RSpec error resolution undefined method'name' in'user' factory

The error I got when I typed the rspec command.

Conclusion

The way to write the definition of FactoryBot is different.

code

Wrong writing

require 'rails_helper'
FactoryBot.define do
   factory :user do
     name "Example"
     sequence(:email) { |n| "tester#{n}@example.com" }
     password "password"
     password_confirmation "password"
     year "1 year"
     bio "hello!"
   end

end

Correct writing

require 'rails_helper'
FactoryBot.define do

  factory :user do
    name {"Example"}
    sequence(:email) { |n| "tester#{n}@example.com" }
    password {"password"}
    password_confirmation {"password"}
    year {"1 year"}
    bio {"hello!"}
  end
end
