Same as above.

You can also extract these two lines into a `before :each` to DRY up your code:

```
before :each do
  @shop = FactoryGirl.create(:shop)
  @review = FactoryGirl.create(:review, shop: shop)
end

scenario "User can edit a review they created" do
  user = @review.user
  # etc.
end

scenario "User can't see the edit button if did not create the review" do
  user = FactoryGirl.create(:user)
  login(user)
  # etc.
end
```
