Cop idea: Negative be_valid matcher

[ydakuka]

Actual behavior

I have the code:

RSpec.describe AdvertForm, type: :model do
  subject(:form) { described_class.new }

  specify do
    expect(form).not_to be_valid
  end
end

I run rubocop:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop spec/forms/advert_form_spec.rb
Inspecting 1 file
.

1 file inspected, no offenses detected

Expected behavior

I expected to receive the following code:

RSpec.describe AdvertForm, type: :model do
  subject(:form) { described_class.new }

  specify do
    expect(form).to be_invalid
  end
end
