Test a firestore rule like "allow list"

In unit-test-security-rules-v9, show should I test an `allow list` rule, like in this example of firestore rules:

```
match /users/{userId}/{allPaths=**} {
allow list: if request.auth.token.isAdmin;
}
```

In my use-case, I want to allow users to `get` their own info but only admins can `list` everybody.

Thanks
