Describe some problems that you had with Selenium tool ?
Solution: The one big limitation in Selenium - Select a file in a File Input field for sake of uploading.
XPaths makes tests slow
Having Ids for elements make tests faster but the UI code might not have Ids for all elements
XPaths are brittle - ie flaky because if the UI developer changes anything like adding or removing a DIV, then the XPath becomes invalid and has to be updated in the tests.
