have any reliable technical support because its an open source software.
There are many applications Selenium doesn’t support including Mobile Native Applications and Mobile Hybrid Applications.
It needs manual configuration to setup tools and plugins
in Selenium to use Test Automation, on the contrary, UFT/QTP offers download and install the tools
New Functionality and features are not tested since it’s an
open source so they may work well or not are not ensured like other vendors.
No Test Management Task tool available in Selenium.
No Test Reporting facility available in Selenium, so users
may need to take help from other frameworks to generate test reports.
Selenium IDE (Selenium Integrated Development Environment) only support Firefox Browser and for Testing it doesn’t support any programing.
