About how to integrate android test into LAVA

by YongQin Liu

Hi, All LAVA is an automated validation architecture, and it now has a test framework for running android test tools and parsing the test output. Please NOTE that lava-android-test is just used for running the test tools, parsing the test output, and formatting the test result. Here I will describe how to write and add a test wrapper script for lava-android-test, and how to integrate the test into LAVA. 1. checkout the lava-android-test to your local machine bzr branch lp:lava-android-test 2. if the test tools are just command that can be run on android system, and the output is well formatted, then congratulations, you can go directly to step 6. You don't need to wrapper script again. 3. If the test tools has already been build into the android image or in the host image(normal Ubuntu image), then you won't need to define some scripts for organizing the test tools, you can skip this step, Otherwise, put the actual test tools in some place, normally they are in a sub directory of test_definitions, like the busybox test: the actual test tool is busybox_test.sh, and it is put in the * lava_android_test/test_definitions/busybox *directory 4. add a test wrapper script for your test into the test_definitions directory. like busybox.py: The content of the wrapper script should be something like below: Normally, you just need to redefine the red and bold part in the above. ############################################################################################### import os import lava_android_test.testdef test_name = '*test_sample'* #linux commands that will be run on the host before INSTALL_STEPS_ADB_PRE" *INSTALL_STEPS_HOST_PRE = []* #adb commands that will be run before install apk file into android *INSTALL_STEPS_ADB_PRE = []* #APK file path list that will be intalled into android *APKS= []* #adb commands that will be run before install apk file into android *INSTALL_STEPS_ADB_POST = []* #linux commands that will be run on the host after INSTALL_STEPS_ADB_POST *INSTALL_STEPS_HOST_POST = []* #linux commands that will be run on the host before RUN_STEPS_ADB_PRE *RUN_STEPS_HOST_PRE = []* #adb commands that will be run before install apk file into android *RUN_STEPS_ADB_PRE = []* #commands that will be run on android *ADB_SHELL_STEPS = []* #adb commands that will be run before install apk file into android *RUN_STEPS_ADB_POST = []* #linux commands that will be run on the host after RUN_STEPS_ADB_POST *RUN_STEPS_HOST_POST = []* #pattern to parse the command output to generate the test result. PATTERN =* **"^\s*(?P<test_case_id>\w+)=(?P<result>\w+)\s*$"* inst = lava_android_test.testdef.AndroidTestInstaller(steps_host_pre= INSTALL_STEPS_HOST_PRE, steps_adb_pre=INSTALL_STEPS_ADB_PRE, apks=APKS, steps_adb_post=INSTALL_STEPS_ADB_POST, steps_host_post=INSTALL_STEPS_HOST_POST) run = lava_android_test.testdef.AndroidTestRunner(steps_host_pre= RUN_STEPS_HOST_PRE, steps_adb_pre=RUN_STEPS_ADB_PRE, adbshell_steps=ADB_SHELL_STEPS, steps_adb_post=RUN_STEPS_ADB_POST, steps_host_post=RUN_STEPS_HOST_POST) parser = lava_android_test.testdef.AndroidTestParser(PATTERN) testobj = lava_android_test.testdef.AndroidTest(testname=test_name, installer=inst, runner=run, parser=parser) ############################################################################################### And in the command part, you can use "$(SERIAL)" to represent the device serial number, like: RUN_STEPS_HOST_POST = [ 'python %s/android-0xbenchmark/android_0xbenchmark_wait.py $(SERIAL)' % curdir] and "$(OPTIONS)" to represent the option string passed from command line. Like INSTALL_STEPS_HOST_PRE = [ 'echo $(OPTION)'], RUN_STEPS_HOST_PRE = [ 'echo $(OPTION)'], then you can run *lava-android-test install -o "install options string" *or* **lava-android-test run -O "run options string"* *Note:* * B**ecause lava-android-test will be run on lava-lab, and there will be multiple devices connected simultaneously,* * So we should consider to pass the device serial number for each test tools.* * If the test tools is defined for steps_adb_pre/adbshell_steps/steps_adb_post,* * then there is no need to pass the device serial number,** lava-android-test will do this for you.* 5. you can use "lava-android-test list-tests" to check if the test wrapper created can be recognized, use "lava-android-test install ${test_name}" to install the test, use "lava-android-test run ${test_name}" to execute the test, use "lava-android-test show ${result_id}" to show the output the test executed, use "lava-android-test parse ${result_id}" to to generate the result bundle for the test executed. And here is a blog about install/test lava-android-test that you can reference: http://www.linaro.org/linaro-blog/2011/12/01/local-lava-testing-of-android-… 6. When you have done the above steps and verified your test that works well, then you can integrate it in LAVA with the android-build. Here is a description about that. https://wiki.linaro.org/Platform/Android/AndroidBuild-LavaIntegration If you have any questions, please contact me. Also I have copied it to google docs, https://docs.google.com/a/linaro.org/document/d/1kVyuFZtnMsganZaszQZhgX3QPO… you can comment directly there.

Which kernel should outside developers use?

by Chris Simmonds

Hello, I am working on behalf of an SoC vendor and I am trying to work out which (if any) of the many git trees at http://git.linaro.org/gitweb we should base our work on. I would like to use the Linaro code base because the arch/arm support is ahead of mainline. But I also need a degree of stability. Ideally I would like a "long term support" Linaro kernel. Since that doesn't exist, one approach is use the linux-linaro-tracking tree but only use the linux-linaro-3.0* tagged versions so that we can easily merge in changes from v3.0 from kernel.org linux-stable. So my questions are 1. Is this a rational approach? 2. Is this how you imagine other projects interfacing with Linaro? Or should we really be waiting for Linaro code to be mainlined and pulling from kernel.org? Bye for now, Chris Simmonds

Flyswatter2 + origen board

by Subash Patel

Hello, I am interested to know if anyone from Linaro has attempted using Flyswatter2 on origen board. I am trying to use openocd for origen board, and found issues as early as in reading tapid. Any pointers/help on this is appreciated. Note: I saw some discussion on this in irc-logs, but I couldn't get any response on irc yesterday. Regards, Subash

Linaro embedded Linux distro?

by Zach Pfeffer

During ELC a few people asked me if Linaro had something bigger than nano and smaller than Ubuntu that they could use to build stuff. Of course I said Android, but a lot of people actually want a regular Linux platform where they can easily recompile what they need to hack on, add their own libs and scripts and generally work in an "embedded, cross build way." I know there's OpenEmbedded and I've heard of something called "livebuild." Does anyone have anymore info? This class of users is arguably the largest class of people using these boards so creating something targeted at them would allow them to get all the benefits of Linaro in a easy to use fashion. -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Announcing the release of live-build_3.0~a45-1-1linaro3 to ppa:linaro-maintainers/tools Included in this release are two minor but important fixes 1) for cross builds make sure to qualify the use of the linaro-overlay ppa correctly so armel isn't hardcoded 2) for precise, defend against the movement of insserv out of the system path, which if not present will cause packages such as module-init-tools to fail. -- Regards, Tom "Where's the kaboom!?
