1 CTS Trade Federation 2 --------------------- 3 4 CTS Trade Federation, cts-tradefed for short, is the next 5 generation test harness for CTS. 6 7 cts-tradefed is built on top of the Android Trade Federation test harness. 8 9 It works in a similar manner to the prior CTS harness, but supports some 10 advanced features such as: 11 12 - modular, flexible extensible design. cts-tradefed can be extended to 13 support 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 16 is lost 17 18 Configuring cts-tradefed 19 ------------------------ 20 21 1. Ensure 'adb' is in your current PATH. adb can be found in the 22 Android SDK available from http://developer.android.com 23 24 Example: 25 PATH=$PATH:/home/myuser/android-sdk-linux_x86/platform-tools 26 27 2. Follow the 'Setting up your device' steps documented in the 28 CTS User Manual. The CTS User Manual can be downloaded at 29 http://source.android.com/compatibility/downloads.html 30 31 3. Connect the device to the host machine. 32 33 4. Ensure device is visible via 'adb devices' 34 35 Using cts-tradefed 36 ------------------- 37 38 To run a test plan on a single device: 39 40 1. Make sure you have at least one device connected 41 2. Launch the cts-tradefed console by running the 'cts-tradefed' script at 42 android-cts/tools/cts-tradefed 43 3. Type: 44 'run cts --plan CTS' to run the default CTS plan 45 46 Some other useful commands are 47 48 To run a test package: 49 'run cts --package <packagename>' 50 51 To run a test class: 52 'run cts --class <full test class name>' 53 54 To shard a plan test run on multiple devices 55 'run cts --plan CTS --shards <number of shards> 56 note: all connected devices must be running the same build 57 58 For more options: 59 'run cts --help' 60 61 CTS Tradefed Development 62 ------------------------ 63 See http://source.android.com for instructions on obtaining the Android 64 platform source code and setting up a build environment. 65 66 The source for the CTS extensions for tradefed can be found at 67 <android source root>/cts/tools/tradefed-host 68 69 The source for the tradefed framework can be found on the 'tradefed' branch. 70 71 Perform these steps to build and run cts-tradefed from the development 72 environment: 73 cd <path to android source root> 74 make cts 75 cts-tradefed 76 77 More documentation and details on using and extending trade federation will 78 be forthcoming in the near future. 79 80
