[Firebird-test] Using dejagnu to test the limit command

[Mark O'D. <mar...@lu...>]

Hi

While John (and Ann) have been doing their excellent work on limit, I've 
been having a play around with the tcs test system, mainly  I got there 
trying to test the fb2 build.

I've been looking at the dejagnu system (http://dejagnu.sourceforge.net).  

It was recommened by a couple of people as suitable for what we are 
trying to do, and is fairly simple to code test cases in.

So dejagnu is a fairly simple protocol built on top of the NIST expect 
tool (http://expect.nist.gov) - I've also written a couple of programs 
in expect and Im confident that it has the features that we needs.

The expect tool is itself an extension of the tcl language mainly for 
driving terminal driven applications.  For exercising the engine through 
isql it's perfect and in addition I've been able to convert two of the 
exising tcs test cases fairly easily.

So I was thinking we could use it to build a library of test cases for 
LIMIT.

Any thoughts?

Cheers

Mark
