[gentoo-dev] A unit-testing prototype

[Donnie Berkholz]

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

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

What do you think?

Thanks,
Donnie
