Test ActiveModel::Serializer classes with Rspec

Question

Given the following ActiveModel::Serializer class:

class SampleSerializer < ActiveModel::Serializer
  attributes :id, :name
end

Answer 1

When using active_model_serializers, there is a much easier way by simply calling serializable_hash on the serializer:

it 'should include a correct name' do
  sample = FactoryBot.create(:sample)
  serializer = SampleSerializer.new(sample)
  expect(serializer.serializable_hash[:name]).to eq 'Heisenberg'
end
