How to write test cases for this function

Hi, Guys,
I met a interview questions today, the question is to test this bool function
bool match (string s, string p);
string p is a pattern string, that means include character such as '?' or '*'
e.g. if s = 'panic' and p='pani?', it will return true,
if s ='panic' and p ='p*', it will return true,
if s = 'panic' and p= '??' it will return false.

I don't know how to write down test cases and how to classify the test cases such as valid or invalid, boundary test , could anyone help me out?

Thanks in advance.

Hi irisli

I cudnt understand your question, but still i wud suggest is
you should write test case having string- s as the super set of p-pattern. means p must have each char assigend to s.

can u pl. test , what kind of testing it is....white/black. so that we can find a solution to it.

Hi, these are the following test cases which you can write for the asked function..
Let me tell
you first what I understood from the question because according to that I have written the cases.
According to what I
saw, string s and string p are compared and resulted true only if both characters match. (even one character from s can match p).
The "?" and "*" is just like replacement for any one character.
s=panic , p = pani? ------ Valid
s=panic , p = pani* ------ Valid
s=panic , p = p? ------ Valid
s=panic , p = p* ------ Valid
s=panic , p = p*nic ------ Valid
s=panic , p = p*ni? ------ InValid
s=panic , p = ?pnic ------ InValid
s=panic , p = ?? ------ InValid
s=panic , p = *? ------ InValid
s=panic , p = ** ------ InValid
s=panic , p = pan?? ------ InValid
These are few test cases which
I think can be written..
Correct me if am wrong..
