That is more commonly called a "reference output file", or "golden 
output file".

The term "oracle" is more commonly used for a _method_ or tool to 
_generate_ the expected outputs from _any_ given inputs, for example an 
independent implementation of the computation (a "reference 
implementation").

See https://en.wikipedia.org/wiki/Oracle_(software_testing).

By the way, Mehdi, when you respond to a posting, please quote the part 
of the posting to which you are responding, as I have done above. This 
makes it much easier to follow the conversation, especially for people 
who may not have read the original posting.

I know that some news-readers (Google Groups, perhaps) display postings 
in chains so that the posting to which you are responding is visible, 
but this is not the case for all news-readers (for example, Thunderbird).
