Boundry value Analysis: Boundry value of the given Input of 
the object. That is max and min.
ex:- If an test boc taking values 3-8. so the boundry 
conditions are 

min 3 - pass

min-1 2 - fail

min+1 4 - pass

max 8 - pass

max+1 9 - fail

max-1 7 - pass


Equalience call partaning:- Methodically reducessing the 
huge set of possible test cases in much smaller. But 
equally efficent. That means it depends on the type of the 
input value.

Ex:- Above Example. That particular text box accept only 
numeric. it does not allow any other.

a-z - fail

0-9 pass

Alpaha numeric special charectors fail

Equivallence partitioning is where if one clause pass the
all other clause of the sam type also passes e.g select one
value from dropdown pass means all values will pass

Boundary value anayalsis means that it will pass in the
boundries but it will fail as we go out side to it.
 eg sum of angles of a tringle is 180. it will fail when it
181 or 179
