为断言，用来检查cts的测试结果是pass还是fail。你会发现cts的测试比较简单，它只能保证 你的android设备支持wifi，和中间件接口控制wifi的工作。
搜遍了wifi的全部测试模块，都没有找到哪里验证了 WifiConfiguration.KeyMgmt （wifi鉴权）。
官方说明cts覆盖范围：
/compatibility/cts-intro.html#areas-covered
它对Platform API只能确保 接口参数定义正确、类名正确、属性和
正确、容错处理正确。 它没法保证我的功能会正常。因为功能都传递给了native层代码处理。&
Areas Covered
The unit test cases cover the following areas to ensure compatibility:
Description
Signature tests
For each Android release, there are XML files describing the signatures of all public APIs contained in the release. The CTS contains a utility to check those API signatures against the APIs available on the device. The results from signature checking are
recorded in the test result XML file.
Platform API Tests
Test the platform (core libraries and Android Application Framework) APIs as documented in the SDK Class Index to ensure API correctness, including correct class, attribute and method signatures, correct method behavior, and
negative tests to ensure expected behavior for incorrect parameter handling.
Dalvik VM Tests
The tests focus on testing the Dalvik VM
Platform Data Model
The CTS tests the core platform data model as exposed to application developers through content providers, as documented in the SDKandroid.provider package: contacts, browser, settings, etc.
Platform Intents
The CTS tests the core platform intents, as documented in the SDK Available Intents.
Platform Permissions
The CTS tests the core platform permissions, as documented in the SDK Available Permissions.
Platform Resources
The CTS tests for correct handling of the core platform resource types, as documented in the SDKAvailable Resource Types. This includes tests for: simple values, drawables, nine-patch, animations, layouts, styles and themes, and loading alternate resources.
