如何debug android cts
启动和关闭ADB服务（adb start-server和adbkill-server）
经作者测试，模拟器在运行一段时间后，adb服务有可能（在Windows进程中可以找到这个服务，该服务用来为模拟器或通过USB数据线连接的真机服务）会出现异常。这时需要重新对adb服务关闭和重启。当然，重启Eclipse可能会解决问题，但那比较麻烦。如果想手工关闭adb服务，可以使用如下命令：
1. adb kill-server
在关闭adb服务后，要使用如下命令启动adb服务：
1. adb start-server
链接DLNA网络的命令：
ifconfig eth0 down; ifconfig eth0 hw ether 00:00:00:00:fd:87; ifconfig eth0 up; udhcpc
下面的方法是更适合RD 来debug CTS issue的cts运行方式, 这样解决了一个大问题: 如果用android传统方式去运行cts的话,必然已经被cts 运行环境占用了adb端口,用eclipsedebug就无法在另外一台机器上进行(例如RDPC, eclipse debug也需要adb ), 唯一的方式, 就是把android的source code搬到cts 运行的ubuntu机器上, 由于size特别大,非常不便.
下面介绍的运行方式, 直接用adb 去模拟 cts环境的运行方式, 唯一的缺点是, 一个test一个test 的运行. 但是, 对RD来说,这反而是优点! 方便快捷.
这个方法概括一下就是: 在我们的branch 上就有cts 的sourcecode, 我们可以修改其中某个test case所对应的 apk source, 之后,build 出 apk, 然后安装到板子上去run. 如果我们修改的testcase apk,就是添加了一些message/log之类的, 就立即可以在运行过程中体现出来. 同时,我们可以利用eclipse/ddms相结合 debug android framework部分, 当然, 由于我们也有apk的sourcecode, 也可以debug test case apk本身.
请参考:
剛做完實驗 , 寫下 SOP 給各位參考…
之後若有 RD 需要, 也可以參考這份….
Steps:
1)cmd> cd android/ics-4.x (到 android 目錄)
2)cmd>make cts
Q) 如何知道0801的cts 版本 ?
A)cmd> catandroid/ics-4.x/tools/tradefed-host/src/com/android/cts/tradefed/build/CtsBuildProvider.java| grepCTS_BUILD_VERSION
Result:public static final String CTS_BUILD_VERSION = "4.0.3_r2";
3)cmd>cd out/host/linux-x86/cts/android-cts/repository/testcases
4)找到需要測試的apk 並copy 到PC端file folder
Ex: CtsTestStubs.apk, CtsOsTestCases.apk, android.core.tests.runner.apk, CtsMyExampleTestCases.apk
5)確定PC 可用adb 連到target
6)
cmd>adbinstall CtsMyExampleTestCases.apk (安裝需要測試的 apk)
cmd>adb install CtsTestStubs.apk (這是google大多原生testapk 需要用到的 stub)
cmd>adbinstall CtsOsTestCases.apk
cmd>adbinstall android.core.tests.runner.apk
7)cmd>adb shell pm list instrumentation (用來查看已經安裝的instrumentation, 每個 CTS 用測的 apk 都是用instrumentation)
Result:
Instrumentation:com.android.cts.myexample/android.test.InstrumentationTestRunner (target=com.android.cts.myexample)
8)
整個 package 測試
cmd>adbshell am instrument –w –r com.android.cts.myexample/android.test.InstrumentationTest(執行該 test package)
此時可查看 failed (如下:Step8 test result example),也可透過 logcat log來看 fail (如下:[test result from logcat])
單一class測試
cmd> adb shellam instrument –e classandroid.myexample.cts.MySampleCalculatorTest–w –rcom.android.cts.myexample/android.test.InstrumentationTestRunner
cmd> adb shellam instrument –e classandroid.os.cts.MyHelloTest–w –rcom.android.cts.os/android.test.InstrumentationCtsTestRunner
單一function測試
cmd> adbshell am instrument –e classandroid.myexample.cts.MySampleCalculatorTest#testAdd–w –rcom.android.cts.myexample/android.test.InstrumentationTestRunner
9) 移除測試用 apk (cmd: adb uninstall<app_name> à <app_name>可從 target 端查詢: ls /data/app )
cmd> adb uninstall com.android.cts.os
cmd> adb uninstall com.android.cts.stub
cmd> adb uninstall com.android.cts.myexample
