<h2 id=cts_tradefed>Using the CTS tradefed</h2>
<p>See the <a
href="{@docRoot}devices/tech/test_infra/tradefed/index.html">Trade Federation
Overview</a> for an explanation of the Trade Federation (tradefed or TF for
short) continuous test framework.</p>

<p>To run a test plan:</p>
<ol>
  <li>Connect at least one device.
  <li>Press the <strong>home</strong> button to set the device to the home screen at the start of CTS.
  <li>While a device is running tests, it must not be used for any other tasks
    and must be kept in a stationary position (to avoid triggering sensor activity)
    with the cameras pointing at an object that could be focused.
  <li>Do not press any keys on the device while the CTS is running. Pressing keys
    or touching the screen of a test device will interfere with the running tests
    and may lead to test failures.
  <li>Launch the CTS console by running the <em>cts-tradefed</em> script from
    the folder where the CTS package has been unzipped, e.g.
    <code>$ ./android-cts/tools/cts-tradefed</code>
  <li>You may start the default test plan (containing all of the test packages) by
    appending: <code>run cts --plan CTS</code> This will kick off all the CTS tests required for compatibility.
    Enter <code>list plans</code> to see a list of test plans in the repository.
    Enter <code>list packages</code> to see a list of test packages in the repository.
    See the CTS command
    reference or type help for a complete list of supported commands.
  <li>Alternately, you may run the CTS plan of your choosing from the command line
    using: <code>cts-tradefed run cts --plan
      <plan_name>
      </code>
<p class="note"><strong>Note:</strong> When running Android 6.0 (Marshmallow)
CTS only, we recommend you use the <code>--skip-preconditions</code> option to
skip the experimental pre-conditions feature that may cause issues for when
executing CTS tests.</p>
  <li>View test progress and results reported on the console.
  <li>If your device is Android 5.0 or later and declares support for an ARM and a
    x86 ABI, you should run both the ARM and x86 CTS packages.
</ol>
<h2 id=selecting_cts_plans>Selecting CTS plans</h2>
<p>The following test plans are available:</p>
<ul>
  <li><em>CTS</em>—all tests required for compatibility. </li>
  <li><em>Signature</em>—the signature verification of all public APIs </li>
  <li><em>Android</em>—tests for the Android APIs </li>
  <li><em>Java</em>—tests for the Java core library </li>
  <li><em>VM</em>—tests for ART or Dalvik </li>
  <li><em>Performance</em>—performance tests for your implementation </li>
</ul>
<p>These can be executed with the <code>run cts</code> command.</p>
