12@chapter Introduction
13
14FATE provides a regression testsuite embedded within the Libav build system.
15It can be run locally and optionally configured to send reports to a web
16aggregator and viewer @url{http://fate.libav.org}.
17
18It is advised to run FATE before submitting patches to the current codebase
19and provide new tests when submitting patches to add additional features.

21@chapter Running FATE
22
23@section Samples and References
24In order to run, FATE needs a large amount of data (samples and references)
25that is provided separately from the actual source distribution.
26
27To inform the build system about the testsuite location, pass
28@option{--samples=<path to the samples>} to @command{configure} or set the
29@var{SAMPLES} Make variable or the @var{FATE_SAMPLES} environment variable
30to a suitable value.
31
32The dataset is available through @command{rsync}, is possible to fetch
33the current sample using the straight rsync command or through a specific
34@ref{Makefile target}.
35
36@example
37# rsync -aL rsync://fate-suite.libav.org/fate-suite/ fate-suite
38@end example
39
40@example
41# make fate-rsync SAMPLES=fate-suite
42@end example
43

45@chapter Manual Run
46FATE regression test can be run through @command{make}.
47Specific Makefile targets and Makefile variables are available:
48
49@anchor{Makefile target}
50@section FATE Makefile targets
51@table @option
52@item fate-list
53List all fate/regression test targets.
54@item fate-rsync
55Shortcut to download the fate test samples to the specified testsuite location.
56@item fate
57Run the FATE test suite (requires the fate-suite dataset).
58@end table
59
60@section Fate Makefile variables
61@table @option
62@item V
63Verbosity level, can be set to 0, 1 or 2.
64@table @option
65    @item 0
66    show just the test arguments
67    @item 1
68    show just the command used in the test
69    @item 2
70    show everything
71@end table
72@item SAMPLES
73Specify or override the path to the FATE samples at make time, it has a
74meaning only while running the regression tests.
75@item THREADS
76Specify how many threads to use while running regression tests, it is
77quite useful to detect thread-related regressions.
78@end table
79
80@example
81    make V=1 SAMPLES=/var/fate/samples THREADS=2 fate
82@end example
83
84@chapter Automated Tests
85In order to automatically testing specific configurations, e.g. multiple
86compilers, @command{tests/fate.sh} is provided.
87
88This shell script builds Libav, runs the regression tests and prepares a
89report that can be sent to @url{fate.libav.org} or directly examined locally.
90
91@section Testing Profiles
92The configuration file passed to @command{fate.sh} is shell scripts as well.
93
94It must provide at least a @var{slot} identifier, the @var{repo} from
95which fetch the sources, the @var{samples} directory, a @var{workdir} with
96enough space to build and run all the tests.
97Optional submit command @var{fate_recv} and a @var{comment} to describe
98the testing profile are available.
99
100Additional optional parameter to tune the Libav building and reporting process
101can be passed.
102
103@example
104slot=                                   # some unique identifier
105repo=git://git.libav.org/libav.git      # the source repository
106samples=/path/to/fate/samples
107workdir=                                # directory in which to do all the work
108fate_recv="ssh -T fate@@fate.libav.org"  # command to submit report
109comment=                                # optional description

126makeopts=       # extra options passed to 'make'
127#tar=           # command to create a tar archive from its arguments on
128                # stdout, defaults to 'tar c'
129@end example

131@section Submitting Reports
132In order to send reports you need to create an @command{ssh} key and send it
133to @email{root@@libav.org}.
134The current server fingerprint is @var{a4:99:d7:d3:1c:92:0d:56:d6:d5:61:be:01:ae:7d:e6}
