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
fun everyNth(
input: String,
n: Int,
): String {
return "" // You may need to remove this starter code
}
