test-unit-capybara is a Capybara adapter for test-unit 2. You can get Capybara integrated Test::Unit::TestCase. It also provides useful assertions for Capybara.
% sudo gem install test-unit-capybara
require 'test/unit/capybara'
class MyRackApplication
def call(env)
html = <<-HTML
<html>
<head>
<title>Welcome! - my site</title>
</head>
<body>
<h1>Welcome!</h1>
<div class="header">
<p>No navigation.</p>
</div>
</body>
</html>
HTML
[200, {"Content-Type" => "text/html"}, [html]]
end
end
class TestMyRackApplication < Test::Unit::TestCase
include Capybara::DSL
def setup
Capybara.app = MyRackApplication.new
end
def test_title
visit("/")
within("h1") do
assert_equal("Welcome!", text)
end
end
def test_no_sidebar
visit("/")
within("body") do
assert_not_find(".sidebar")
end
end
def test_header_content
visit("/")
within(".header") do
find("ol.navi")
# This fails with the following message:
#
# <"ol.navi">(:css) expected to find a element in
# <<div class="header">
# <p>No navigation.</p>
# </div>>
#
# This messages shows the current context. You don't need to
# entire HTML. You just see the current context moved by "within".
# It helps you debug a problem without save_and_open_page.
