Comment (by seanleavey):

 This may also be related, but it seems that WordPress's testing bootstrap
 doesn't set the `home_url()` to the contents of the constant
 `WP_TESTS_DOMAIN`, so new posts created by e.g.
 `$this->factory->post->create()` inside unit tests have their permalink
 set to `localhost` (or presumably whatever the default is for the
 platform). This means that creating a post in a test with `post_content`
 set to contain a link to another post (retrieved via `get_permalink(
 $other_post )`), then running `wp_extract_urls` on its content, results in
 an array that doesn't contain the other post's URL.
