Android N（7.0）CTS测试注意事项

一、PC端CTS测试的相关命令：

Compatibility Test Suite

CTS is the test harness for running the Android Compatibility Suite, built on top of Trade Federation.

Available commands and options
Host:
  help: show this message.（进入./cts-tradefed后输入help即可以查看以下全部命令）
  help all: show the complete tradefed help.
  version: show the version.
  exit: gracefully exit the compatibiltiy console, waiting until all invocations have completed.
Run:
  run <plan> --module/-m <module>: run a test module.（单独运行某个模块） 
  run <plan> --module/-m <module> --test/-t <test_name>: run a specific test from the module. Test name can be <package>.<class>, <package>.<class>#<method> or <native_name>.（运行一个特定的测试模块） 
  run <plan> --retry <session_id>: run all failed tests from a previous session.（测试上一个结果的所有失败项）
  run <plan> --help/--help-all: get help for Compatibility Test Suite.

  --serial/-s <device_id>: The device to run the test on.（当pc端插入多台设备时，可以指定在某个设备上运行测试，device_id指的是设备号）
  --abi/-a <abi>: The ABI to run the test against.
  --shards <shards>: Shards a run into the given number of independent chunks, to run on multiple devices in parallel.（此命令可以将测试包分为多部分，然后在多台设备上进行测试。比如我在pc端插入两台设备，则可以在进入./cts-tradefed后输入: run cts --plan CTS --shards 2 命令）
  --logcat-on-failure: Capture logcat when a test fails.(抓取测试失败时的logcat)
  --bugreport-on-failure: Capture a bugreport when a test fails.(抓取测试失败时的bugreport)
  --screenshot-on-failure: Capture a screenshot when a test fails.(对测试时的失败项进行截屏)
List:
  l/list d/devices: list connected devices and their state（列出所连接的设备和状态） 
  l/list m/modules: list test modules （列出测试模块） 
  l/list i/invocations: list invocations aka test runs currently in progress（列出正在运行的设备，及其所调用测试模块）
  l/list c/commands: list commands aka test run commands currently in the queue waiting to be allocated devices（列出正在等待分配任务的设备）

run cts -c android.telephony.cts.MmsTest -m testSendMmsMessage --skip-preconditions --disable-reboot   //测试单项时跳过检查预置条件和不重启手机

CTS测试时如果遇到有蓝牙等测试项一直测试不通过，可以尝试安装TxEddystone-UID-release-1.0.01 后再测试。
