render = ::Redcarpet::Render::HTML.new(hard_wrap: false)
extensions = {
  no_intra_emphasis: true,
  tables: true,
  autolink: true,
  strikethrough: true,
  disable_indented_code_blocks: true,
  superscript: true,
}
parser = ::Redcarpet::Markdown.new(render, extensions)

Example 1, the URL can be parsed as a <a> tag, it works.

subject.render("<html>\n\n<div>www.test.com</div></html>")
# => "<p><html></p>\n\n<p><div><a href=\"http://www.test.com\">www.test.com</a></div></html></p>\n"

Example 2, the first URL cannot be parsed as a <a> tag, only the second URL works.

subject.render("<html>\n\n<div>www.test.com</div>\n\n<div>www.test.com</div></html>")
# => "<p><html></p>\n\n<div>www.test.com</div>\n\n<p><div><a href=\"http://www.test.com\">www.test.com</a></div></html></p>\n"

Example 3, both URLs can be parsed correctly, the difference is there is only one line break in front of the first <div>.

subject.render("<html>\n<div>www.test.com</div>\n\n<div>www.test.com</div></html>")
# => "<p><html>\n<div><a href=\"http://www.test.com\">www.test.com</a></div></p>\n\n<p><div><a href=\"http://www.test.com\">www.test.com</a></div></html></p>\n"
