Failures:

  1) TodoList filters tasks by multiple tags
     Failure/Error: ]
       expected collection contained:  ["Do the 5th Ruby challenge.", "Grok Ruby."]
       actual collection contained:    ["Grok Ruby."]

  2) TodoList filtering by multiple tags matches only tasks with all the tags

  3) TodoList supports a conjuction of filters
     Failure/Error: filtered = todo_list.filter Criteria.status(:todo) & Criteria.priority(:high)

  5) TodoList supports a negation of filters
