Automated Testing

Technical Details

Tests do not have to be complicated or verbose to be effective
For a class, I had to refactor and rewrite some bio-informatics thingy
Here's my favorite excerpt from that program:

                                for ($i=0;$i<$scan_chain_length3;$i++){
                        $chain1[$i] =~ s/X/0/g; $chain2[$i] =~ s/X/0/g;
                        $chain3[$i] =~ s/X/0/g; $chain4[$i] =~ s/X/0/g;
                        $chain5[$i] =~ s/X/0/g; $chain6[$i] =~ s/X/0/g;
                        $chain7[$i] =~ s/X/0/g;
                                print OUTFILE2 "\n(ct_si  $ct_si{tdi}
        $chain1[$i]$chain2[$i]$chain3[$i]$chain4[$i]$chain5[$i]$chain6[$i]$chain7[$i]
         )";

I wanted to clean this up without breaking it
