def params
  controller.params
end

#render(options = {}, local_assigns = {}, &block) ⇒ Object

:call-seq:

render
render(:template => "widgets/new.html.erb")
render({:partial => "widgets/widget.html.erb"}, {... locals ...})
render({:partial => "widgets/widget.html.erb"}, {... locals ...}) do ... end

Delegates to ActionView::Base#render, so see documentation on that for more info.

The only addition is that you can call render with no arguments, and RSpec will pass the top level description to render:

describe "widgets/new.html.erb" do
  it "shows all the widgets" do
    render # => view.render(:file => "widgets/new.html.erb")
    ...
  end
end

def render(options={}, local_assigns={}, &block)
  options = {:template => _default_file_to_render} if Hash === options and options.empty?
  super(options, local_assigns, &block)
end

#response ⇒ Object

Deprecated. Use rendered instead.

def response
  RSpec.deprecate("response", "rendered")
  rendered
end

#stub_template(hash) ⇒ Object

Simulates the presence of a template on the file system by adding a Rails’ FixtureResolver to the front of the view_paths list. Designed to help isolate view examples from partials rendered by the view template that is the subject of the example.

Example

stub_template("widgets/_widget.html.erb" => "This content.")

def stub_template(hash)
  view.view_paths.unshift(ActionView::FixtureResolver.new(hash))
end

#template ⇒ Object

Deprecated. Use view instead.

def template
  RSpec.deprecate("template","view")
  view
end

#view ⇒ Object

The instance of ActionView::Base that is used to render the template. Use this before the render call to stub any methods you want to stub on the view:

describe "widgets/new.html.erb" do
  it "shows all the widgets" do
    view.stub(:foo) { "foo" }
    render
    ...
  end
end
