Undefined method error while running rspec test - ruby

Question

All,
I am getting the following undefined method errors below when running my rspec tests. When I have gotten this error before I had a method misspelled or my order of execution caused it. I checked both along with some other posts on StackOverflow, but nothing helped. Can anyone offer any guidance?

For the post_spec.rb errors, check the Post model (see file app/models/post.rb) has the following methods defined in it:
up_votes
down_votes
points
Consider including the code for post.rb in your original question too.
For the vote_spec.rb errors, there is no #post variable, it will be nil. This error message hints at this:
Failure/Error: expect(#post.up_votes).to eq((-1) || eq(1))
NoMethodError: undefined method `up_votes' for nil:NilClass
