Can you tell me what is boundary value analysis and
Equivalence partitioning, and error guessing with examples

Answer Posted / viji

Boundary value analysis:
The values for the test cases are selected from the
boundaries and are given as input to the system.

selecting boundary values:

If we have a class with values from min to max
Test for input data at min-1, min, min+1, max-1, max and at
max+1.

example for bva: Y2K compliance tool kit:

The tool sets the system date to 31st Dec and to 1st Jan
and see for the proper roll over of the system.

Equivalence partition:

Splitting the inputs and outputs of the software under test
into a number of partitions.

Error guessing:
There is no formal procedure based on experience they will
test.

for example:
Incorrect assumption
