/ Adapted from CodingBat

Given a non-null String, consider the prefix made of the first n characters. Return true if that prefix string appears somewhere else in the string. Assume that the String is not empty and that n is between 1 and the length of the string, inclusive.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Java's assert method
