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.

Introduction
This document contains instructions for certifying conformance of implementations of the OpenGL and OpenGL ES APIs. The steps of the process are as follows:
- Configure the conformance tests and port them to your platform.
- Build a test executable and run it against your implementation to produce result logs.
- Debug any test failures and modify your implementation as needed until it passes the test.
- Create a Submission Package containing your final result logs and other documents describing the tested platform.
- 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).
Configuration
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:
Name | Description |
---|---|
android | Used in Android build. Requires use of suitable toolchain file (see cmake/ directory) |
default | Checks for presence of GL, ES2, ES3, and EGL libraries and headers in default search paths and configures build accordingly |
null | Null build target |
nullws | NullWS build target |
x11_egl | X11 build for platforms with native EGL support |
x11_glx | X11 build for platforms with native GLX support |
x11_egl_glx | X11 build for platforms with native EGL/GLX support |
Example target file (targets/null/null.cmake):
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:
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:
For OpenGL CTS releases, and OpenGL ES CTS releases prior to opengl-es-cts-3.2.4.0 download Khronos Confidential Conformance Test Suite:
For OpenGL CTS releases, and OpenGL ES CTS releases prior to opengl-es-cts-3.2.4.0 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-3.2.4.0 Khronos Confidential CTS is mandatory if you plan to make a conformance submission (see Creating a Submission Package). For opengl-es-cts-3.2.4.0 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.
Windows
Requirements:
- Visual Studio (2015 or newer recommended) or Windows SDK
- CMake 2.8.x 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:
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.:
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.
Linux
Required tools:
- Standard build utilities (make, gcc, etc.)
- CMake 2.8.x
- Necessary API libraries (OpenGL, GLES, EGL depending on configuration)
Building ES2 or ES3.x conformance tests:
Building OpenGL conformance tests:
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.
Android
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:
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.:
Available values for --kc-cts-target
are gles32
, gles31
, gles3
, gles2
and gl
.
The package can be installed by either running:
By default the CTS package will contain libdeqp.so 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:
Porting
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:
- Changes to the make system used to generate the test executable.
- Changes needed to adapt the test executable to the operating system used on the platform.
- 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 Porting Changes
Other than changes needed for porting, the only changes that are permitted are changes to fix bugs in the conformance test. 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. Changes required to address either of these issues typically require waivers.
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:
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:
Conformance run for OpenGL 3.0 - 4.6 on Windows:
Full list of parameters for the cts-runner
binary:
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.
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.
Android
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:
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:
Conformance run configuration can be generated by supplying a summary
= 'true'
string extra. See the following example:
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. Blackweb keyboard download.
Individual tests can be launched as well by targeting org.khronos.gl_cts/android.app.NativeActivity
activity. Command line arguments must be supplied in a cmdLine
string extra. See following example:
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 above 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:
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:
To list available test cases (writes out *-cases.txt
files per module), run:
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
.
Command line options
Full list of parameters for the glcts
binary:
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:
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.
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
Opengl Es2 0 Download Torrent
external/openglcts/scripts/verify_submission.py
: Script that verifies logs based oncts-run-summary.xml
file.scripts/log/log_to_csv.py
: This utility converts.qpa
log into CSV format. This is useful for importing results into other systems.scripts/log/log_to_xml.py
: 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 127.0.0.1:8000
.
Parser for the .qpa
log file format in python is provided in scripts/log/log_parser.py
.
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 log_to_xml.py
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.
Waivers
The procedure for requesting a waiver is to report the issue by filing a bug report in the Gitlab VK GL CTS project (https://gitlab.khronos.org/Tracker/vk-gl-cts). 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.

Troubleshooting
Opengl_es_2_0_emulator Winxp Vm.n.exe Download
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.
