GUI testing by click x,y

I want to ask for help to deal with GUI testing of Web Application.

I'm looking for software where I can write script which will do this:

• Click (x,y)


• Write data (like login, password)


• Check radio and checkboxes


• Validate output data

And it'd be very big + if it can change between windows.

I was trying to testing GUI by:

• Selenium


• JAutomation


• Sahi

However I couldn't test it by xpath because application:

• doesn't have unique id


• classes are changing every reloading


• absolute xpath depends on sequence of steps performed

Thanks in advance for your help!
