test

{{and (test "is something model" item=item) (test "can read model")}} is used to perform a test on based on a type of model, almost the same as ember-can and the is helper, but is more generic and extensible whilst reading nicely:

{{#if (and (test "is crd intention" item=item) (test "can read intentions"))}}
I'm a CRD intention
{{/if}}

Consider using this instead of the can and is helpers, as its more generic.
