OpenGL and OpenGL ES 2.0/3.X Conformance Test Instructions

This document describes how to build, port, and run the OpenGL and OpenGL ES 2.0/3.X conformance tests, and how to verify and submit test results.

The Conformance Tests are built on dEQP framework. dEQP documentation is available at


Test History

The OpenGL and OpenGL ES Conformance Tests are expanded versions of the OpenGL ES 2.x Conformance Test. Much of the development was done by Symbio, Inc. under a contract with The Khronos Group. drawElements donated a considerable number of new tests and a new execution framework for version 1.1. The tests are built from the same source code base, although some individual feature tests are specific to OpenGL or OpenGL ES and their specification versions, and compilation options differing between OpenGL and OpenGL ES affect how the tests are compiled and executed in some cases.


This document contains instructions for certifying conformance of implementations of the OpenGL and OpenGL ES APIs. The steps of the process are as follows:

  1. Configure the conformance tests and port them to your platform.
  2. Build a test executable and run it against your implementation to produce result logs.
  3. Debug any test failures and modify your implementation as needed until it passes the test.
  4. Create a Submission Package containing your final result logs and other documents describing the tested platform.
  5. Submit the results to the appropriate Review Committee via the Khronos Adopters web page. The Committee will examine your submission and will notify you within thirty days if they find any issues requiring action on your part.

This document describes each of these steps in detail. It also provides advice on reproducing, understanding, and debugging test failures, and discusses how to extend or modify the tests and the test framework.

The reader is assumed to be a fluent programmer experienced with command line utilities and build tools, such as CMake or Make.

Test Environment Requirements

The conformance tests require a file system. The file system requires support for long file names (i.e. > 8.3 name format). Source files in the conformance tests use mixed case file names. When the --verbose option is used, rendered images and test case shaders are copied to the log files. This can lead to quite large log files, up to hundreds of megabytes on disk.

Each execution of the conformance test writes a text-format results log to a disk. You will need to include this log as part of your conformance submission package.

The conformance test executable can be large. Compiler options and CPU instruction sets can cause substantial variation. The disk space required for the build including all the temporary files can be up to 400MB.

The build environment is expected to support C++ with exceptions and the Standard Template Library (STL).

Configuring and Building the Tests

The CTS is built via CMake build system. The requirements for the build are as follows:

  • CMake 3.0 (3.6 for Android NDK r17+ builds) or newer
  • C++ compiler with STL and exceptions support
  • Unix: Make + GCC / Clang
  • Windows: Visual Studio or Windows SDK (available free-of-charge)
  • Android: Android SDK and NDK for host platform

The build is controlled by the file CMakeLists.txt found at the root of the CTS source.

If the platform and compiler tools you use are not supported, you may be able to add support for that platform and tools to the build system. If you do this, please submit your changes back to Khronos for inclusion in the official tests going forward.

Otherwise, if you choose not to use the supplied Makefiles, you must construct an equivalent build system for the chosen development environment(s).


The build is configured by using CMakeLists.txt files in the build target directory (targets/). They specify platform-specific configuration, including include paths and link libraries.

The main CMakeLists.txt includes the target file based on the DEQP_TARGET variable. For example -DDEQP_TARGET=my_target will use the target description file targets/my_target/my_target.cmake.

See the main CMakeLists.txt file for the description of the variables that the target file can set.

Porting to a new platform includes either creating a new target file, or modifying an existing target description.

NOTE: All paths, except TCUTIL_PLATFORM_SRCS are relative to root source directory. TCUTIL_PLATFORM_SRCS is relative to framework/platform directory.

Following target files are provided with the package:

androidUsed in Android build. Requires use of suitable toolchain file (see cmake/ directory)
defaultChecks for presence of GL, ES2, ES3, and EGL libraries and headers in default search paths and configures build accordingly
nullNull build target
nullwsNullWS build target
x11_eglX11 build for platforms with native EGL support
x11_glxX11 build for platforms with native GLX support
x11_egl_glxX11 build for platforms with native EGL/GLX support

Example target file (targets/null/null.cmake):

message("*** Using null context target")



Common configuration variables and their default values in CMake syntax:

  • Target name
  • List of link libraries per API. If no libraries are specified, entry points are loaded at run-time by default for OpenGL ES APIs. EGL always requires link libraries. OpenGL always uses run-time loading.
  • Generic platform libraries required to link a working OpenGL (ES) Application (e.g. X11 libraries on Unix/X11)
  • Libraries / binaries that need to be copied to the build target dir
  • If running on Linux using X11 for creating windows etc., enable this.
  • Embed the test files in the test Before building with this set (if GTF module is present), run these commands:
cd external/kc-cts/src/GTF_ES/glsl/GTF

In your target .cmake file add


Building the Tests

To build the framework, you need first to download sources for zlib, libpng, glslang, spirv-headers, and spirv-tools.

To download sources, run:

python external/

For OpenGL CTS releases, and OpenGL ES CTS releases prior to opengl-es-cts- download Khronos Confidential Conformance Test Suite:

python external/

For OpenGL CTS releases, and OpenGL ES CTS releases prior to opengl-es-cts- the results for the tests included in this suite must be included in a conformance submission.

NOTE: You need to be a Khronos Adopter and have an active account at Khronos Gitlab to be able to download Khronos Confidential CTS. It is possible to run and build the CTS without the Khronos Confidential CTS. For OpenGL CTS releases, and OpenGL ES CTS releases prior to opengl-es-cts- Khronos Confidential CTS is mandatory if you plan to make a conformance submission (see Creating a Submission Package). For opengl-es-cts- and later OpenGL ES CTS releases Khronos Confidential CTS results must not be included in a submission package.

With CMake out-of-source builds are always recommended. Create a build directory of your choosing, and in that directory generate Makefiles or IDE project using Cmake.



  • Visual Studio (2015 or newer recommended) or Windows SDK
  • CMake 3.10.2 Windows native version (i.e. not Cygwin version)
  • For GL/ES2/ES3.x tests: OpengGL, OpenGL ES 2 or ES 3.x libraries and headers

To choose the backend build system for CMake, choose one of the following Generator Names for the command line examples in the next steps:

  • VS2015: “Visual Studio 14”
  • NMake (must be run in VS or SDK command prompt): “NMake Makefiles”

Building GL, ES2, or ES3.x conformance tests:

cmake <path to openglcts> -DDEQP_TARGET=default -G"<Generator Name>"
cmake --build .

Khronos Confidential CTS doesn't support run-time selection of API context. If you intend to run it you need to additionally supply GLCTS_GTF_TARGET option to you cmake command, e.g.:

cmake <path to openglcts> -DDEQP_TARGET=default -DGLCTS_GTF_TARGET=<target> -G"<Generator Name>"

Available <target>s are gles2, gles3, gles31, gles32, and gl. The default <target> is gles32.

It's also possible to build GL-CTS.sln in Visual Studio instead of running the cmake --build . command.

NOTE: Do not create the build directory under the source directory (i.e anywhere under <path to openglcts>) on Windows, since it causes random build failures when copying data files around.

NOTE: You can use the CMake for Windows GUI to do configuration and project file generation.

NOTE: If using cygwin, you must install and ensure you use the Windows version of cmake. The cygwin vesion does not contain the Visual Studio generators. Here is a shell function you can put in your cygwin .bash_profile to use it easily. With this you can simply type wcmake to run the Windows version.

function wcmake () {
    (TMP=$tmp TEMP=$temp; unset tmp; unset temp; "C:/Program Files (x86)/CMake 2.8/bin/cmake" "$@")


Required tools:

  • Standard build utilities (make, gcc, etc.)
  • CMake 3.10.2
  • Necessary API libraries (OpenGL, GLES, EGL depending on configuration)

Building ES2 or ES3.x conformance tests:

cmake <path to openglcts> -DDEQP_TARGET=null -DGLCTS_GTF_TARGET=gles32
cmake --build .

Building OpenGL conformance tests:

cmake <path to openglcts> -DDEQP_TARGET=null -DGLCTS_GTF_TARGET=gl
cmake --build .

Khronos Confidential CTS doesn't support run-time selection of API context. If you intend to run it then the GLCTS_GTF_TARGET option is necessary.

Available values for GLCTS_GTF_TARGET are gles2, gles3, gles31, gles32, and gl. The default value is gles32.

CMake chooses to generate Makefiles by default. Other generators can be used as well. See CMake help for more details.


The conformance tests come with native Android support. The following packages are needed in order to build an Android binary:

  • Python 3.x (for the build related scripts, some other scripts still use Python 2.7.x)
  • Android NDK r17c
  • Android SDK with API 28 packages and tools installed
  • Apache Ant

An Android binary (for ES 3.2) can be built using command:

python scripts/android/ --target=openglcts --sdk <path to Android SDK> --ndk <path to Android NDK>

By default the CTS package will be built for the Android API level 28. Another API level may be supplied using --native-api command line option.

If Khronos Confidential CTS is present then the script will set GLCTS_GTF_TARGET to gles32 by default. It is possible to specify a different GLCTS_GTF_TARGET target by invoking the script with the --kc-cts-target option, e.g.:

python scripts/android/ --target=openglcts --kc-cts-target=gles31 --sdk <path to Android SDK> --ndk <path to Android NDK>

Available values for --kc-cts-target are gles32, gles31, gles3, gles2 and gl.

The package can be installed by either running:

python scripts/android/ --target=openglcts

By default the CTS package will contain built for armeabi-v7a, arm64-v8a, x86, and x86_64 ABIs, but that can be changed with --abis command line option.

To pick which ABI to use at install time, following commands must be used instead:

adb install --abi <ABI name> <build root>/Khronos-CTS.apk /data/local/tmp/Khronos-CTS.apk


The Conformance Tests have been designed to be relatively platform-, OS-, and compiler-independent. Adopters are responsible for final changes needed to allow the Test to run on the platform they wish to certify as conformant.

Common Porting Changes

Porting the dEQP framework requires implementation of either glu::Platform or, on platforms supporting EGL, the tcu::EglPlatform interface. The porting layer API is described in detail in following files:


This version of the dEQP framework includes ports for Windows (both EGL and WGL), X11 (EGL and XGL), and Android.

Base portability libraries in framework/delibs seldom need changes. However, introducing support for a new compiler or a new processor family may require some changes to correctly detect and parameterize the environment.

Porting typically involves three types of changes:

  1. Changes to the make system used to generate the test executable.
  2. Changes needed to adapt the test executable to the operating system used on the platform.
  3. Changes to the platform specific GL and EGL header files.

Changes should normally be confined to build files (CMake or Python) or source files (.c, .h, .cpp, and .h files) in the following directories or their subdirectories:

  • framework/platform
  • targets

If you find that you must change other source (.c, .cpp, .h, or .hpp) files, you will need to file a waiver as described below.

Note that the conformance tests assume that the implementation supports EGL. However EGL is not required for OpenGL or OpenGL ES conformance.

Most of the tests require at least 256x256 pixels resolution in order to run properly and produce stable results. It is, therefore, important to ensure that a port to a new platform can support surfaces that fulfill width and height requirements.

Other Allowable Changes

Changes to fix bugs in the conformance test are allowed. A bug in the conformance test is a behavior which causes clearly incorrect execution (e.g., hanging, crashing, or memory corruption), OR which requires behavior which contradicts or exceeds the requirements of the relevant OpenGL or OpenGL ES Specification. Before being used for a submission, bugfixes must be accepted and merged into the CTS repository. git cherry-pick is strongly recommended as a method of applying bug fixes.

Other changes must be accompanied by a waiver.

NOTE: When cherry-picking patches on top of release tag, please use git cherry-pick -x to include original commit hash in the commit message.

Running the Tests

All the following commands need to be run in the CTS build directory. If you need to move the binaries from the build directory, remember to copy the data directories named gl_cts, gles2, gles3, and gles31 and its subdirectories from the build directory to the test target in the same relative locations.

If the build instructions have been followed as-is, the correct path is:

cd <builddir>/external/openglcts/modules

Conformance runs

A conformance run can be launched either by running the cts-runner binary with appropriate options on Linux/Windows or by running an Android application.

Linux and Windows

Conformance run for OpenGL ES 3.2 on Windows:

Debug/cts-runner.exe --type=es32
  [For ES 3.1 use --type=es31; ES 3.0 use --type=es3; for ES 2.0, use --type=es2]

Conformance run for OpenGL 3.0 - 4.6 on Windows:

Debug/cts-runner.exe --type=glxy
  [x and y are the major and minor specifiction versions]

Full list of parameters for the cts-runner binary:

--type=[esN[M]|glNM] Conformance test run type. Choose from
					 ES: es2, es3, es31, es32
					 GL: gl30, gl31, gl32, gl33, gl40, gl41, gl42, gl43, gl44, gl45, gl46
--waivers=[path]     Path to xml file containing waived tests
--logdir=[path]      Destination directory for log files
--summary            Print summary without running the tests
--verbose            Print out and log more information

The conformance run will create one or more .qpa files per tested config, a summary .qpa file containing run results and a summary .xml file containing command line options for each run, all of which should be included in your conformance submission package. The final verdict will be printed out at the end of run.

Sometimes it is useful to know the command line options used for the conformance before the run completed. Full conformance run configuration is written to cts-run-summary.xml and this file can be generated by adding --summary parameter.

By default the cts-runner does not include result images or shaders used in the logs. Adding parameter --verbose will cause them to be included in the logs. Images will be embedded as PNG data into the.qpa log files. See Section Test Logs for instructions on how to view the images.

To direct logs to a directory, add --logdir=[path] parameter.

To specify waived tests, add --waivers=[path] parameter.

NOTE: Due to the lack of support for run-time selection of API context in the Khronos Confidential CTS, a conformance run may fail if it is executed for an API version that doesn't match the GLCTS_GTF_TARGET value used during the build step.


Once the CTS binary is built and installed on the device, a new application called ES3.2 CTS, ES3.1 CTS, ES3 CTS, ES2 CTS, GL4.5 CTS, or GL4.6 CTS (depending on the test version you built) should appear in the launcher. Conformance test runs can be done by launching the applications.

Alternatively it is possible to start a conformance run from the command line, for example to launch a GLES 3.2 conformance run use:

am start -n org.khronos.gl_cts/org.khronos.cts.ES32Activity -e logdir "/sdcard/logs"

For GLES 2.0, GLES 3.0, GLES 3.1, GL 4.5, or GL 4.6 conformance runs, substitute the following activity name (respectively) ES2Activity, ES3Activity, ES31Activity, GL45Activity, or GL46Activity.

Test logs will be written to /sdcard by default. The log path can be customized by supplying a logdir string extra in launch intent. Verbose mode can be enabled by supplying a verbose = "true" string extra. See the following example:

am start -n org.khronos.gl_cts/org.khronos.cts.ES32Activity -e logdir "/sdcard/logs" -e verbose "true"

Conformance run configuration can be generated by supplying a summary = "true" string extra. See the following example:

am start -n org.khronos.gl_cts/org.khronos.cts.ES32Activity -e logdir "/sdcard/logs" -e summary "true"

Waivers can be specified by supplying a waivers string extra. See the following example:

am start -n org.khronos.gl_cts/org.khronos.cts.ES32Activity -e logdir "/sdcard/logs" -e waivers "/sdcard/waivers.xml"

NOTE: Supplying a summary = "true" string extra will result in the cts-run-summary.xml file being written out but no tests will be executed.

Individual tests can be launched as well by targeting org.khronos.gl_cts/ activity. Command line arguments must be supplied in a cmdLine string extra. See following example:

am start -n org.khronos.gl_cts/ -e cmdLine "cts --deqp-gl-config-id=1 --deqp-log-filename=/sdcard/ES32-egl-config-1.qpa --deqp-surface-width=128 --deqp-surface-height=128"

In addition to the detailed *.qpa output files, the Android port of the CTS logs a summary of the test run, including the pass/fail status of each test. This summary can be viewed using the Android logcat utility.

See Section Running Subsets below for details on command line parameters.

Running Subsets

Run shader compiler loop test cases from the OpenGL ES 3.0 CTS using EGL config with ID 3:

Debug/glcts.exe --deqp-case=KHR-GLES3.shaders.loops.* --deqp-gl-config-id=3

Note that the GL context version is determined by the case name. KHR-GLES3 in the example above selects OpenGL ES 3.0. The command to run the same test against OpenGL version 4.1 is:

Debug/glcts.exe --deqp-case=GL41-CTS.shaders.loops.* --deqp-gl-config-id=3

To list available test cases (writes out *-cases.txt files per module), run:

Debug/glcts.exe --deqp-runmode=txt-caselist

The type of the run for cts-runner chooses a specific list of test cases to be run. The selected tests can be checked from the summary logs. To run the same tests, just give equivalent test selection parameters to the glcts.

Understanding the Results

At the end of a completed test run, a file called cts-run-summary.xml is generated. It will contain summaries per configuration and the full command lines for the glcts application (See Section Running Subsets) for debugging purposes. Additionally, a summary string similar to one below is printed:

4/4 sessions passed, conformance test PASSED

If the run fails, the message will say FAILED instead of PASSED. Under Linux or Windows, this string is printed to stdout if available. Under Android, it is emitted to the Android logging system for access via logcat.

Each test case will be logged into the .qpa files in XML. Below is a minimal example of a test case log. The Result element contains the final verdict in the StatusCode attribute. Passing cases will have Pass and failing cases Fail. Other results such as QualityWarning, CompatibilityWarning, NotSupported or ResourceError are possible. Only Fail status will count as failure for conformance purposes.

<TestCaseResult Version="0.3.2" CasePath="" CaseType="SelfValidate">
    <Text>Vendor A</Text>
    <Result StatusCode="Pass">Pass</Result>

If the failure count is zero for all config sequences, the implementation passes the test. Note that in addition to a successful test result, a Submission Package must satisfy the conditions specified below under Passing Criteria in order to achieve conformance certification.

Test Logs

The CTS writes test logs in XML encapsulated in a simple plain-text container format. Each tested configuration listed in cts-run-summary.xml

To analyse and process the log files, run the following scripts

  • located in VK-GL-CTS-Tools: Script that verifies logs based on cts-run-summary.xml file.
  • scripts/log/ This utility converts .qpa log into CSV format. This is useful for importing results into other systems.
  • scripts/log/ Converts .qpa into well-formed XML document. The document can be then viewed in browser using the testlog.{xsl,css} files.

Some browsers, like Chrome, limit local file access. In such case, the files must be accessed over HTTP. Python comes with a simple HTTP server suitable for the purpose. Run python -m SimpleHTTPServer in the directory containing the generated XML files and point the browser to

Parser for the .qpa log file format in python is provided in scripts/log/

Python scripts require python 2.7 or newer in 2.x series. They are not compatible with python 3.x.

Debugging Test Failures

The best first step is to run the failing test cases via glcts executable to get the more verbose logs. Use, for example, the script detailed in Section Test Logs, to view the generated logs. If the visual inspection of the logs does not give sufficient hints on the nature of the issue, inspecting the test code and stepping through it in debugger should help.


The procedure for requesting a waiver is to report the issue by filing a bug report in the Gitlab VK GL CTS project ( When you create your submission package, include references to the waivers as described in the adopters' agreement. Fully-qualified links to bug reports are highly recommended. Including as much information as possible in your bug report will ensure the issue can be progressed as speedily as possible. Such bug report must include a link to suggested file changes. Issues must be labeled Waiver and OpenGL-ES (for OpenGL ES submissions) or Waiver and OpenGL (for OpenGL submissions) and identify the CTS release tag and affected tests.

Creating a Submission Package

Please see the Creating a Submission Package page.

Submission Update Package

Please see the Submission Update Package page.

Passing Criteria

Please see the Conformance Submission Passing Criteria page.


Crashes early on in the run

If using run-time entry point loading, it is possible that not all required entry points are available. This will result in NULL pointer dereferencing.

Build fails

First try re-running the build. If that does not help and you have used the same build directory with different version of the CTS, remove the build directory and run the CMake again.
