Debugging?

[Admin]

i am heavily modifying a PHP based shopping cart (lots of functional changes and a complete redesign). i need to make sure this thing has no bugs in it before i deliver it to the client.

do any of you guys know if there is anything that i can run that will run through my code and check for any scripting errors that i cant find? ie. something that will just go through the pages automaticly and add stuff to the cart and check out like 2000 times and try to catch any errors....

that would be pretty cool, .. but i don't know. send me the url and i'll test it a bit.

I don't think that there is anything out there for that...I recommend taking the role of "dumb user" and seeing if you can come up with the errors. I did a shopping cart page with ASP a couple of months ago, here is some things that I found:

1. Make sure that that users can only enter numbers into the shopping cart, I found out in my page if the user entered a letter or left the any numeric field blank, an error would occur.

2. Make sure that the user can not enter negative numbers. Even though I told it to only accept numbers -1 was still acceptable and it reduced the total price at the end.

3. Make sure deleting items from the cart is possible and be sure to make it clear on how to delete items.

4. If your cart is also interacting with inventory control make sure that quantities are added and subtracted correctly if changes are made within the cart.

Thats all I can think of off hand. I hope this gives you some ideas on what to look for.
