When writing entirely new test files, we try to work to higher/different standards than the old tests. For example, see:

- https://github.com/tmpvar/jsdom/blob/master/test/window/console.js
- https://github.com/tmpvar/jsdom/blob/master/test/window/history.js
- https://github.com/tmpvar/jsdom/blob/master/test/jsdom/parsing.js

Specific recommendations:
- Settle on double quotes
- `"use strict";` at the top
- Use the `exports["description, or sentence in the 'should' form"] = function (t) { ... };` form
