Test Writing: OurComparable Max

Created By: Geoffrey Challen
/ Version: 2021.3.0

Create a method named max. max should accept an array of objects that implement OurComparable and return the maximum. Require that the array be non-empty.

As a reminder, compareTo returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the passed object. Kotlin also allows you to use comparison operators directly with classes that implement compareTo. OurComparable works exactly the same as the official Comparable interface, except it is slightly simplified and does not accept a type parameter.

Test Design Challenge

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

  • Provide a public class named TestMax with a single non-private class 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
