<p>You can deploy the execution service and test binaries anywhere in the target
file system; however, test binaries expect to find data directories in the
current working directory. When ready, start the Test Execution Service on the
target device. For details on starting the service, see
<a href="/devices/graphics/port-tests.html#test_execution_service">Test
execution service</a>.</p>
<h2 id=command_line_arguments>Command line arguments</h2>

test programs.</p>

</tr>
<tr>
<td><code>--deqp-case=<casename></code></td>
<td>Run cases that match a given pattern. Wildcard (*) is supported.</td>

service will set the filename when starting a test.</td>
</tr>
<tr>
<td><code>--deqp-stdin-caselist<br/>
--deqp-caselist=<caselist><br/>

the EGL context.</td>

platform-dependent. On the EGL platform, this is the EGL configuration ID.</td>
</tr>
<tr>

<td><p>Run tests for a named GL configuration. Interpretation is
platform-dependent. For EGL, the format is
<code>rgb(a)<bits>d<bits>s<bits></code>. For example, a
value of <code>rgb888s8</code> will select the first configuration where the
color buffer is RGB888 and the stencil buffer has 8 bits.</td>
</tr>

<td><code>--deqp-gl-context-flags=<flags></code></td>
<td>Creates a context. Specify <code>robust</code> or <code>debug</code>.</td>
</tr>

<td>Try to create a surface with a given size. Support for this is optional.</td>
</tr>
<tr>

<td>Use a given surface type as the main test rendering target. Possible
types are <code>window</code>, <code>pixmap</code>, <code>pbuffer</code>,
and <code>fbo</code>.</td>
</tr>
<tr>
<td><code>--deqp-screen-rotation=<rotation></code></td>
<td>Screen orientation in increments of 90 degrees for platforms that
support it.</td>
</tr>
</table>
<h3 id=test_case_list_format>Test case list format</h3>
<p>The test case list can be given in two formats. The first option is to list
the full name of each test on a separate line in a standard ASCII file. As the
test sets grow, the repetitive prefixes can be cumbersome. To avoid repeating
the prefixes, use a trie (also known as a prefix tree) syntax shown below.</p>
<pre>
{nodeName{firstChild{…},…lastChild{…}}}
</pre>
<p>For example:</p>
<pre>
{dEQP-EGL{config-list,create_context{rgb565_depth_stencil}}}
</pre>
<p>Translates into the following two test cases:</p>
<pre>
dEQP-EGL.config_list
dEQP-EGL.create_context.rgb565_depth_stencil
</pre>
<h2 id=android>Android</h2>
<p>The Android application package contains all required components, including
the test execution service, test binaries, and data files. The test activity is
a <code>NativeActivity</code> that uses EGL (requires Android 3.2 or higher).</p>
<p>The application package can be installed with the following command (name
shown is the name of the APK in the Android CTS package; which name depends on
the build):</p>
<pre>$ adb –d install –r com.drawelements.deqp.apk</pre>
<p>To launch the test execution service and to setup port forwarding, use the
following:</p>
<pre>
$ adb –d forward tcp:50016 tcp:50016
$ adb –d shell am start –n com.drawelements.deqp/.execserver.ServiceStarter
</pre>
<p>Debug prints can be enabled by executing the following before starting the
tests:</p>
<pre>
$ adb –d shell setprop log.tag.dEQP DEBUG
</pre>
<h3 id=executing_tests_on_android_without_android_cts>Executing tests on
Android without Android CTS</h3>
<p>To manually start the test execution activity, construct an Android intent
that targets <code>android.app.NativeActivity</code>. The activities can be
found in the <code>com.drawelements.deqp</code> package. The command line must
be supplied as an extra string with key <code>"cmdLine"</code> in the Intent.</p>
<p>A test log is written to <code>/sdcard/dEQP-log.qpa</code>. If the test run
does not start normally, additional debug information is available in the device
log.</p>
<p>You can launch an activity from the command line using the <code>am</code>
utility. For example, to run <code>dEQP-GLES2.info</code> tests on a platform
supporting <code>NativeActivity,</code> use the following commands.</p>
<pre>$ adb -d shell am start -n com.drawelements.deqp/android.app.NativeActivity -e \
cmdLine "deqp --deqp-case=dEQP-GLES2.info.* --deqp-log-filename=/sdcard/dEQP-Log.qpa
</pre>
<h3 id=debugging_on_android>Debugging on Android</h3>
<p>To run the tests under the GDB debugger on Android, first compile and install
the debug build by running the following two scripts:</p>
<pre>
$ python android/scripts/build.py --native-build-type=Debug
$ python android/scripts/install.py
</pre>
<p>After the debug build is installed on the device, to launch the tests under
GDB running on the host, run the following command:</p>
<pre>$ python android/scripts/debug.py \
--deqp-commandline="--deqp-log-filename=/sdcard/TestLog.qpa --deqp-case=dEQP-GLES2.functional.*"
</pre>
<p>The deqp command line depends on the test cases to be executed and other
required parameters. The script adds a default breakpoint at the beginning of
the deqp execution (<code>tcu::App::App</code>).</p>
<p>The <code>debug.py</code> script accepts multiple command line arguments for
actions such as setting breakpoints for debugging, gdbserver connection
parameters, and paths to additional binaries to debug (use <code>debug.py
--help</code> for all arguments and explanations). The script also copies some
default libraries from the target device to get symbol listings.</p>
<p>To step through driver code (such as when the GDB needs to know the locations
of the binaries with full debug information), add more libraries via
<code>debug.py</code> command line parameters. This script writes out a
configuration file for the GDB starting from line 132 of the script file. You
can provide additional paths to binaries, etc., but supplying correct command
line parameters should be enough.</p>
<p class="note"><strong>Note:</strong> On Windows, the GDB binary requires
<code>libpython2.7.dll</code>. Before launching <code>debug.py</code>, add
<code><path-to-ndk>/prebuilt/windows/bin</code> to the PATH variable.</p>
<p class="note"><strong>Note:</strong> Native code debugging does not work on
stock Android 4.3; for workarounds, refer to
<a href="https://code.google.com/p/android/issues/detail?id=58373">https://code.google.com/p/android/issues/detail?id=58373</a>.
Android 4.4 and higher do not contain this bug.</p>
