Expected ? to be array got Hash from JSON response

[fmorales]

When I hit this uri
http://voteapi-cloud-test.telescope.tv/moderation/getMessages?topic_id=1000336

and use this expectation
expect_json_keys('?', [:position])

I get this error:

1. Test Endpoint - has the correct keys
   Failure/Error: expect_json_keys('?', [:position])
   Expected ? to be array got Hash from JSON response

I get the same error for *

Am I still running into a bug, or am I doing something wrong?

[sethpollack]

Yes, the ? and * are for checking against elements in an array. Your api is returning a hash. What are you trying to test for?

[fmorales]

I am trying to check that all the nodes returned contain :position, instead of just 0. How do I do that?

[sethpollack]

Offhand, you can loop through the keys on json_body and call expect_json_keys for each.

Something like this:

json_body.keys.each do |el|
  expect_json_keys(el.to_s, [:position])
end

@fmorales I just updated the example the last one had a bug in it.

An alternative approach to what @sethpollack posted, is to use a little bit of hackery:

    @json_body = json_body.values
    expect_json_keys('?', [:position])

This relies on some implementation details of airborne but will work as well. The main issue is that you're treating an object like that of an array. If we see more use cases for this in the future, we can add support to airborne for this.

Alex,
Thank you. That’s hacky, but it does in fact do what I need it to do. Thanks for much for pointing out how to do that.
