If I had the following code
public static <T> int count(List<T> list, T elem) {
int count = 0; // the result
for (int i=0; i < list.size(); i++) {
if (list.get(i).equals(elem))
count++;
}
return count;
}
Lets say I need to run a black box test,
Like so,
Input
[null], null Output should be 0
Firstly, is this a worthwhile test case? ( for black box testing)
If not,
Then I ask, are null values worth while tests for black box testing in any case?(in general)
Thanks
