Hello,
I am trying to get the Division example on the FIT wiki
http://fit.c2.com/wiki.cgi?WhatAndHowTalk
to run under Ruby and the Fit framework. I have 2 questions. First I
get red results on last 3 tests because the precision in the HTML
table is only up to 8 digits, but Ruby is calculating 15 digits.
And second, even after I adjust the HTML to match the results, they
till don’t equal. I am thinking this is because of ‘==’ vs. eql? on
floats.
Is there a way coerce a Ruby float to an aribitray precision via
truncate or round?
Thanks
Do you have a FIT fixture for running Ruby ?

Well, I have the Fit framwork d/l from the aforementioned Wiki. There
is apparently another
project in CVS on Rubyforge. Haven’t checked it out yet.

Ah.
If I remember correctly, there once was rumor that Dave T. was
working
on a FIT-like framework for Ruby …
I wonder whatever happened to that project…
I’ve written a little ruby replacement of FIT … I’ll probably post it
if
we don’t find that someone else has already done the work.
Haven’t taken the next step and built it into a wiki like the FITnesse
project …

I think that is the one I d/l from the wiki. Not sure though.

There is a version of RubyFIT in CVS on RubyForge. I tried it out and
it ran the Simple example (eg.Division) right out of the box. Solves
the precision problem by using a type adapter. Looking forward to how
that code addresses the 5 digit precision issue in Java v. Ruby.
So take a look at that one. If yours is better/different somehow, go
ahead and post it.

No. Float precision.

For testing float equality do what Test::Unit’s assert_in_delta does.
