Release Engineering
~~~~~~~~~~~~~~~~~~~
* SOFTWARE TO TEST
+ Use latest libburnia libraries code base from svn and bzr
(see top-level README for aditional library dependencies)
+ Alternatively, use latest all-in-one development tarball from:
http://www.gnu.org/software/xorriso/
* SETUP THE TEST ENVIRONMENT AND RUN THE TEST SUITE
+ All tests have to be run from the releng/ directory, within
libisoburn source tree. Self-generated data are stored in
./releng_generated_data/ directory, and the required space for
these data is about 300 megabytes. There is a 'master' script
called run_all_auto, which runs all scripts prefixed with auto_*.
+ Any auto_* script can be run on its own, regardless.
+ Any manual_* script is to be run on its own, only.
+ All scripts support -h, -help, --help and
print usage help when run without options.
* DELIVERING A NEW TEST SCRIPT
+ Start a new test script over the top of template_new_releng
+ Each completed script starts with auto_ or manual_ prefix
+ Each script' self-generated data are to be stored in
./releng_generated_data/scriptname/ directory
+ Keep the newly added script options in sync with other scripts
+ Throw FAIL string to stdout if any failure is detected
+ Return exit code 0 on success, non-zero on failure
+ Use different exit codes for any failure (range 0-31)

>>> introduce the test suite,
Directory ./releng of libisoburn contains a collection of test scripts and
auxiliary data. They exercise some typical use cases of building libisoburn
applications and running the ISO 9660 filesystem manipulation and CD/DVD/BD
burn program xorriso.
>>> inform about intended audience and resource needs,
It is assumed that libburn and libisofs are installed, so that libisoburn
can be configured and built. It is not mandatory that libisoburn is already
installed. The tests may use an installed xorriso program as well as a
freshly built one.
>>> auto and manual tests
There are two groups of test scripts:
auto_* gets started and watched by script run_all_auto.
These tests have a moderate resource consumption and do
not cause mechanical movements of drive trays.
manual_* get started by the user if desired.
Manual tests may create larger sets of temporary files,
may download test data from the internet, may need
system privileges beyond the reach of a sandbox user,
and operate the mechanics of a CD drive.
>>> tell how to run the tests,
The test scripts expect to get run while the working directory is
./releng
of a libisoburn source tree. E.g.: libisoburn-1.1.4/releng
They create all their temporary files underneath
./releng/releng_generated_data
Some of these files are persistent between tests.
Nevertheless it is safe to empty ./releng/releng_generated_data after
tests are done. The directory itself must be kept.
To run the unobtrusive automatic tests, build libisoburn and xorriso,
go to directory ./releng, and execute
./run_all_auto -x ../xorriso/xorriso
or if you want to use an installed xorriso program:
./run_all_auto -x $(type -p xorriso)
>>> list of manual tests
Currently there are the folling tests which should have the attention of
the user or require sysadmin considerations before they get run:
./manual_isojigdo -x ../xorriso/xorriso
Exercises the production of a bootable Debian GNU/Linux image and its Jigdo
files. This test downloads a Debian daily image for i386 of about 70 MB,
extracts its content and composes a new image.
Thus it needs about 250 MB of disk space in releng/releng_generated_data .
./manual_devices -x ../xorriso/xorriso
Exercises listing of all accessible optical drives and the examination of
a one of these drives. The user needs the permission to operate the CD
drives. This might involve the need for superuser authority.
The media tray of the examined drive will get loaded if it is not already.
>>> ./run_all_manual
>>> give hints what to do with FAIL results.
=============================================================================
TODO:
* move auto_isojigdo to manual_isojigdo
because of its resource consumption
* Remove NOTE|DEBUG|ALL from run_all_auto event class list
* Delete debian-testing-i386-businesscard.iso with ./run_all_auto -c
* manual_isojigdo proposes to run manual checks after it removed the
generated images.
* Have a script ./run_all_manual
* derive a GNU xorriso test suite from libisoburn test suite
