"11) String with more than 255 characters." <- This is not a correct test case.
We are talking about reversing words of sentence but not characters of a word !
@Saurabh, I added that because internally the characters of the words would be reversed.
Actually I should have been specific about the number; for ASCII: 255 and for Unicode: 2,147,483,647
That test case was mainly for load/crash/performance testing. Correct me if I am wrong.
two more test cases are needed
1) string with even no. of word counts,
2) String with odd no. of word count
I think he was expecting this : (Probably a unit test).
1) Take "This is nice"
2) Put in the program = get the output "nice is This"
3) Take output "nice is This" put in program back , you should get original string. "This is nice". (If the program is right :))
To the above program automated with single word , >1 words , null , empty string , and one manual test would be good.
I am not QA BTW. Just a programmer.
