can any one give negative testcases for calculator

Answer Posted / anitha balasubramani

Negative testing is used to ensure whether the application can able to handle the invalid input and unexpected user behavior.For ex, if we give this data 4+5- and click equal to button then the calculator does not produce the result.To check these kind of behaviour we are doing negative testing. While doing negative testing the exceptions are expected. If it throws the exp properly in the negative testing then the application is working fine.
