2)Input:Enter the date other than dd/mm/yyyy like yyyy/dd/mm
(or)mm/yyyy/dd (or) dd/yyyy/mm (or) mm/dd/yyyy
The date should not be accepted.

u have to take care whilewriting test case  that for date 
it should valid input from 1-31 and for month it should 1-
12 and for year it should 4 digits, and it should be in 
dd/mm/yyyy only anything apart from this formate it should 
give error message

Apart frm the above said answer.....we have to also 
consider the leap year...when it is not a leap year then dd 
should accept 1-28 for the month of feb and when it is a 
leap year it should accept dd from 1-29.

correct me if iam wrong.
