What is error guessing?

Answer Posted / hemali

Error Guessing is a software testing design technique based
on the ability of the tester to draw on his past experience,
knowledge and intuition to predict where bugs will be found
in the software under test.

Error Guessing is a test case design technique where the
tetser has to guess what faults remaining in the program.

Some typical error areas to guess are: empty or null
strings, zero instances, occurrences, blank or null
characters in strings, negative numbers.

There are no specific tools and techniques to use for Error
Guessing:

test cases can be designed depending on the situation,
either drawing from functional documents or when an
unexpected/undocumented error is found while testing operations.
