This won't work because you already have a handle on each of these
objects. They are likely deleted from the database, but destroying an
object (in AR terms) does not turn an instance of it to nil.
Give this a shot:
lambda { Comment.find(comment_1.id) }.should
raise_error(ActiveRecord::RecordNotFound)
lambda { Comment.find(comment_2.id) }.should
raise_error(ActiveRecord::RecordNotFound)
Although generally I prefer to keep only one expectation per example.
