GUARDARA has an import feature that allows importing messages from Wireshark network captures.

In this tutorial, you will not only find a real bug in an open-source MQTT message broker but also learn how to:

  1. Set up an external Engine
  2. Import messages from a Wireshark network capture into GUARDARA
  3. Set up a simple Test Flow
  4. Install GUARDARA extensions
  5. Configure a Project
  6. Start the test

This tutorial is a bit lengthy; however, you will find that once you know GUARDARA, the test setup discussed through this tutorial takes only about a minute. Once you start your test, finding your first bug takes only a couple of minutes.
