More like: the request to the rebol unit test server would be: "Tell 
me all about PARSE on these Rebol versions..."

I see difficulty in testing something like a block!, because you 
would also have to test blocks in objects and look for possible side-effects, 
or what?

I'm not sure a hierarchy would work here - there are too many dimensions. 
Platform (Core, View, ...), platform (Windows, Linux, ...), version, 
test version, etc. Plus a test version would have applicable platforms, 
expiry both for bugs in the test and for changes in expectations, 
and cached results. I'm thinking of more of a formal test suite here 
than an arbitrary test server farm.

Test categories too, perhaps.

Blocks are probably too fundamental to rebol to worry about at an 
early stage, but unit tests could be made for any kind of behaviour 
or to test for any bug.

Brian, you're probably right.

Maybe RebDB could be used in this project? I've no experience with 
RebDB though, so I can't say, if it's suited.

I've done a relational database "NicomDB" as an education project 
2 years ago. It would be suited for this, and I've wanted to push 
it forward for some time. Maybe this is the opportunity? NicomDB 
is used on a webserver in a real application.

So it needs a database, and a web interface to be able to make queries 
to that.

The expiry and applicability info would help us distinguish between 
changes in intended behavior, buggy implementations, beta-vs-release 
and such. REBOL changes a lot even if many of those changes are fixes. 
This could act as a compatibility test suite for alternate implementations.

NicomDB could be used, possibly. We'd have to evaluate the options.

Geomol, what' s the application NicomDB is serving ?

I'll write you privately, as we don't want it to be exposed too much. 
(Users are depending on it, and this goups is web-public.)

Ok.  But this is becoming a very large and complex project. Are we 
really prepared to go through with it ?  I think even if we go a 
short way, the ideas and findings may help someone else come along 
to complete it later. So I think I will make that Qtask project.

Yes, do that as a start. We can move it later if needed.

I'll do some research and think about this some more. It may not 
be as difficult as it sounds.

rebdb is very easy too ... we now have even sqlite drivers ...

If anyone else wanna see the website powered by REBOL and running 
my NicomDB, write me privately.

Looks ok, nothing broke while I was fiddling with the website. :-) 
That's encouraging but not conclusive of how well it can really perform.

It's running on a FreeBSD server, so it's pretty robust. It hasn't 
been rebooted since July last summer.

is it on-disk db or memory based as rebdb is?

We had some problems with Netcraft sending strange HTTP headers, 
that sometimes made our REBOL application hiccup, but that should 
be solved.

Pekr, data is on-disk, multi-user locking is in memory.

interesting ... binary or plain text based? sql interface? :-)

Pekr, REBOL datatype based (so text, but you can store binary data).

Pekr, no SQL interface yet. I started to do a SQL interface doing 
my education, but didn't finish it. SQL is crap. ;)

why we did not know about this interesting project earlier? :-) was 
it private?

hehe, well. My problem is, I have so many things to do and so little 
time.

Pekr, I'll write you privately, so you can see the NicomDB in action 
in a real application.

ok, thanks ...

Ok, created a new Qtask Rebol SIG task, with many notes extracted 
from this discussion in its description. Sitll pretty messy, but 
it's a start.
http://www.qtask.com/details.cgi?project=198&id=38061

Having done that, I can't spend much time on it now ! :-(  But it's 
good to get some of these ideas written down, and a few things worked 
out.

It's been a while, since I last used Qtask. Do I need special permission 
to see that project?

I think you just need to login before you visit that url. Did you 
have trouble accessing it ?

(Or maybe a Lead such as Reichart needs to approve the task first 
? That might take some time...)

Yes, I don't have permission.

Reeeeiiiichart! It's Anton and John caaaalling! ;)

u don't?

I think you are on REBOL SIG.

Look at the regression tests implemented in Orca they already cover 
a lot of behaviour.

http://trac.geekisp.com/orca

They can serve as a base to implement the full unit test for Rebol, 
and save time.

If you download the src code the paths is user-path/orca/trunk/orca/tests/

Isn't there a regression test "suite" for Rebol programs? IIRC someone 
made something like this.

Or was it unit-testing...

I believe there is a Unit Test framework. But no rebol specific regression 
tests have been written. At least not publicly.

Geomol, are you able to login to Qtask still ?

Reichart has approved/released the task, so all I need to do is add 
interested people as watchers.

I see "John" in qtask and added him as a watcher. (I assume that's 
you Geomol). I can add anybody else in qtask who is interested as 
watchers too.

(Geomol, you will need to accept becoming a watcher first, then you 
should be able to see the page.)

Carl used to wax lyrically about the automated Rebol test suite that 
Jeff (Kreis) wrote when he was at RT. As far as I know it was never 
publicly available.

Anton, I have access to the project on Qtask now.

and yes, I'm John in Qtask.
