This page provides instructions for running deqp tests in Linux and Windows environments, using command line arguments, and working with the Android application package.
Linux and Windows environments
Start by copying the following files and directories to the target.
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 Test execution service.
Command line arguments
The following table lists command line arguments that affect execution of all test programs.
||Run cases that match a given pattern. Wildcard (*) is supported.|
||Write test results to the file whose name you provide. The test execution service will set the filename when starting a test.|
||Read case list from stdin or from a given argument. The test execution service will set the argument according to the execution request received. See the next section for a description of the case list format.|
||Override iteration count for tests that support a variable number of iterations.|
||Base seed for the test cases that use randomization.|
GLES2 and GLES3-specific argumentsThe following table lists the GLES2- and GLES3-specific arguments.
||OpenGL context type. Available context types depend on the platform. On
platforms supporting EGL, the value
||Run tests for the provided GL configuration ID. Interpretation is platform-dependent. On the EGL platform, this is the EGL configuration ID.|
Run tests for a named GL configuration. Interpretation is
platform-dependent. For EGL, the format is
||Creates a context. Specify
||Try to create a surface with a given size. Support for this is optional.|
||Use a given surface type as the main test rendering target. Possible
||Screen orientation in increments of 90 degrees for platforms that support it.|
Test case list format
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.
Translates into the following two test cases:
The Android application package contains all required components, including
the test execution service, test binaries, and data files. The test activity is
NativeActivity that uses EGL (requires Android 3.2 or higher).
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):
adb –d install –r com.drawelements.deqp.apk
To launch the test execution service and to setup port forwarding, use the following:
adb –d forward tcp:50016 tcp:50016
adb –d shell am start –n com.drawelements.deqp/.execserver.ServiceStarter
Debug prints can be enabled by executing the following before starting the tests:
adb –d shell setprop log.tag.dEQP DEBUG
Executing tests on Android without Android CTS
To manually start the test execution activity, construct an Android intent
android.app.NativeActivity. The activities can be
found in the
com.drawelements.deqp package. The command line must
be supplied as an extra string with key
"cmdLine" in the Intent.
A test log is written to
/sdcard/dEQP-log.qpa. If the test run
does not start normally, additional debug information is available in the device
You can launch an activity from the command line using the
utility. For example, to run
dEQP-GLES2.info tests on a platform
NativeActivity, use the following commands.
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
Debugging on Android
To run the tests under the GDB debugger on Android, first compile and install the debug build by running the following two scripts:
python android/scripts/build.py --native-build-type=Debug
After the debug build is installed on the device, to launch the tests under GDB running on the host, run the following command:
python android/scripts/debug.py \ --deqp-commandline="--deqp-log-filename=/sdcard/TestLog.qpa --deqp-case=dEQP-GLES2.functional.*"
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 (
debug.py 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
--help for all arguments and explanations). The script also copies some
default libraries from the target device to get symbol listings.
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
debug.py 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.
Note: On Windows, the GDB binary requires
libpython2.7.dll. Before launching
<path-to-ndk>/prebuilt/windows/bin to the PATH variable.
Note: Native code debugging does not work on stock Android 4.3; for workarounds, refer to this public bug. Android 4.4 and higher do not contain this bug.
