[gentoo-dev] A unit-testing prototype

Hi everyone,

A while back, vapier added some tests for the toolchain-funcs eclass to 
/usr/portage/eclass/tests/. I really like the idea, and I recently 
discovered an xUnit-style unit-testing framework for shell scripts 
called ShUnit2. I played with it a little and made a couple of 
prototypes. Take a look and see what you think.

To get started:

layman -f -o http://gechi-overlay.sf.net/layman.xml -a gechi
emerge shunit2
sed -i -e "/^__SHUNIT_SHELL_FLAGS/s:u::g" /usr/share/shunit2/shunit2

Download the attached files to /usr/portage/eclass/tests, make 'em 
executable and run 'em. The output looks something like this:

donnie@comet $ ./toolchain-funcs-shunit.sh 
#
# Performing tests
#
test-tc-arch-kernel
test-tc-arch

#
# Test report
#

donnie@comet $ ./x-modular-shunit.sh

What do you think?

Thanks,
Donnie

I've heard two positive comments on IRC and nothing else, so I'm 
proceeding with this. I'll be adding these to the existing 
/usr/portage/eclass/tests/, adding shunit2 to the tree, and beginning 
some work looking into unit tests for portage's bash code.

Probably some for app-shells/bash would also be useful, since we seem to 
pretty consistently run into weird breakage on new versions.

Thanks,
Donnie

Great! Thanks. I didn't try it because I was too lazy to put shunit2 in
an overlay but had a look at the code. Tests cannot hurt, esp. for such
widely used code that eclasses are.
I'll probably use this to write tests for the couple of eclasses I
maintain.


Alexis.

Could you let us know of your progress here or on your blog? I'm 
interested in maybe writing a couple tests for the gnome2* eclasses.

Thanks for your work on this :)

Cheers
