Testing with rspec

There is also an rspec matcher available with the gem

You can use shared examples to help test that models are including acts_as_paranoid properly. For example, the following shared examples can be created in spec/support/shared_examples/paranoia_examples.rb:

shared_examples_for 'a Paranoid model' do

  it { is_expected.to have_db_column(:deleted_at) }

  it { is_expected.to have_db_index(:deleted_at) }

  it 'adds a deleted_at where clause' do
    expect(described_class.all.where_sql).to include("deleted_at IS NULL")
  end

  it 'skips adding the deleted_at where clause when unscoped' do
    expect(described_class.unscoped.where_sql.to_s).not_to include("deleted_at")  # to_s to handle nil.
  end


end

And then all you need to do is include this in the specs for the model that should be acting as paranoid, like so:

it_behaves_like 'a Paranoid model'
