Boundary Value Analysis is a technique used for writing the
test cases..for example:If a particular field accepts the
values from 1 to 1000, then we test that field by entering
only 1, 1000, 0, 1001, 999,2.

i.e we check on the boundaries and then minimum-1 , minimum
+1 and maximum+1, maximum-1.

Answer / shravanthivijay

Boundary value analysis is one of the technique in Black box
testing,it is very useful to write test scenorious and test
cases for example: test the values from 1-1000 and to find
out the defects. dnot test all values from 1 to 1000. In
this situation use the boundary value analysis, min is 1 and
max is 1000.
min=1 PASS; max=1000 PASS ; min-1=0 FAIL :max-1=999
PASS
min+1=2 PASS; max+1=1001 FAIl
it is help ful to save the time
