+# ESP32 mosquitto tests
+
+Mosquitto component doesn't have any tests yet, but we upcycle IDF mqtt tests and run them with the current version of mosquitto.
+For that we need to update the IDF test project's `idf_component.yml` file to reference this actual version of mosquitto.
+We also need to update some pytest decorators to run only relevant test cases. See the [replacement](./replace_decorators.py) script.
