[Koha-devel] plack in production

[Brendan Gallagher]

Great info Gaetan!

What does everyone feel about these tests?  Can we get a little feedback
here so that we can get some good bugs going?

The can't call method "field" I've seen before - but I have always chalked
that up to a bad MARC record.  (Please let's kill MARC ;)  we can do better
;)  )

The other ones I haven't seen before.

Thanks,
Brendan
