In manual test cases u check for the expected values(which 
is all ready specfied)so taking the base document that is 
SRS u check the Expected value and actual Value.

example:u have a url link in a web page say 
(www.mail.yahoo.com) when u click this link(expected is 
display login page) so when u click a link it should direct 
u to the exact path if that is done is say that the test 
case is passed.else u say it as failed
