Hi,
I prepared a patch that adds EUnit-style tests to CouchDB:
http://friendpaste.com/2DAOEki94jg8SGfxheh769
The patch currently simply disables all tests that were available
in the ./test/ directory. The `couch_config_*` tests have been
migrated to the new EUnit style. The command-line based
JS test suite has yet to be enabled again. This is trivial.
The patch touches Makefiles'nstuff. Here's how to use it:
make local-clean
./bootstrap
./configure
cd test
make test
You should see (after a while):
...
/usr/local/bin/erlc -o ../src/couchdb/tests/ ../src/couchdb/tests/*.erl
erl -noshell -pa ../src/couchdb/ -pa ../src/couchdb/tests/ \
-eval "eunit:test([couch_config, couch_config_writer])" \
-s init stop
All 8 tests successful.
The output can be beautified. I kept it raw to show all that happens.
You see that this is still contained to the ./test/ directory. We'd
still
need to hook it up to the top level `make test`. I hope to get some help
with this.
Also, the conditional compilation with `erlc -DTEST` is not ideal yet.
I chose to use this to keep all test code out of code that will be
deployed,
but currently, all compiled `.beam` files get `rm`'d and recompiled with
`erlc -DTEST` on every test-suite run. Also, if you happen to run `make
install` from the top level directory, you'd install the test-enabled
beam
files. My lack of Autotools-fu prevented me from doing this more
elegantly
and again, I hope to get some help from the community.

Writing Tests
Hey, nice, you stuck around and like to know how to write tests now?
Easy:
1) Create a file `my_module_tests.erl` in src/couchdb/tests/ e.g.
`couch_config_tests.erl`.
2) Insert boilerplate header:
-module(my_module_tests).
-include_lib("eunit/include/eunit.hrl").
3) Start writing tests. See
http://svn.process-one.net/contribs/trunk/eunit/doc/overview-summary.html
for details. You can take the couch_config*_tests.erl files as guide,
but they are of poor quality and not yet good EUnit style. I tried to
change
as little as possible with this patch.
4)* Add my_module in line 28 of test/Makefile.am
5) cd test && make test
6) Go to step 3).
* This should be made more elegant as well as more test suites
are written.

What do you think?
