1CTS Trade Federation 2--------------------- 3 4CTS Trade Federation, cts-tradefed for short, is the next 5generation test harness for CTS. 6 7cts-tradefed is built on top of the Android Trade Federation test harness. 8 9It works in a similar manner to the prior CTS harness, but supports some 10advanced features such as: 11 12 - modular, flexible extensible design. cts-tradefed can be extended to 13support running CTS in a continuous test environment. 14 - supports sharding a CTS test run across multiple devices in parallel 15 - automatically continue a CTS test run on another device if connection 16is lost 17 18Configuring cts-tradefed 19------------------------ 20 211. Ensure 'adb' is in your current PATH. adb can be found in the 22Android SDK available from http://developer.android.com 23 24Example: 25 PATH=$PATH:/home/myuser/android-sdk-linux_x86/platform-tools 26 272. Follow the 'Setting up your device' steps documented in the 28CTS User Manual. The CTS User Manual can be downloaded at 29http://source.android.com/compatibility/downloads.html 30 313. Connect the device to the host machine. 32 334. Ensure device is visible via 'adb devices' 34 35Using cts-tradefed 36------------------- 37 38To run a test plan on a single device: 39 401. Make sure you have at least one device connected 412. Launch the cts-tradefed console by running the 'cts-tradefed'. If you've 42downloaded and extracted the CTS zip, the script can be found at 43 android-cts/tools/cts-tradefed 44Or else if you are working from the Android source tree and have run make cts, 45the script can be found at 46 out/host/linux-x86/cts/android-cts/tools/cts-tradefed 473. Type: 48'run cts' to run the default CTS plan 49 50Some other useful commands are 51 52To run a test module: 53'run cts --module <module_name>' 54 55To run a specific test: 56'run cts --test <test_name>' 57 58To shard a plan test run on multiple devices 59'run cts --shards <number of shards> 60note: all connected devices must be running the same build 61 62For more options: 63'run cts --help' 64 65CTS Tradefed Development 66------------------------ 67See http://source.android.com for instructions on obtaining the Android 68platform source code and setting up a build environment. 69 70The source for the CTS extensions for tradefed can be found at 71<android source root>/cts/tools/tradefed-host 72 73The source for the tradefed framework can be found on the 'tradefed' branch. 74 75Perform these steps to build and run cts-tradefed from the development 76environment: 77cd <path to android source root> 78make cts 79cts-tradefed 80 81More documentation and details on using and extending trade federation will 82be forthcoming in the near future. 83 84
