| The test for browsers is `a-element.html`. The reusable format is `urltestdata.txt`, which |
| is not documented in detail. Reverse engineering through `urltestparser.js` should not be |
| too hard. Documentation welcome! |
| |
| [`annevk/url`](https://github.com/annevk/url) hosts some other files that might be of |
| interest if you want to create additional tests. |
| |
| Similar to `a-element.html` it would be trivial to add more tests for other objects that |
| expose links (e.g. URL and `<area>`). There's also room for enhancement and bits that |
| require independent tests: |
| |
| * The encoding part of the URL parser |
| * The state override part of the URL parser (setting individual properties of a URL) |
| * Origin serialization |
| * `application/x-www-form-urlencoded` |
