Given a String, compute a new String by moving the first character to come after the next two , so "abc" yields "bca". Repeat this process for each subsequent group of 3 characters, so "abcdef" yields "bcaefd". Ignore any group of fewer than 3 characters at the end.

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
