We are about to start a new project and realise that automated testing will have many benefits. The question at the moment is what tool to use, ideally it would be open source (ie no licence fees). I have no experience of using automation apart from some batch command.
The system to be tested is client/server using standard ethernet dual LANs. The operating system is Red Hat Enterprise Linux version 4 running on intel based hardware.
The system can hold 10,000 pages (or screens), some are static, some dynamic changing according to serial input messages received, some are linked from page to page. The system will initially contain minimum 1000 pages, typically 2-3,000 pages.
Tool would need to capture a page and compare either field(s) or the complete page with the test sample and give a test result.
There may be a requirement to check for correct colour(s) in fields and strings of characters.
