amen.describe "One-time message pad", (context) ->

  context.test "Create a message", (context) ->

    api = yield discover "http://localhost:8080"

    {response: {headers: {location}}} =
      (yield api.messages.create content: "Test Message")

    message = (api.message location)

    context.test "Retrieve a message", ->

      {data} = yield message.get()
      {content} = yield data
      assert.equal content, "Test Message"

    context.test "Retrieving a message deletes it", ->

      try
        yield message.get()
      catch e
        assert e.message.match /404/
        return true

      assert false, "Expected Error, but none was thrown"

So you couldn't do:

assert.throws -> (yield message.get())

?

Nope. I'm getting

 AssertionError: Missing expected exception.

I just ran this and it worked fine:

assert.throws -> throw "foo"
