Need space between `{` and `form`; and `"` and `}` according to the [jQuery style guide](http://contribute.jquery.org/style-guide/js/), eg:

```diff
- equal( formatUnit( 1, "millisecond", {form: "long"}, cldr ), "1 millisecond" );
+ equal( formatUnit( 1, "millisecond", { form: "long" }, cldr ), "1 millisecond" );
```
