 ### `setValue`
 
 Sets a value on DOM element, including:
-- `<input>` (either `type="checkbox"` or `type="radio"`)
+- `<input>`
+  - `type="checkbox"` and `type="radio"` are detected and will have `element.checked` set
 - `<select>`
+  - `<option>` is detected and will have `element.selected` set
 
 Since this will often result in a DOM re-render, `setValue` returns `Vue.nextTick`, so you will often have to call this with `await` to ensure the DOM has been updated before making an assertion.
