Answer / suneel reddy

Positive Testing: Testing the application functionality
with valid inputs and verifying that output is correct
Negative testing: Testing the application functionality
with invalid inputs and verifying the output
Difference is nothing but How the application behaves when
we enter some invalid inputs
Suppose if it accepts invalid input the application
functionality is wrong

Answer / v.l. pianmoia

Positive testing tries to prove that a given product
does what is suppose to do.When a test case verifies the
requirements of aa product with a set of expected output,
it is called Positive test case.
E.g :- A product delivering an error when it is expected
to give an error, is also part of positive testing.

Negative testing is done to show that the product
does not fail when an UNEXPECTED INPUT is given. A negative
test would be a product not delivering an error when it
should or delivering an error when it should not.

valid inputs.this is also called as "test to pass'
-ve testing: testing aimed at showing s/w does't work.
which is also know as 'test to fail"
BVA is the best example of -ve testing.
