how to write test cases for a function

[irisli]

I met a question about how to write test cases for a function? for example, the function :
bool match (string s, string p); if s matchs p, return true , otherwise return false. string p is kind of pattern (e.g. '?'--matchc one character; '*'-- match one or more characters)
e.g S P expected result
panic pani? true
panic p* true
panic ?nic false

in my mind, I donot know how to classfy the test cases so that make the test case matrix.
Could anyone help me out?

Thanks in advance.

hi irisli

i can give some suggestion regarding this

For ex: the data i have taken the testdata as king

1. s=king and p=king =pass
2. s=king and p=kin? =pass
3. s=king and p=k* =pass
4. s=king and p=blank space =false
5. s=king and p=!@#$% =false
6. s=king and p=? =false
7. s=king and p=* =false
8. s=king and p=ki? =false
9. s=king and p=*t =false
10. s=kin and p=king =false
like this you match the condition and prepare the test cases

Thanks

hi senthil,

If you take test data for king here i am assigning the actual value of king to s and expected value p to k* and then checking whether the condition is s=p

if s=king and p=k*then
condition true
else
condition false
end if

Thanks

hi senthil,

ya you have to test the functionality like this. Don't confuse test case with functionality

Thanks
