Rails中的单元测试问题

Question

I'm trying to run my simple UserTest

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  fixtures :users

  test "user attributes must not be empty" do
    user = users(:valid_user)
    assert user.invalid?
    assert user.errors[:nome].any?
    assert user.errors[:cognome].any?
    assert user.errors[:localita].any?
    assert user.errors[:provincia].any?
    assert user.errors[:nazione].any?
    assert user.errors[:cap].any?
    assert user.errors[:indirizzo].any?
    assert user.errors[:civico].any?
    assert user.errors[:telefono].any?
    assert user.errors[:mail].any?
    assert user.errors[:username].any?
    assert user.errors[:password].any?
  end

end

with this users.yaml

valid_user:
  nome: prova
  cognome: prova
  localita: prova
  provincia: prova
  nazione: prova
  cap: 00000
  indirizzo: strada di prova
  civico: 1
  telefono: 1111111111
  mail: prova@prova.com
  username: prova
  password: prova

but it returns this error:

Loaded suite /var/lib/gems/1.9.1/gems/rake-0.9.2.2/lib/rake/rake_test_loader Started F Finished in 0.182523 seconds.

1) Failure: test_user_attributes_must_not_be_empty(UserTest) [../unit/user_test.rb: 10]: Failed assertion, no message given.

1 tests, 2 assertions, 1 failures, 0 errors, 0 skips

What's the problem?

Answer 1

well, Failed assertion is

assert user.errors[:nome].any?

which means that there are no errors on attribute :nome

why are you asserting that there should be errors on that attribute is a complete mystery to me

maybe you wanted to use errors[:nome].none? ?
