<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, please review the following:</p>

<pre>
{dEQP-EGL{config-list,create_context{rgb565_depth_stencil}}}
</pre>

<p>That list would translate into 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 everything required, including the
test execution service, test binaries, and data files. The test activity is a <code>NativeActivity </code>and it uses EGL, which requires Android 3.2 or later.</p>

<p>The application package can be installed with the following command. The name shown is the name of the APK in the Android CTS package. The 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>If you want 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 will be 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>The activity can be launched 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> the following command can be used:</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 will depend on test cases to be executed and other
required parameters. The script will add a default breakpoint into the
beginning of the deqp execution (<code>tcu::App::App</code>).</p>

<p>The <code>debug.py </code>script accepts multiple command line arguments, e.g. for the following:</p>

<ul>
  <li> Setting the breakpoints for debugging
  <li> gdbserver connection parameters
  <li> Paths to additional binaries to debug  
</ul>

<p>Running <code>debug.py --help</code> will list all command line parameters, with explanations.</p>

<p>The script copies some default libraries from the target device to get symbol
listings. </p>

<p>If there is a need to step through driver code, more libraries can be added via <code>debug.py</code> command line parameters. This would be applicable, for
example, if the GDB needs to know the locations of the binaries with full debug
information. The <code>debug.py</code> script writes out a configuration file for the GDB starting from line 132 of
the script file. Additional paths to binaries, etc., can be added there, but
supplying correct command line parameters should be enough.</p>

<p><strong>Notes:</strong></p>

<ul>
  <li> On Windows, the gdb binary requires <code>libpython2.7.dll</code>. Add
<code>&lt;path to ndk&gt;/prebuilt/windows/bin</code> to the PATH variable before launching <code>debug.py</code>.
  <li> Native code debugging does not work on stock Android 4.3. See the Android bug
report below for suggested workarounds. The bug has been fixed in Android 4.4;
see the following: <a href="https://code.google.com/p/android/issues/detail?id=58373">https://code.google.com/p/android/issues/detail?id=58373</a>
