We have many different sites developed using magento 1.4. I need to develop functional tests like login, place an order etc, full user journeys for these. I am using test automation framework (taf also known as mtaf) to do so. Even though this is deprecated and doesn't support Magento 1.4, I understand we can build our own testcases on it and not use the pre written test cases. I plan on using selenium with it.
My question is since all magento sites use same cascading style sheets which may include same id s, classes, names etc, can I use the same set of functional tests across websites, since the css selectors used across are the same?
Or Am i totally wrong and its not the same set of selectors used across different magento websites? Is it because each website could be using a different theme and thereby resulting in different selectors?
Please share your thoughts.
