Title: Sustainable Web Development with Ruby on Rails: Regex incorrect (testing Helpers section)

This code fails:

“# test/helpers/application_helper_test.rb

class ApplicationHelperTest < ActionView::TestCase
test “styled_widget_id” do
rendered_component = styled_widget_id(“1.23”)
→
→ regexp = %r{
→ <span # match a span tag
→ [^>]* # ignore anything that isn’t >
→ > # match the > to close the opening tag
→ .* # anything at all in here (e.g. other tags)
→ 1.23 # the widget ID we expect, escaping the dot
→ .* # anything after it (e.g. other tags)
→ # closing span tag
→ }x

assert_match regexp, rendered_component
 assert rendered_component.html_safe?
end

end

The line:
→ [^>]* # ignore anything that isn’t >
should be:
→ .* # ignore anything that isn’t >
