Hi kumar,

Functional testing means, testing the functionality, just functionalitly. Say, we are testing the Gmail. In that we have to test whether inbox is opening properly, whether we can compose mail with out facing any problems,after clicking on login button whether we could see our mails, whether we can create any custom message in chat, whether we can add any contacts to our contacts lists..........In functional testing we write for every these functionality and we execute those test cases.

System testing means, Whether the Gmail can be accessed using different browsers like Internet explorers (all versions), Net scape navigator, MOzilla fox, and whether we can browse the website when we have Windows Xp, 2000,2003 server, and whether we can take printouts of the webpage.... In system testig we testing everything like hardware compatability, browser compatability everything we check.
