render(options = {}, local_assigns = {}, &block) Link
rendered() Link
Returns the content rendered by the last render
call.
The returned object behaves like a string but also exposes a number of methods that allows you to parse the content string in formats registered using .register_parser
.
By default includes the following parsers:
.html
Parse the rendered
content String
into HTML. By default, this means a Nokogiri::XML::Node
.
test "renders HTML" do
article = Article.create!(title: "Hello, world")
render partial: "articles/article", locals: { article: article }
assert_pattern { rendered.html.at("main h1") => { content: "Hello, world" } }
end
To parse the rendered content into a Capybara::Simple::Node
, re-register an :html
parser with a call to Capybara.string
:
register_parser :html, -> rendered { Capybara.string(rendered) }
test "renders HTML" do
article = Article.create!(title: "Hello, world")
render partial: article
rendered.html.assert_css "h1", text: "Hello, world"
end
.json
Parse the rendered
content String
into JSON. By default, this means a ActiveSupport::HashWithIndifferentAccess
.
test "renders JSON" do
article = Article.create!(title: "Hello, world")
render formats: :json, partial: "articles/article", locals: { article: article }
assert_pattern { rendered.json => { title: "Hello, world" } }
end
