[erlang-questions] Erlang Testing frameworks, sorry.

Berlin,

I recently went through this same decision process and finally decided
to learn how to use Common Test. It's a part of the OTP distro, so you
don't have to worry about maintaining a separate version of the
testing framework somewhere and it's pretty easy to use once you get
it setup. It has some really nice reporting tools and is clearly a
very mature framework...it's just the install stuff that I have issues
with. :)

My "setup" involved investigating the run_test.in script found in
erlang/lib/common_test-<vsn>/priv. Once I figured out what that was
doing, I wrote a macro (included below) for GNU make that makes it
easy for me to add unit tests to an apps Makefile:

# --------------------------------------------------------------------
#
# Macro for running unit tests using common_test fx
#
# --------------------------------------------------------------------
define run-tests
@mkdir -p test/logs
@erl -pa $(PWD)/ebin $(PWD)/include \
        -noshell -s ct_run script_start -s erlang halt \
        -dir . -logdir test/logs \
        -env TEST_DIR $(PWD)/test $*
endef

With that macro included in my make file, I can run tests by creating
a directory named "test" and dropping test suites in that directory
with the appropriate names (foo_SUITE.erl, as the case may be). I
invoke the macro in my app's Makefile like so:

test:
     $(run-tests)

I know that this isn't the how the instructions in the common_test
system recommends doing things. However, from my perspective requiring
developers to copy the entire common_test and test_server apps to
another directory just so a .in file can be processed is a little
redundant. I'm sure there are downsides with my approach, but from a
development standpoint it works and is easy to work with.

Hope that helps...

D.
