The following User test passes with no problem, the user is valid:
user_test.rb:
require 'test_helper'
class UserTest < ActiveSupport::TestCase
def setup
@user = User.new(name: "Example User", email: "user@example.com", callsign: "example",
password: "foobar", password_confirmation: "foobar")
end
test "user should be valid" do
assert @user.valid?
end
end
User model:
class User < ActiveRecord::Base
attr_accessor :remember_token, :activation_token, :reset_token
has_many :personas, dependent: :destroy
has_secure_password
before_save do
email.downcase!
callsign.downcase!
end
before_create :create_activation_digest
validates :name, presence: true,
length: { maximum: 50 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-]+(?:\.[a-z\d\-]+)*\.[a-z]+\z/i
validates :email, presence: true,
format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
VALID_CALLSIGN_REGEX = /\A[a-z\d\-.\_]+\z/i
validates :callsign, presence: true,
length: { maximum: 20 },
format: { with: VALID_CALLSIGN_REGEX },
uniqueness: { case_sensitive: false }
validates :password, length: { minimum: 6 }, allow_blank: true
def to_param
callsign
end
.
.
end
However, when I set up exactly the same user in the persona_test, the validation fails. (The persona validation fails too, each User has_many personas)
persona_test.rb:
require 'test_helper'
class PersonaTest < ActiveSupport::TestCase
def setup
@user = User.new(name: "Example User", email: "user@example.com", callsign: "example",
password: "foobar", password_confirmation: "foobar")
@persona = @user.personas.build(name: "Bazman", callsign: "Baz")
end
test "user should be valid" do
assert @user.valid?
end
test "persona should be valid" do
assert @persona.valid?
end
end
Persona model:
class Persona < ActiveRecord::Base
belongs_to :user
before_save do
self.callsign.downcase!
set_persona_id
end
validates :name, presence: true,
length: { maximum: 50 }
VALID_CALLSIGN_REGEX = /\A[a-z\d\-.\_]+\z/i
validates :callsign, presence: true,
length: { maximum: 20 },
format: { with: VALID_CALLSIGN_REGEX },
uniqueness: { case_sensitive: false }
validates :user_id, presence: true
validates :persona_id, presence: true
def to_param
callsign
end
.
.
end

I don't understand why the User validation in persona_test.rb is failing when the setup user is identical to the one in user_test.rb. Are you not allowed to test Users in a Personas test? If so, how do I successfully test personas? Each persona belongs_to a user, so I have to create a user in order to create a persona.
EDIT:
persona_test.rb:
require 'test_helper'
class PersonaTest < ActiveSupport::TestCase
def setup
@user = User.new(name: "Example User", email: "user@example.com", callsign: "example",
password: "foobar", password_confirmation: "foobar")#, activated: true)
@persona = @user.personas.build(name: "Bazman", callsign: "Baz")
@persona.user = @user
@persona.persona_id = 1
end
test "user should be valid" do
assert @user.valid?, @user.errors.full_messages
end
test "persona should be valid" do
assert @persona.valid?, @persona.errors.full_messages
end
end
With the updated persona test above, I get the error message 'User can't be blank'. Why is
@persona.user = @user
not working?
In your persona model you have:
validates :user_id, presence: true
validates :persona_id, presence: true
But it doesn't look like a user_id is being set. Try setting it with @persona.user = @user
in your test.
Additionally, as a tool for debugging, you can print @persona.errors.full_messages
in your test to see where exactly it is not validating.
Eg assert @persona.valid?, @persona.errors.full_messages
Hope that helps.
EDIT : as per the comments below, the line should actually be @persona.user_id = @user.id
. Another way you could achieve the same effect is to actually save the records to the database. So in your setup function, you would use create
instead of build
. This would, however, be slower.
The reason for the failed assertion is that some validations in Persona
won't pass:
validates :user_id, presence: true
validates :persona_id, presence: true
The validations are run before saving them to the database. For new records, user_id
and persona_id
will still be nil
.
Because Persona
is invalid, the User
will be invalid in the other test as well.
