A)Test all cases
B)Identify boundary cases and test them
C)Check all cases by hand
D)Assume invalid input will never occur

Testing all cases can be impractical or even impossible, so identifying boundary cases (i.e. the inputs that are most likely to cause errors) and testing them can help catch most issues. Checking all cases by hand can be time-consuming and error-prone, so testing is usually done via automated tools or scripts. Assuming invalid input will never occur is a dangerous assumption, as it can lead to unexpected crashes or errors.
