FATE Automated Testing Environment
|
|
==================================
|
|
|
|
FATE is an extended regression suite on the client-side and a means
|
|
for results aggregation and presentation on the server-side.
|
|
|
|
The first part of this document explains how you can use FATE from
|
|
your FFmpeg source directory to test your ffmpeg binary. The second
|
|
part describes how you can run FATE to submit the results to FFmpeg's
|
|
FATE server.
|
|
|
|
In any way you can have a look at the publicly viewable FATE results
|
|
by visiting this website:
|
|
|
|
http://fate.ffmpeg.org/
|
|
|
|
This is especially recommended for all people contributing source
|
|
code to FFmpeg, as it can be seen if some test on some platform broke
|
|
with there recent contribution. This usually happens on the platforms
|
|
the developers could not test on.
|
|
|
|
The second part of this document describes how you can run FATE to
|
|
submit your results to FFmpeg's FATE server. If you want to submit your
|
|
results be sure to check that your combination of CPU, OS and compiler
|
|
is not already listed on the above mentioned website.
|
|
|
|
In the third part you can find a comprehensive listing of FATE makefile
|
|
targets and variables.
|
|
|
|
|
|
1. Using FATE from your FFmpeg source directory
|
|
-----------------------------------------------
|
|
|
|
If you want to run FATE on your machine you need to have the samples
|
|
in place. You can get the samples via the build target fate-rsync.
|
|
Use this command from the top-level source directory:
|
|
|
|
# make fate-rsync SAMPLES=fate-suite/
|
|
# make fate SAMPLES=fate-suite/
|
|
|
|
The above commands set the samples location by passing a makefile
|
|
variable via command line. It is also possible to set the samples
|
|
location at source configuration time by invoking configure with
|
|
`--samples=<path to the samples directory>'. Afterwards you can
|
|
invoke the makefile targets without setting the SAMPLES makefile
|
|
variable. This is illustrated by the following commands:
|
|
|
|
# ./configure --samples=fate-suite/
|
|
# make fate-rsync
|
|
# make fate
|
|
|
|
Yet another way to tell FATE about the location of the sample
|
|
directory is by making sure the environment variable FATE_SAMPLES
|
|
contains the path to your samples directory. This can be achieved
|
|
by e.g. putting that variable in your shell profile or by setting
|
|
it in your interactive session.
|
|
|
|
# FATE_SAMPLES=fate-suite/ make fate
|
|
|
|
NOTE:
|
|
Do not put a '~' character in the samples path to indicate a home
|
|
directory. Because of shell nuances, this will cause FATE to fail.
|
|
|
|
|
|
2. Submitting the results to the FFmpeg result aggregation server
|
|
-----------------------------------------------------------------
|
|
|
|
To submit your results to the server you should run fate through the
|
|
shell script tests/fate.sh from the FFmpeg sources. This script needs
|
|
to be invoked with a configuration file as its first argument.
|
|
|
|
# tests/fate.sh /path/to/fate_config
|
|
|
|
A configuration file template with comments describing the individual
|
|
configuration variables can be found at tests/fate_config.sh.template .
|
|
|
|
Create a configuration that suits your needs, based on the configuration
|
|
template. The `slot' configuration variable can be any string that is not
|
|
yet used, but it is suggested that you name it adhering to the following
|
|
pattern <arch>-<os>-<compiler>-<compiler version>. The configuration file
|
|
itself will be sourced in a shell script, therefore all shell features may
|
|
be used. This enables you to setup the environment as you need it for your
|
|
build.
|
|
|
|
For your first test runs the `fate_recv' variable should be empty or
|
|
commented out. This will run everything as normal except that it will omit
|
|
the submission of the results to the server. The following files should be
|
|
present in $workdir as specified in the configuration file:
|
|
|
|
- configure.log
|
|
- compile.log
|
|
- test.log
|
|
- report
|
|
- version
|
|
|
|
When you have everything working properly you can create an SSH key and
|
|
send its public part to the FATE server administrator.
|
|
|
|
Configure your SSH client to use public key authentication with that key
|
|
when connecting to the FATE server. Also do not forget to check the identity
|
|
of the server and to accept its host key. This can usually be achieved by
|
|
running your SSH client manually and killing it after you accepted the key.
|
|
The FATE server's fingerprint is:
|
|
|
|
b1:31:c8:79:3f:04:1d:f8:f2:23:26:5a:fd:55:fa:92
|
|
|
|
The only thing left is to automate the execution of the fate.sh script and
|
|
the synchronisation of the samples directory.
|
|
|
|
|
|
3. FATE makefile targets and variables
|
|
--------------------------------------
|
|
|
|
FATE Makefile targets:
|
|
|
|
fate-list
|
|
Will list all fate/regression test targets.
|
|
|
|
fate
|
|
Run the FATE test suite (requires the fate-suite dataset).
|
|
|
|
FATE Makefile variables:
|
|
|
|
V
|
|
Verbosity level, can be set to 0, 1 or 2.
|
|
* 0: show just the test arguments
|
|
* 1: show just the command used in the test
|
|
* 2: show everything
|
|
|
|
SAMPLES
|
|
Specify or override the path to the FATE samples at make time, it has a
|
|
meaning only while running the regression tests.
|
|
|
|
THREADS
|
|
Specify how many threads to use while running regression tests, it is
|
|
quite useful to detect thread-related regressions.
|
|
|
|
Example:
|
|
make V=1 SAMPLES=/var/fate/samples THREADS=2 fate
|
