 * I would focus on testing the state transitions, since character and
 * line counting are straightforward. The character count increments for
 * every character that is not EOF, and the line count increments whenever
 * a newline is encountered. Word counting is more complex because it
 * depends on correctly detecting boundaries. I would include test cases
 * with varying numbers of spaces, tabs, and newlines to verify that word
 * boundaries are handled correctly, since those inputs are the most likely
 * to reveal bugs.
