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.
