Phlex::Testing::Nokogiri

Phlex::Testing::Nokogiri is a test helper that makes it possible to test components in isolation using Nokogiri.

IMPORTANT

Before you include any Phlex testing helpers, you’ll need to require phlex/testing, or phlex/rails/testing if you’re using Rails. You can either require the helpers at the top of each test file or in a test helper or configuration file that’s loaded by your test suite.

Non-Rails

require "phlex/testing"

Rails

require "phlex/rails/testing"

#render_fragment

Returns the rendered component as a Nokogiri::HTML5::DocumentFragment, which you can then make assertions against.

#render_document

Returns the rendered component as a Nokogiri::HTML5::Document. Use this if the component you’re testing is a full HTML document. That means it starts with a doctype and has html, head, and body tags.
