  - return type (integers, strings,...)
  - type domain (integers bellow a number, strings with a specific size, etc)

    Those are good ideas. I am already testing if the output is undefined or not, depending on the input parameters. Anything else? :-)
• Tie::Hash::Cannabinol (Score:1)

  by Beatnik (493)

  If I'm not mistaking, Dave won a bid at an auction to have tests written for Tie::Hash::Cannabinol [cpan.org] by Schwern. The results were mentioned during one of the last YAPCs. Maybe you can convince Schwern to do it for one of your modules? :)

    Well... he *is* coming to Portugal [uminho.pt]...

    However, I think I'd like to see those tests before that conference, so I guess I'll have to think something up :-)

    Schwern's tests for THC are here [cpan.org].
    
    He also wrote a comment somewhere on use.perl which explained how he came up with them - but I can't find that now.

  Test it lots of times, gather the results, and see if they are likely to be random: http://search.cpan.org/~dcantrell/Statistics-ChiSquare-0.5/lib/Statistics/ChiSqu are.pm [cpan.org]

    This is an interesting idea too :-)
    
    Anyone else? :-) (this is getting interesting)
• Whitebox testing (Score:1)

  You could whitebox test the function to see that it behaves correctly internally.
  
  I wrote a journal entry [perl.org] about Test::MockObject that touches this.

  This will only work if you're generating random results yourself, obvisouly. But it's such a nice idea... (I use it for filling DBs with test-data thats random, but still allways the same)
  
  From perldoc -f srand:
  
  

  
  You can call srand($seed) with the same $seed to reproduce the same sequence from rand(), but this is usually reserved for generating predictable results for testing or debugging
