Besides normal calculations... Divide by zero. Make sure negative numbers work Check if rounding is correct

How do you test a function on a calculator?

Check if the calculator is a normal calculator or a scientific calculator. Verify that all the buttons are present and text written on them is readable. Check the arithmetic operations are working fine- +, -, /, * etc. Verify that BODMAS is applied in case of complex queries and the correct result is returned.

How do you test a calculator?

To test the calculator, give it the known inputs and check that it computes the known outputs. You then also need to test that each button has the desired effect on the internal stack.

Exercise the interface. Does it do what you expect?
Exercise the functionality. Does it do what you expect?
Exercise boundary conditions. Does it handle division by zero? How does it handle really big and really small values? Are there rounding errors that crop up?

by throwing it against a wall, if it breaks... then it wasn't meant to be.

Besides normal calculations...

Divide by zero.

Make sure negative numbers work

Check if rounding is correct
