Thanks for the welcome and the information. Sorry for the delayed
response. I'm trying to get a project pushed out at work. Also sorry
if this reply is out of context, I was subscribed to the list digest
when I first posted.

I was also wondering if there is a list of any Dancer apps floating
around. I saw the links on  perldancer.org, but from looking through
them it seems that Dancer is being used just for parsing the URLs.

That isn't a criticism of course, I'm just super curious and I would
like to find some examples of applications built around Dancer so that
I can try and learn the style that is used. For example what is the
most common method for session storage, data storage, etc. Obviously
I'm reading the documentation, but I would love to look through some
real-life code too.

We currently produce Apache/CGI applications so I think Dancer would
be a huge difference since it would likely let us run things much
faster and we would be able to slot in new actions so much more easily
to make development easier. Of course there's still the convincing the
boss part of it that needs to be done :-) but that might be easier
with some smaller projects in Dancer.

Thank you for the info. I hadn't seen Test::TinyMocker before so I'll
look at that.

When I write tests (I know, it sounds horrible) I do use Test::More. I
mostly wanted to see what suggestions anyone had since the code is
available through the application as well as directly in the library.

Thanks. That is a surprisingly helpful guide to keep in mind.

It does. Thank you.
