Rspec presence: true check fails even though it works as intended - ruby-on-rails

Question

I have the following Rspec test with the following output for my User model in a Rails API I'm building:
RSpec.describe User, type: :model do
let(:michael) { User.new(email: "michael#email.com", password: "Password1", password_confirmation: "Password1") }
it 'is not valid without a password' do
michael.password = ''
expect(michael).not_to be_valid, "Expect User to have a Password"
end
end
1) User basic checks is not valid without a password
Failure/Error: expect(michael).not_to be_valid, "Expect User to have a Password"
Expect User to have a Password
# ./spec/models/user_spec.rb:19:in `block (3 levels) in <main>'
However, for some reason this test just fails, even with the following on my User model
class User < ApplicationRecord
has_secure_password
validates :email, presence: true, uniqueness: true
validates :password, presence: true
validates :password,
format: { with: /\A(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).{8,}\Z/, message: "Password must be at least 8 characters long, contain at least 1 uppercase and 1 lowercase letter and 1 number" },
confirmation: true,
on: :create
end
The above validation works fine, as you can see here:
➜ rails c
Running via Spring preloader in process 2774
Loading development environment (Rails 6.0.3.1)
irb(main):001:0> new = User.new
irb(main):002:0> new.email = "testing#testing.com"
irb(main):003:0> new.save
(0.2ms) BEGIN
User Exists? (0.6ms) SELECT 1 AS one FROM "users" WHERE "users"."email" = $1 LIMIT $2 [["email", "testing#testing.com"], ["LIMIT", 1]]
(0.2ms) ROLLBACK
=> false
irb(main):004:0> new.errors
=> #<ActiveModel::Errors:0x00007f743848dfb0 #base=#<User id: nil, email: "testing#testing.com", password_digest: nil, created_at: nil, updated_at: nil, admin: false>, #messages={:password=>["can't be blank", "can't be blank", "Password must be at least 8 characters long, contain at least 1 uppercase and 1 lowercase letter and 1 number"]}, #details={:password=>[{:error=>:blank}, {:error=>:blank}, {:error=>:invalid, :value=>nil}]}>
What exactly am I doing wrong here for this test to fail? It's a painfully simple one, and all the other ones work as expected except for the password test.

Answer 1

First, in your tests password = '' is a valid one because for Ruby, '' is something. You have to add this to your validation:
validates :password, presence: true, allow_blank: false
Also, take a look, your password validation is for on: :create and in your spec you are not creating it.
