[SOLVED] Test:: fail when output file was changed

jahero has asked for the wisdom of the Perl Monks concerning the following question:

Dear fellow monks.

I think that some time ago I have seen somewhere information about a package on CPAN (in a blog post I think), which could be used in testing, and which:

by default failed, when named output file was changed
could run in such a mode, that it would "remember" current state of the file (if the change was intentional), which would prevent further fails (until next change)

Imagine you are programmatically creating complex structured text, and want to be able to "keep it fixed" in you tests - unless you know that the change is "for the better"

Is my memory playing tricks on me? Are you aware of such library? I hope that what I vaguely described above makes sense.

Unfortunately, mu Google-fu is not advanced enough to yield the answer.

Regards, Jan

Are you looking for [solved] Test module to compare results between different runs (save/load)? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

I think thats exactly it. Thank you for pointing me in the right direction (damned, it was SO obvious when thinking back)!	[reply]
