Testing Phlex Views

The Phlex::Testing::ViewHelper module defines render allowing you to render Phlex views directly in your tests and make assertions against the output.

You’ll need to require phlex/testing/view_helper and include Phlex::Testing::ViewHelper your test.

test/test_hello.rb

require "phlex/testing/view_helper"

class TestHello < Minitest::Test
	include Phlex::Testing::ViewHelper

	def test_hello_output_includes_name
		output = render Hello.new("Joel")
		assert_equal "<h1>Hello Joel</h1>", output
	end
end

hello.rb

class Hello < Phlex::HTML
	def initialize(name)
		@name = name
	end

	def template
		h1 { "Hello #{@name}" }
	end
end
