Tests written for the Shadow library.

The Shadow tests reside in the shadow/test directory. They are divided into the following subdirectories:

system: Shadow system tests. These tests require a network connection and AWS IoT credentials. The command line option -n may be passed to the test executable to disable these tests.
unit: Shadow unit tests. These tests do not require a network connection or credentials. These tests use the MQTT mocks.

See Test Configuration for configuration settings that change the behavior of the Shadow system tests. The Shadow unit tests require no special configuration.

The current Shadow tests use the Unity test framework. See Building and running the tests for a guide on running the tests.
