Práctica p4-t2-networking

• Lea el Capítulo 3 “Networking with Sockets” de Node.js 8 the Right Way y resuelva los problemas en la secciónes Testability y Robustness

Testability exercises

• Add a unit test for a single message that is split over two or more data events from the stream
• 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. See npm package dev-null

Robustness exercises

• The LDJClient already handles the case in which a properly formatted JSON string is split over multiply lines. What happen if the incoming data is not a properly formatted JSON string?
• Write a test case that sends a data event that is not JSON. What do you think on how to manage this case?
• What happens if the last data event completes a a JSON message, but without the trailing new line?
• Write a case where the stream object sends a data event containing JSON but no newline, followed by a close event. How will you manage this case?
• Should LDJClient emit a close event for its listeners?
