Question

In my holder test file:

 test "name must be present" do
  holder = Holder.new(name: "name")
  assert holder.valid?
 end

 test "name must not be blank" do
  h = Holder.new(name: "    ")
  assert !h.valid?
 end

 test "name must not be nil" do
  h = Holder.new(name: nil)
  assert !h.valid?
 end

And my holder model looks like:

class Holder < ActiveRecord::Base
  attr_accessible :description, :name, :user_id

  validates_length_of :name, maximum: 75
  validates_length_of :description, maximum: 250

  validate :name, presence: true
end

But, when I run my tests the last two validations are still red. What do I need to do to test them so they turn green?

Answer 1

You forgot s in your validate. It has to be:

validates :name, presence: true

validate and validates are completely different methods.

See there: http://api.rubyonrails.org/classes/ActiveModel/Validations/ClassMethods.html.
