Arc ( http://www.paulgraham.com/arc.html ) is a new dialect of Lisp by Paul
Graham and others. There's a community effort to hack on Arc and improve it
over at the open Anarki git repository:
Seeing that a comperhensive test suite was absent, I decided to start writing
one. Being involved with the development of Test::Run and other TAP efforts,
I naturally decided to use TAP for it, and so I did. This turned out to be a
good idea because some of the test programs have been written in Perl.
I've written (and later on enhanced) a rudimentary implementation of a TAP
emitter in Arc. I also wrote some tests in Perl to test it. The Perl tests
use Test::More and Test::Trap ( http://search.cpan.org/dist/Test-Trap/ ). The
Arc tests use the TAP emitting library (found in arctap.arc in the
repository's root directory).
So far the work on the test suite uncovered several bugs in Arc and one bug in
Test::Run, and also results in some enhancments to Arc. Plus, I was able to
better familiarise myself with Arc, and naturally write test suite code which
helps prevents future regressions.
I should note that I used Test::Run because of its AlternateInterpreters
plugin (which is an idea I originally derived from something Ovid wrote).
Currently, my interpreters.conf.yml file reads:
- cmd: ./arc.sh
This uses ./arc.sh to run the tests by default. It's a bit more complicated
than that (see Test.sh), but still the Test-Harness-2.54's prove would not
do, because it seems the she-bang at the start of the file confuses the Arc
But so far using TAP for the Arc test suite seems like it has been a sound
