Re: [LTP] [RFC] Running Filesystem related Testcase within LTP

[Subrata M. <su...@li...>]

Hi Rishi,

Thanks for noting this down. I was already thinking of looking into such
issues in LTP where lots of test cases are not run by default. The
reasons for them being:
1) Requires special setup,
2) Some test cases are meant for specific FS types,
3) Some other unknown reasons, which needs to be investigated.

Now, here are the options that i would like to envisage:

1) See whether there are any tests under that ltp/testcases/kernel/fs
directory which can be integrated to the default ltp run, by making an
entry inside runtest/fs command file. If this can be done, then this
should be the first place to do it,
2) If they cannot be integrated to runtest/fs as they might require a
special setup, the we have the following approach:

Create a new command file call runtest/fs_all. This should basically
contain a proper documentation saying the special setup required to run
these and those tests. You can have a variable=set/unset combination(s)
to determine which tests to run and which not to, say:

RUN_MONGO=Y,
RUN_DMAPI=Y,
....
etc,

Depending on these values, the tests will be run. But even if these
values are set, the script should be able to verify if the setup is
complete, else the tests should not be run. Also simplify the setup by
giving users the options to know some setup variable/values dynamically.
Say, if we are doing a ext4 testing, then the tests will require a ext4
fs to be existing in the test machine. So, set up a variable in the
script like:

EXT4_PATH_SET=Y
EXT4_DIRECTORY_TEST_PATH=/tmp/abcdef
..
things like that. Let the user mention the rest,

3) Once that is done, i would like to revive/rewrite the entire
ltp/runalltests.sh, which will be then used to run these special tests
as well as the default LTP tests. Entries in runalltests.sh can be like:

.......
./runltp <with desirable options>
./runltp -f fs_all
....

Things like that. Let me know what you think.

Regards--
Subrata
