Support templates for defining examples

[hlship]

I'd like to be able to do the following:

    (do-template [key expected]
                 (it (format "should have the correct value for %s" key)
                     (should= expected (key @asset)

                              :resource-path "META-INF/assets/coffeescript-source.coffee"
                              :asset-path "coffeescript-source.coffee"
                              :content-type "text/javascript"
                              :compiled true
                              :size 160
                              :checksum compiled-coffeescript-checksum)))

That is, easily generate a series of examples (it blocks) from templates. Currently, when I do that:

I'm not quite sure where the nil is coming from.

[slagyr]

I suspect this is just a miscommunication. Speclj describe/context blocks try to be helpful by throwing Exceptions when they contain something that is NOT spec component, like nil. That's why you're getting the error.

You can get the behavior you want. Here's an example:

(defn my-template [expected input](it %28str "checks " input) (should= expected input)))

(describe "specs" (my-template 1 1) (my-template 1 2) )

(run-specs)

Am closing. Please reopen if I misunderstood.
