Given two non-null Strings, return a string of the form shorter + longer + shorter, with the shorter string on the outside and the longer string on the inside. If the two Strings are the same length, put the first String in the inside.

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 Kotlin's assert or check methods
