[FIXED] problem of testing file worker in java

Issue

I have a question which is described below:

What problems would arise for testing a Java class which counts number of words in a file?

The function's signature is below:

public int wordCount(String filename)

Well, this is a junit testing question.
If you know the problem, what is the solution of that?

Solution

So your question is what to test for? If yes, I'd say you should check if the definition of "word" is implemented correctly (e.g. is "stack-overflow" one word or two), are new lines handled correctly, are numbers counted as words (e.g. difference between "8" and "eight"), are (groups of special) characters (e.g. a hyphen) counted correctly.

Additionally, you should test whether the method returns the expected value (or exception) if the file does not exist.

This should be a good starting point.
