I would format the line more like this: 

```javascript
var tests = [
    "slash",
    // ...
    "spaces",
    { name: "id", rule: "id", multiple: true},
    "comment", 
    // ...
]
```

I think it's easier to change test precedence this way, to distinguish short form (only a string) and detailed form (object), and to visually get the whole array at once.
