hello guys, i have made a script and it's available online and I'm willing to sell it but before i sell it i want to track bugs to make sure it's ready i don't want to sell it and then get into the refund issue because the buyer found some bugs on it.. what are the minimum tests i should do before i offer my script for sale?? and i wish to find a place to send users to my demo and get some feedback to track bugs... best regards
Test every single line in the script. You still can't assure that there are no bugs, but you can assure that there are no glaring bugs. Test it in every version of every one of the major browsers (for IE that means versions 6, 7, 8, 9 and 10). Whatever you do, someone will install it on a non-standard PHP configuration, and it won't work, or it will work but not as expected.
You always can request ppl to test your product! that works better then try to find bugs yourselve, coz you know how the script works and what to do with it. New users don't have that and will see it as a new product!
Bugs are normal in programs. All of your major software that costs thousands of dollars have bugs. Support your program...if a bug is found offer an update not a refund.
I find it very useful to comment my code. I don't comment what I do but more why I do something. This will usually help me to detect any errors in the logic when it comes to bug fixing at some point in the future.
You should offer your script as a free "beta" trial to a certain amount of users who are able to test it. This was a few people will get the script for free and will find bugs for you.
