This can be useful to filter out noise in known-broken scenarios like miscompilation by legacy compilers and similar. Originally based on a patch by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de>

@chapter Introduction
|
|
|
|
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 @url{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.
|
|
|
|
@chapter Running FATE
|
|
|
|
@section Samples and References
|
|
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
|
|
@option{--samples=<path to the samples>} to @command{configure} or set the
|
|
@var{SAMPLES} Make variable or the @var{LIBAV_SAMPLES} environment variable
|
|
to a suitable value.
|
|
|
|
To use a custom wrapper to run the test, pass @option{--target-exec} to
|
|
@command{configure} or set the @var{TARGET_EXEC} Make variable.
|
|
|
|
The dataset is available through @command{rsync}, is possible to fetch
|
|
the current sample using the straight rsync command or through a specific
|
|
@ref{Makefile target}.
|
|
|
|
@example
|
|
# rsync -aL rsync://fate-suite.libav.org/fate-suite/ fate-suite
|
|
@end example
|
|
|
|
@example
|
|
# make fate-rsync SAMPLES=fate-suite
|
|
@end example
|
|
|
|
|
|
@chapter Manual Run
|
|
FATE regression test can be run through @command{make}.
|
|
Specific Makefile targets and Makefile variables are available:
|
|
|
|
@anchor{Makefile target}
|
|
@section FATE Makefile targets
|
|
|
|
@table @option
|
|
@item fate-list
|
|
List all fate/regression test targets.
|
|
|
|
@item fate-rsync
|
|
Shortcut to download the fate test samples to the specified test suite location.
|
|
|
|
@item fate
|
|
Run the FATE test suite (requires the fate-suite dataset).
|
|
@end table
|
|
|
|
@section FATE Makefile variables
|
|
@table @option
|
|
@item V
|
|
Verbosity level, can be set to 0, 1 or 2.
|
|
|
|
@table @option
|
|
@item 0
|
|
show just the test arguments
|
|
|
|
@item 1
|
|
show just the command used in the test
|
|
|
|
@item 2
|
|
show everything
|
|
@end table
|
|
|
|
@item SAMPLES
|
|
Specify or override the path to the FATE samples at make time, it has a
|
|
meaning only while running the regression tests.
|
|
|
|
@item THREADS
|
|
Specify how many threads to use while running regression tests, it is
|
|
quite useful to detect thread-related regressions.
|
|
|
|
@item THREAD_TYPE
|
|
Specify which threading strategy test, either @var{slice} or @var{frame},
|
|
by default @var{slice+frame}
|
|
|
|
@item CPUFLAGS
|
|
Specify a mask to be applied to autodetected CPU flags.
|
|
|
|
@item TARGET_EXEC
|
|
Specify or override the wrapper used to run the tests.
|
|
|
|
@item GEN
|
|
Set to @var{1} to generate the missing or mismatched references.
|
|
|
|
@item HWACCEL
|
|
Specify which hardware acceleration to use while running regression tests,
|
|
by default none is used.
|
|
|
|
@end table
|
|
|
|
@example
|
|
make V=1 SAMPLES=/var/fate/samples THREADS=2 CPUFLAGS=mmx fate
|
|
@end example
|
|
|
|
@chapter Automated Tests
|
|
In order to automatically testing specific configurations, e.g. multiple
|
|
compilers, @command{tests/fate.sh} is provided.
|
|
|
|
This shell script builds Libav, runs the regression tests and prepares
|
|
a report that can be sent to @url{http://fate.libav.org/} or directly
|
|
examined locally.
|
|
|
|
@section Testing Profiles
|
|
The configuration file passed to @command{fate.sh} is shell scripts as well.
|
|
|
|
It must provide at least a @var{slot} identifier, the @var{repo} from
|
|
which fetch the sources, the @var{samples} directory, a @var{workdir} with
|
|
enough space to build and run all the tests.
|
|
Optional submit command @var{fate_recv} and a @var{comment} to describe
|
|
the testing profile are available.
|
|
|
|
Additional optional parameter to tune the Libav building and reporting process
|
|
can be passed.
|
|
|
|
@example
|
|
slot= # some unique identifier
|
|
repo=git://git.libav.org/libav.git # the source repository
|
|
#branch=release/10 # the branch to test
|
|
samples=/path/to/fate/samples
|
|
workdir= # directory in which to do all the work
|
|
fate_recv="ssh -T fate@@fate.libav.org" # command to submit report
|
|
comment= # optional description
|
|
build_only= # set to "yes" for a compile-only instance that skips tests
|
|
ignore_tests=
|
|
|
|
# the following are optional and map to configure options
|
|
arch=
|

extra_conf= # extra configure options not covered above
|
|
|
|
#make= # name of GNU make if not 'make'
|
|
makeopts= # extra options passed to 'make'
|
|
#makeopts_fate= # extra options passed to 'make' when running tests,
|
|
# defaulting to makeopts above if this is not set
|
|
#tar= # command to create a tar archive from its arguments on
|
|
# stdout, defaults to 'tar c'

@section Special Instances
|
|
The @var{TARGET_EXEC} option provides a way to run FATE wrapped in
|
|
@command{valgrind}, @command{qemu-user} or @command{wine} or on remote targets
|
|
through @command{ssh}.
|
|
|
|
@section Submitting Reports
|
|
In order to send reports you need to create an @command{ssh} key and send it
|
|
to @email{root@@libav.org}.
