Core Tests
This module contains all the tests that pertain to the usage of the Tutorius
Core. This means that the Event Filters, the Finite State Machine and all the
related elements and interfaces are tested here.
Usage of actions and event filters is tested, but not the concrete actions
and event filters. Those are in their separate test module
"""
import unittest
import copy
import logging
from sugar.tutorius.tutorial import *
# The following tests are organized around 4 classes:
#
# Black box tests:
# Those tests should limit themselves to exercise the
# interface of the object so everything should be tested
# only through the interface the object offers. This will
# ease test maintenance since we anticipate most changes
# will be about the implementation of an object and not
# its interface.
#
# Tests definitions are written assuming the previous tests
# did complete correctly so the number of things to assert
# is minimal.
#
# Basic interface cases:
# Test the interface of the object for trivial cases
# just to assert that the functionality this object
# offers really works
#
# Limit cases:
# Test edge cases that cover more obscure usage
# scenarios but that should be valid nonetheless
#
# Error cases:
# Test wrong inputs to make sure that the object is hard
# to misuse and do generate proper errors
#
# White box tests:
# Those should be used only for really important algorithms
# to make sure they behave correctly in every cases, otherwise
# the tests will break each time we change something in the
# implementation
