0.4.0

Added current_scale functionality

From now on, instead of using populate block and (re)creating records on each execution of block being tested, the user can add parameters to the block depending on current_scale. This method will return the current scale factor.

RSpec usage:

context "N+1", :n_plus_one do
  specify do
    expect { get :index, params: { limit: current_scale } }.to perform_constant_number_of_queries
  end
end

Minitest usage:

def test_no_n_plus_one
  assert_perform_constant_number_of_queries do
    get :index, params: { limit: current_scale }
  end
end
