Bob's changeset Test Rig
These are (one version of) the scripts we've been using to do
"burn-in" testing on the changeset/do-changeset tools and larch's
mkpatch/dopatch.
They are not yet integrated into the configure/build system of
this package -- you have to run them by hand.
Briefly, these perform end-to-end checks on the changeset tools as
follows:
a) generate an ORIG tree with some random elements
b) copy ORIG to make a MOD tree. perform a randomly selected
bunch of edits on this tree (add and delete files, directories, and
symlinks, change file contents, rename things, etc.).
c) generate a changeset from ORIG to MOD
d) copy ORIG to make TARGET
e) apply the changeset to TARGET
f) compare MOD and TARGET
g) assign ORIG = NEW-ORIG
h) goto step (b)
There are various parameters you can tweak in the source code (e.g.,
changing the relatively likelihood of various edit operations). As
well, you test changeset/do-changeset or mkpatch/dopatch or
mkpatch/do-changeset or changeset/do-patch.
WARNING: skim the code a bit first. There is a hard-wired path
in run-tests.sh script -- the script will create files under that
directory AND `rm -rf' files under that directory: so read first and
run with caution.
Thanks to Robert Anderson for writing this suite and spending a number
of long nights on IRC as he sent me failed test cases (often carefully
minimized by hand) and I pushed back fixes to my archive mirror.
WHAT YOU CAN DO
*) Play with the parameters and do some long test runs.
*) Look for ways to verify and/or improve test case coverage.
*) Work on making it portable among posix shells (e.g., don't rely
on $RANDOM)
*) Generalize the tests to test other tagging methods.
*) Derive some new tests from this to test the archive transaction
commands: imprev, cmtrev, tagrev, and getrev.
*) Generalize the tests to test auto-changelogs
*) Other clever and helpful things :-)
