CTS如何继续上一次测试

       在用cts测试安卓系统的时候，由于测试时间较长，会遇到各种各样的问题，导致cts测试中断了。那么cts中断了是不是只能重新测试呢？答案是否定的。

通过运行“./android-cts/tools/cts-tradefed”命令打开cts终端，输入“help”命令就能看到cts支持的命令：

cts-tf > topeet@ubuntu:~/Android_test$ ./android-cts/tools/cts-tradefed Android CTS 4.4_r311-08 14:07:25 I/: Detected new device 0123456789ABCDEFcts-tf > helpCTS-tradefed host version 4.4_r3CTS-tradefed is the test harness for running the Android Compatibility Suite, built on top of the tradefed framework.Available commands and optionsHost:  help: show this message  help all: show the complete tradefed help  exit: gracefully exit the cts console, waiting till all invocations are completeRun:  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 CTSList:  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 repositoryAdd:  add derivedplan --plan plane_name --session/-s session_id -r [pass/fail/notExecuted/timeout]: derive a plan from the given sessionDump:  d/dump l/logs: dump the tradefed logs for all running invocationsOptions:  --disable-reboot : Do not reboot device after running some amount of tests.cts-tf > 

其中的

run cts --continue-session session_ID: run all not executed tests from a previous CTS session

告诉你输入这个命令就能继续上一次未执行完的测试，不过这个命令需要一个”session_ID“，那么 ”session_ID“又是什么，你输入"list results"就能看到以下内容：

cts-tf > l rSession  Pass   Fail  Not Executed  Start time           Plan name  Device serial(s)  0        20556  226   4115          2017.11.05_20.58.29  CTS        unknown           1        24567  330   0             2017.11.06_17.23.22  CTS        unknown  

原来session_ID是你曾经运行过的测试计划，这个测试计划用一个数字表示，我上次测试的日期是“2017.11.05_20.58.29”，故session_ID是0，那么在终端输入

run cts --continue-session 1

就能继续上一次未完成的测试。

测试完毕后会提示你测试结果存放的目录
