How to test

[building39]

I have this test:

describe "RSpec matcher" do
  subject { User }

  it "should ensure that attributes are validated" do
    should validate_url_of(:homepage)
  end
end'''

It fails with `undefined method`:

```Run options: include {:locations=>{"./spec/models/xxx.rb"=>[3]}}
F

Failures:

  1) RSpec matcher should ensure that attributes are validated
     Failure/Error: should validate_url_of(:homepage)
     
     NoMethodError:
       undefined method `validate_url_of' for #<RSpec::ExampleGroups::RSpecMatcher:0x0000000138ed88>
     # ./spec/models/xxx.rb:7:in `block (2 levels) in <top (required)>'

Finished in 0.00075 seconds (files took 0.0915 seconds to load)
1 example, 1 failure

Failed examples:

rspec ./spec/models/xxx.rb:6 # RSpec matcher should ensure that attributes are validated```

Clearly, I don't know what I'm doing. How can I get this test to work?

To be honest I don't know how to help you. Tests are passing and this gem is working in production. So, seems problem in your test

For some reason I have the same problem.

My model:

class LawProposal < ApplicationRecord
  validates :name, presence: true
  validates :url, presence: true, url: { allow_nil: true }
end

My spec file:

require 'rails_helper'

RSpec.describe LawProposal, type: :model do
  subject { LawProposal.new }

  context "validations" do
    it "has a name" do
      expect(subject).not_to be_valid
    end

    it "has an url" do
      should validate_url_of(:url)
    end
  end
end
