If you find your model specs looking a little unDRY (repetitive) while testing the model validations, you may use a block to DRY your code.

So you can replace this:

it "should validates presence of first_name" do
  @user.should have_error_on(:first_name, :blank)
end

it "should validates presence of last_name" do
  @user.should have_error_on(:last_name, :blank)
end

it "should validates presence of login" do
  @user.should have_error_on(:login, :blank)
end

...

With this:

%w(first_name last_name login email password_hash).each do |attrib|
  it "should validates presence of #{attrib}" do
    @user.should have_error_on(attrib, :blank)
  end
end

Hope that helps!

PS. “have_error_on” is not standard in rSpec, but only a helper method.
