RShade

Ruby Shade or RShade gem to help you to reveal which code are used in program execution.

trace = RShade::Trace.new  
trace.reveal do  
  #your code here
end
trace.show
#rspec
 rshade_reveal do
   #code here
 end

Example

I've took example from https://github.com/spree/spree code base. Wrap code to take a look what code used when you save variant. On huge codebase as spree it's helpful to know what callbacks are triggered and so on.

  context '#cost_currency' do
    context 'when cost currency is nil' do
      before { variant.cost_currency = nil }

      it 'populates cost currency with the default value on save', focus: true do
        rshade_reveal do
          variant.save!
        end
        expect(variant.cost_currency).to eql 'USD'
      end
    end
  end

Below is example how output will looks like. As you can see all code that have been use are printed.
