Given two Strings, concatenate them and return the result. However, if the concatenation creates a double character where the Strings are joined, then omit one of the characters. So "abc" and "cat" yields "abcat", not "abccat".

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
