You can test by simply doing this as well:

describe 'validations' do
  it { should validate_presence_of :firstname }
  it { should validate_presence_of :lastname  }
end

Take a look at the shoulda matchers for all such standard Rails Validation. This way is not just more concise but also takes care of the positive case. Meaning you then dont need to test the scenario mentioned below:

it "passed validations when first_name is set"
  user = User.create(:firstname => 'f', :lastname => 'l')
  user.errors[:first_name].should be_empty
  user.errors[:last_name].should be_empty
end
