We are testing the todays_posts method from the model Dashboard here.

We should then call todays_posts on dashboard, not posts.
So the RSpec expectations in this test should be:

+ expect(dashboard.todays_posts).to eq posts_published_today
- expect(dashboard.posts).to eq posts_published_today

We could also rename the test as

+ describe "#todays_posts"
- describe "#posts"
