assert_select_encoded(element = nil, &block) public

Extracts the content of an element, treats it as encoded HTML and runs nested assertion on it.

You typically call this method within another assertion to operate on all currently selected elements. You can also pass an element or array of elements.

The content of each element is un-encoded, and wrapped in the root element encoded. It then calls the block with all un-encoded elements.

# Selects all bold tags from within the title of an Atom feed's entries (perhaps to nab a section name prefix)
assert_select "feed[xmlns='http://www.w3.org/2005/Atom']" do
  # Select each entry item and then the title item
  assert_select "entry>title" do
    # Run assertions on the encoded title elements
    assert_select_encoded do
      assert_select "b"
    end
  end
end

# Selects all paragraph tags from within the description of an RSS feed
assert_select "rss[version=2.0]" do
  # Select description element of each feed item.
  assert_select "channel>item>description" do
    # Run assertions on the encoded elements.
    assert_select_encoded do
      assert_select "p"
    end
  end
end
