- (Object) render - (Object) render({:partial = > path_to_file}) - (Object) render({:partial = > path_to_file}, {... locals ...}) - (Object) render({:partial = > path_to_file}, {... locals ...})
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

- (Object) response
Use rendered
instead.

# File 'lib/rspec/rails/example/view_example_group.rb', line 105 def response # `assert_template` expects `response` to implement a #body method # like an `ActionDispatch::Response` does to force the view to # render. For backwards compatibility, we use #response as an alias # for #rendered, but it needs to implement #body to avoid # `assert_template` raising a `NoMethodError`. unless rendered.respond_to?(:body) def rendered.body self end end rendered end |
- (Object) stub_template(hash)
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.
stub_template("widgets/_widget.html.erb" => "This content.")

- (Object) view
The instance of ActionView::Base
that is used to render the template.
Use this to stub methods before calling render
.
describe "widgets/new.html.erb" do
it "shows all the widgets" do
view.stub(:foo) { "foo" }
render
# ...
end
