Example #1

def test_KnowledgeEngine_reset_declare_initialfact():
    from experta.engine import KnowledgeEngine

    ke = KnowledgeEngine()
    ke.reset()

    assert len(ke.facts) == 1

Example #2

def test_KnowledgeEngine_reset_resets_facts():
    from experta.engine import KnowledgeEngine

    ke.facts = None

    ke.reset()
    assert ke.facts is not None

Example #3
