I've a e-commerce script like oscommerce.
It has 2 part, the shop and the back-office. You've to work on the front-office only. Back-office will come later into a next project.
I want you to create a selenium test suite.
You've to create individual test for each feature of the shop, and with them create a test suite.
Tests must be robust. You can see test shop, i'll give you url by MP only.
