"""
Tests for all of the components defined in components.py. Tests are divided into two types:
1. test_component_functions() are unit tests that check essential functions of a component, the functions that are checked are documented in the docstring.
2. test_in_interface() are functional tests that check a component's functionalities inside an Interface. Please do not use Interface.launch() in this file, as it slow downs the tests.
