<p>The Android for Work (AfW) Test Harness is a test suite for validating the
AfW compatibility of Android devices. It includes support apps, test cases,
configuration files, and a test runner (<code>afw-test-tradefed</code>) built on
<code>cts-tradefed</code>. You should setup and run the AfW Test Harness after
completing <a href="{@docRoot}devices/tech/admin/provision.html">Provisioning
for Device Administration</a>.</p>

<p class=note><strong>Note:</strong> Building and running the AfW Test Harness
is similar to building and running the Android
<a href="http://source.android.com/compatibility/cts/index.html">Compatibility
Test Suite (CTS)</a>.</p>

<h2 id=setup_env>Setting up a development environment</h2>
<p>The development environment for the AfW Test Harness is similar to Android
OS. Follow the steps in
<a href="{@docRoot}source/requirements.html">Requirements</a> to set up a
development machine.</p>

<h2 id=download_source>Downloading source code</h2>
<p>Download the AfW Test Harness source code using the steps in
<a href="{@docRoot}source/downloading.html">Downloading the Source</a>. The AfW
Test Harness source code is in the <code>./test/AfwTestHarness</code> project.
The branch name determines the version of AfW Test Harness to download (each
Android platform has a separate version of AfW Test Harness). For Android 7.0,
the branch name is <code>afw-test-harness-nougat-dev</code>. To initialize
the repo and download source code for this branch, use:</p>

<pre>
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
$ git config --global user.name "Your Name"
$ git config --global user.email "you@example.com"
$ repo init -u https://android.googlesource.com/platform/manifest -b afw-test-harness-nougat-dev
$ repo sync -j24
</pre>

<p>To check out the source code for a different version, specify the branch with
the corresponding tag. Available branches include:</p>

<table>
<tr>
<th>Branch Name</td>
<th>Supported Android Platform</td>
</tr>
<tr>
<td>afw-test-harness-nougat-dev</td>
<td>Android 7.0</td>
</tr>
<tr>
<td>afw-test-harness-2.1</td>
<td>Android 7.0</td>
</tr>
<tr>
<td>afw-test-harness-marshmallow-dev</td>
<td>Android 6.0</td>
</tr>
<tr>
<td>afw-test-harness-1.5</td>
<td>Android 6.0</td>
</tr>
</table>

<p>Other dependency projects required to build the harness are also downloaded
with the source code.</p>

<h3 id=view_studio>Viewing in Android Studio</h3>
<p>To view and edit AfW source code in Android Studio:</p>
<ol>
<li>Run the following commands
<pre>
$ make idegen
$ development/tools/idegen/idegen.sh
</pre>
</li>
<li>In Android Studio, open <code>android.ipr</code>.</li>
</ol>

<p>The AfW Test Harness source code is in <code>test/AfwTestHarness</code>.</p>

<h2 id=config_harness>Configuring the AfW Test Harness</h2>
<p>You can customize the harness by configuring
<code>test/AfwTestHarness/afw-test.props</code>. To run the harness
successfully, complete the following steps:</p>
<ol>
<li>Configure the Wi-Fi network in <code>afw-test.props</code> with the
following properties:
<pre>wifi_ssid
wifi_password (optional)
wifi_security_type (optional, available options are: NONE, WEP or WPA)
</pre>
</li>
<li>Obtain at least one account from a domain that is bound to Test DPC as
its device policy controller. Specify the details in <code>afw-test.props</code>
with the following properties:
<pre>
work_account_username
work_account_password
</pre>
<p>The AfW Test Harness uses Test DPC to test provisioning flows, so accounts
<strong>must</strong> bind to Test DPC to run the test harness.</p>
</li>
</ol>

<h2 id=build_harness>Building the AfW Test Harness</h2>
<p>Initialize the build configuration using:</p>
<pre>
$ source build/envsetup.sh
$ lunch
</pre>

<p>Select a device type and press <strong>Enter</strong>.</p>

<p>Build the harness using:</p>
<pre>$ make afw-test-harness -j32</pre>
<p>This creates a directory (<code>out/host/linux-x86/afw-th/android-cts</code>)
with all necessary binaries, configuration files, and tools to run the test
harness. This directory is also zipped into a file
(<code>out/host/linux-x86/afw-th/android-afw-test-harness.zip</code>)
for distribution.</p>

<h2 id=run_harness>Running the AfW Test Harness</h2>
<p>Use the following steps to run the AfW Test Harness:</p>
<ol>
<li>In your build environment, launch the test runner using:
<pre>$ afw-test-tradefed</pre>
This starts the <code>cts-tf</code> console, loads test plans, test cases,
and <code>afw-test.props</code> from
<code>out/host/linux-x86/afw-th/android-cts</code>.</li>
<li>From the unzipped folder of <code>android-afw-test-harness.zip</code>,
launch the test runner using:
<pre>$ cts-tf &gt; ./android‐cts/tools/afw-test‐tradefed</pre>
This loads test plans, test cases, and <code>afw-test.props</code> from
<code>android-cts</code> directory. Ensure
<code>./android‐cts/repository/testcases/afw-test.props</code> has the work
account and Wi-Fi configuration.</li>

<li>Run a test plan. Each test plan is an XML file that contains a set of test
packages from the <code>AfwTestHarness/tests</code> test package directory.
Common plans include:

<ul>
<li><code><strong>afw-userdebug-build</code></strong>. Contains all test
packages that require a userdebug build.</li>
<li><code><strong>afw-user-build</code></strong>. Runs on a user build but
requires the test device to be set up properly, including completing the initial
setup and enabling USB debugging.</li>
</ul>

<br>To run the test plan <code>afw-userdebug-build</code>, use:
<pre>$ cts-tf &gt; run cts --plan afw-userdebug-build</pre>
To see all test plans, use the command <code>list plans</code>. To view plan
definitions, refer to
<code>out/host/linux-x86/afw-th/android-cts/repository/plans</code>.
<br>
</li>
<li>Run a test package. To run a single test package, use
<pre>$ cts-tf &gt; run cts --package com.android.afwtest.NfcProvisioning
</pre>
To view all packages, use the command <code>list packages</code>. For more
options, use the command <code>run cts --help</code>.</li>
</ol>

<h2 id=debug_harness>Debugging the AfW Test Harness</h2>
<p>Run all commands in the afw-test-tradefed console (<code>cts-tf</code>),
which you can launch by running <code>afw-test-tradefed</code>.</p>
<ul>

<li>Display more information with the <code>-l INFO</code> or <code>-l
DEBUG</code> flags. Example:
<pre>$ cts-tf &gt; run cts ‐‐plan afw-userdebug-build -l DEBUG</pre></li>

<li>Run the test harness on a specific device with the <code>-s</code> flag.
Example:
<pre>$ cts-tf &gt; run cts ‐‐plan afw-userdebug-build -l DEBUG -s device_sn</pre>
</li>

<li>Run test harness on all connected devices with the
<code>--all-devices</code> flag. Example:
<pre>$ cts-tf &gt; run cts ‐‐plan afw-userdebug-build -l DEBUG --all-devices</pre>
</li>

<li>View current running executions using <code>list invocations</code> or
<code>l i</code>.</li>

<li>View summary of past test executions using <code>list results</code> or
<code>l r</code>.</li>

<li>View other <code>list</code> commands using <code>help list</code>.</li>

<li>Monitor real-time logcat with filter using <code>afwtest</code>, then open
another terminal and start logcat using: <code>adb logcat | grep afwtest</code>.
After a test completes:
<ul>
<li>View logs in
<code>out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em></code>.
The full device logcat and host log (<code>afw-test-tradefed</code> logs) are
saved in separate zip files.</li>

<li>Find relevant information by searching the device logcat for
<strong>afwtest</strong>. Example: <code>zless
out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em>/device_logcat_<em>random-number</em>.zip
| grep afwtest</code></li>

<li>To view the full afw-test-tradefed log, use: <code>zless
out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em>/host_log_<em>random-number</em>.zip</code>
</li>
</ul>
</li>
<li>A test package automates an AfW provisioning flow by going through UI pages
and recording a navigation log in the device logcat file for each page.
Example: <code>afwtest.AutomationDriver:
Navigating:com.android.afwtest.uiautomator.pages.gms.AddAccountPage</code>
<br>UI pages for test package
<code>com.android.afwtest.NfcProvisioning</code> include:<ul>
<li>
<code>com.android.afwtest.uiautomator.pages.managedprovisioning.NfcProvisioningPage</code>
</li>
<li><code>com.android.afwtest.uiautomator.pages.PageSkipper</code></li>
<li><code>com.android.afwtest.uiautomator.pages.LandingPage</code></li>
</ul>
</li>
<li>If a test failed during the provisioning process, logcat contains an error
similar to:
<pre>TestRunner: java.lang.RuntimeException: Failed to load page: com.android.afwtest.uiautomator.pages.packageinstaller.DeviceAccessPage
</pre>
This is typically caused by errors in a previous UI page or the page that
failed to load, so try to find other error messages in logcat before this error,
then try to reproduce it manually following the provisioning flow.</li>
<li>If a test package fails:
<ul>
<li>A screenshot is saved to
<code>out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em></code>
using the following syntax:
<code>screenshot-test_<em>test_class_full_name</em>_<em>test_case_name</em>-<em>random_number</em>.png</code>.
This information is also logged in the host log.</li>
<li>A bug report is saved to
<code>out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em></code>
as:
<code>bug-<em>test_class_full_name</em>_<em>test_case_name</em>-<em>random_number</em>.zip</code>.
</li>
</ul>
</li>
<li>After all test packages execute, a screenshot is taken and saved to
<code>out/host/linux-x86/afw-th/android-cts/repository/logs/<em>start-time</em></code>
as: <code>screenshot-<em>random_number</em>.png</code>.
This information is also logged in the host log.</li>
</ul>
</li>
</ul>

<h2 id=faq>FAQ</h2>
<p>For help with questions not answered below, contact
<a href="mailto:afw-testharness-support@google.com">afw-testharness-support@google.com</a>.
</p>

<p><strong>Can I run test plan <code>afw-userdebug-build</code> on a device
flashed with user build?</strong></p>
<p><em>No. Test packages in the <code>afw-userdebug-build</code> plan factory
reset the testing device before running the actual test flow and require
<code>adb</code> debugging to be auto-enabled. With a user build,
<code>adb</code> debugging can be enabled only by manually changing the
setting in Developer options.</em></p>

<p><strong>Can I run test plan <code>afw-user-build</code> on a device flashed
with userdebug build?</strong></p>
<p><em>Yes, but we recommend that you run this test plan on a user build.</em></p>

<p><strong>Sometimes my test fails because UI loading takes too much time. How
can I fix this?</strong></p><em>Configure the <code>timeout_size</code> setting
in <code>./android-cts/repository/testcases/afw-test.props</code>. Valid
settings are: S, M, L, XL, XXL.</em></p>

<p><strong>The test package
<code>com.android.afwtest.NfcProvisioning</code> (or
<code>SuwDoProvisioning</code>) fails on my device because the installed initial
setup (i.e. Setup Wizard) shows customized UI (such as Term &amp; Conditions)
after provisioning is complete. How can I skip this customized UI?</strong></p>
<p><em>There should be minimal UI after the provisioning process. The test
harness will automatically skip such UI if the UI has a button that has
meaningful text or content description that contains any of the following words:
Skip, Finish, Done, Accept, Agree, Next, Continue, or Proceed. Alternatively,
you can define a button in <code>afw-test.props</code> to configure the test
harness to skip your UI. Example:</em></p>
<pre>
oem_widgets=your_btn
your_btn.text=your_customized_text
your_btn.package=your_package
your_btn.action=click
</pre>
<em><p>To define multiple widgets, separate using commas.</em></p>

<p><strong>The test package
<code>com.android.afwtest.NfcProvisioning</code> (or
<code>SuwDoProvisioning</code>) failed and the last UI screen is "Verify your
account." Why does this happen and how can I recover the testing device?
</strong></p>
<p><em>This failure occurs because the previous test package failed to clear
Factory Reset Protection at the end of the test. You must manually enter the
account to unlock the device.</em></p>

<p><strong>My device needs more time to factory reset. Can I extend the factory
reset timeout?</strong></p>
<p><em>Yes. Configure the <code>factory_reset_timeout_min</code> setting in
<code>afw-test.props</code>. Valid settings are in minutes; you can set to any
number of minutes that works with your device.</em></p>
