Nagative Testing:

Take an example suppose ur in ur Login screen u
have username and Pwd text fields are availabel .The

message as "Enter value is invalid".
we are inputing the negative values and we are checking

Answer / chaitali

Negative testing is nothing but the testing with invalid data.
when we do adhoc testing at that time it is more useful.
In adhoc testing user dont know what is valid or
invalid.During such adhoc testing system should not
crash.For this purpose negative testing is done.

clear me if i m wrong.

Answer / shakun garg

One of the main testing principle:
"Destructive approach for constructive testing"
Some time tester should think like a hacker to identify loopholes in application.
To fulfill this tester should follow negative testing to justify system behavior of system in negative conditions.
