1. Add a unit test for a single message that is split over two or more data evetns from the stream:
   • El primer test ha sido ya implementado durante los ejemplos del capítulo:

   

2. Add a unit test that passes in null to the LDJClient constructor, and asserts that an error is thrown. Then make the test pass by modifying the constructor to accept null: the semantic being that the created stream behaves as /dev/null in Unix.

2. What happens if the last data event completes a a JSON message, but without the trailing new line?

3. Should LDJClient emit a close event for its listeners?
