test/rails/render_tree.rb adds debug rendering to ActionView::Base#render.
Debug rendering prints out a tree of calls to render allowing you to easily visualize where rendering occurs in unfamiliar code.
RENDERS | = | [:partial, :template, :file, :action, :text, :inline, :nothing, :update] | List of render types for ActionView::Base#render |

Add debug output to rendering.
When you include lib/rails/render_tree a tree of renders will be displayed in the console. This is especially useful when writing tests.
This test:
require 'test/test_helper' require 'test/rails/render_tree' class ThingsViewTest < Test::Rails::ViewTestCase fixtures :goals def test_body assigns[:goal] = goals(:first) assigns[:related_goals_moved] = [] assigns[:related_goals_instead] = [] render :partial => 'things/body' assert_tag :tag => 'div', :attributes => { :id => 'entriesbucket' } end end
Will give this output when run:
