I think, rather KNOW it would be great if we could capture results to a log file. It would be even greater if we could capture it to a data source and map different results to data fields.

What I am after is a tool that allows some of the same goals as unit testing to be achieved. To see that expected results are there on original and on updates. (And it also will allow us to log exceptions.) By storing it in a database we could also have a special parameter we set for an individual request... so it would set an associated ID for the data file. I know that would be a minor pain... and I would love some of the functions if not all! Perhaps logging the URL into a data field would accomplish the same thing. (Except of course the issue of URL data being passed.) Maybe map it so requests from a certain URL get logged and possibly just the base URL with specific (form or URL variables)

That is all the features it would need to be super functional. (IMO)
