FATE provides a regression test suite embedded within the Libav build system. It can be run locally and optionally configured to send reports to a web aggregator and viewer http://fate.libav.org.
It is advised to run FATE before submitting patches to the current codebase and provide new tests when submitting patches to add additional features.
In order to run, FATE needs a large amount of data (samples and references) that is provided separately from the actual source distribution.
To inform the build system about the test suite location, pass
‘--samples=<path to the samples>’ to
configure or set the
SAMPLES Make variable or the LIBAV_SAMPLES environment variable
to a suitable value.
To use a custom wrapper to run the test, pass ‘--target-exec’ to
configure or set the TARGET_EXEC Make variable.
The dataset is available through
rsync, is possible to fetch
the current sample using the straight rsync command or through a specific
# rsync -aL rsync://fate-suite.libav.org/fate-suite/ fate-suite
# make fate-rsync SAMPLES=fate-suite
FATE regression test can be run through
Specific Makefile targets and Makefile variables are available:
List all fate/regression test targets.
Shortcut to download the fate test samples to the specified test suite location.
Run the FATE test suite (requires the fate-suite dataset).
Verbosity level, can be set to 0, 1 or 2.
show just the test arguments
show just the command used in the test
Specify or override the path to the FATE samples at make time, it has a meaning only while running the regression tests.
Specify how many threads to use while running regression tests, it is quite useful to detect thread-related regressions.
Specify which threading strategy test, either slice or frame, by default slice+frame
Specify a mask to be applied to autodetected CPU flags.
Specify or override the wrapper used to run the tests.
Set to 1 to generate the missing or mismatched references.
make V=1 SAMPLES=/var/fate/samples THREADS=2 CPUFLAGS=mmx fate
In order to automatically testing specific configurations, e.g. multiple
tests/fate.sh is provided.
This shell script builds Libav, runs the regression tests and prepares a report that can be sent to http://fate.libav.org/ or directly examined locally.
The configuration file passed to
fate.sh is shell scripts as well.
It must provide at least a slot identifier, the repo from which fetch the sources, the samples directory, a workdir with enough space to build and run all the tests. Optional submit command fate_recv and a comment to describe the testing profile are available.
Additional optional parameter to tune the Libav building and reporting process can be passed.

The TARGET_EXEC option provides a way to run FATE wrapped in
wine or on remote targets
In order to send reports you need to create an
ssh key and send it
