Rails unit test - undefined method 'users'

I've been trying to figure out how to test, but nothing seems to solve my issue. Every time I try to run any test, I get this error:

NoMethodError: undefined method `users' for #<#<Class:0x00560775e00768>:0x00560775e00470>

How i run my test inside a model: ruby test/models/plan_test.rb

I am trying to run the most basic test (the one Rails gave me as an example), so it is not linked to any model/fixture. My model:

require File.expand_path("../../test_helper", __FILE__)

class PlanTest < ActiveSupport::TestCase
  test "the truth" do
    assert true
  end
end

I have created an empty test database, too, and when I try to add the fixtures inside the database, I get the same error.

Thank you for looking :)

Edit: Trace on the fixture command(rake db:fixtures:load RAILS_ENV=test --trace):

Try This:

one:
      email: [email protected]
      name: Ioana1
      password: MyString
      verified: 1
      token: MyString
      remember_token: MyString
      plan: p0
      subscription_id: 1
      subscription_next_bill_date:
      email_hash: 1
      referred_by_user: two (or the way you named the self reference)
      subscription_status: deleted

Check if you have a valid model file called app/models/user.rb and that if you generated the user model using rails g model user or if you have created a migration for the user table, that you run your migrations.

RAILS_ENV=test rake db:migrate

Your app/models/user.rb should contain at the very least:

 class User < ActiveRecord::Base
 end

UPDATE: Your comment below says you've deleted the migration file. You can always get your test DB to mirror development DB by doing rake db:test:prepare
