I've created a helper function for my own purposes and thought it would be useful to others. So CPAN seems a sensible place to put it so others can use it if they want to...

It's function is simple - to go to the homepage of a website and return an array of URI's within that site, being careful not to stray outside it, that use the http or https scheme. It ignores things that aren't plain text or that it cannot parse such as PDFs or CSS files but includes Javascript files as links (thing like window.open or document.location.href) might be lurking there. It deliberately doesn't try to follow the action attribute of a form as that is probably meaningless without the form data.

As the Monastery has taught be that all published modules should have tests, I want to do it probably and provide those tests...

But, given that there is only one function and it makes HTTP requests, what should I test?

The obvious (to me) test is that it returns the right number of URIs from a website. But that number will likely change over time, so I cannot hardcode the 'right' answer into the tests. So beyond the necessary dependencies and their versions, I'd like some ideas of what should be in the tests, please.

In case you're interested, this came about from wanting to automate producing and installing sitemap files.
