Redis – Why am I getting unititialized constant in my Rspec model test?

I’m trying to create a test with Rspec in my rails application but I keep getting the following error.

uninitialized constant Build
# ./spec/models/build_spec.rb:3:in `<top (required)>'
No examples found.

I am running rails version 6.1.4.1. I also know that my model exists as I can create new objects that belong to that table in the ruby console.

here is my rspec file (spec/models/build_spec.rb)

require 'spec_helper'

RSpec.describe Build, type: :model do
  it "Has a name"
  it "is not valid without name"
  it "is not valid with too short name"
  it "is not valid with too long of a name"
end

here is my gemfile

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

    Check you have the right model inside the app/models/ directory.

    spec/models/build_spec.rb

    require 'rails_helper'

RSpec.describe Build, type: :model do
  it { expect(described_class.new).to be_a() }
end

    app/models/build.rb

    class Build < ApplicationRecord
end

    Hope this works for you.

    spec_helper does not load the environment (this includes not loading the models). You could either require the model file explicitly in this spec or require rails_helper instead.
