How to perform unit testing on void function with coverage

Question

I am new to unit testing.
I am trying to perform unit testing on the below code

public void send(Map<String, List<Integer>> mapOf){

     mapOf.forEach((k ,v) -> {
         v.stream().forEach(o ->{
             myList.add(o)
             message.push(o);
         });
     });
    }

message.push(o), pushes data to the database. <br/>

How can I Unit test this method?

I do not fully understand your example: What is myList used for? Is the code just writing all Integers to the data base, with the keys being ignored? And, why do you mention coverage in your question? — Dirk Herrmann, Feb 13 '19 at 21:37
