Thanks.

Is there an automatic process to update these if I update (or add) a 
test file?

Providing defaults is a good idea. I like it.

Right now I am using JavaScript's RegExp parser on '\%'+name+'\%'. I can 
see problems with backslashes or other RegEx control structures in name. 
Perhaps name should be limited to A-Za-z0-9\-_

The loop is over the list of supplied name/value pairs where the name is 
the hash of the value in the array. Once all of the array values have 
been processed, another pass would need to be done to handle the 
defaults. Anything left as %<string>% would need to be processed for an 
'=' and replaced with the default value.

Is that what you had in mind?
