Test Methods don't seem to send body

[jeregrine]

In real world usage the below works but in tests when I call

conn = post(conn, "/", %S/{"name":"Jason Stiebs","email":"jason@rokkincat.com"}/)

And I try to parse it

{res, json} = JSON.decode(conn.req_body)

I get the exception that I need to fetch req_body. But I already am

conn.fetch([:params, :body, :headers])

If I add :req_body it blows up every non-post test.

@jeregrine Can you post the whole test case?

I had the same problem, and I had to fix the arg I was passing to Dynamo.under_test() and setting the correct endpoint.

[jeregrine]

test "creates a new user" do
    conn = post(conn, "/", %S/{"name":"Jason","email":"jason@email.com"}/)

    resp = JSON.decode(conn.sent_body)
    assert Dict.get(resp, "name") == "Jason"
    assert Dict.get(resp, "email") == "jason@email.com"
    assert Dict.get(resp, "id") != nil
    assert Dict.get(resp, "created_at") != nil
    assert conn.status == 201
  end

Let me know if you need anything else @HashNuke the docs are not super clear so I was kind of shooting from the hip.

@jeregrine try:

conn = post("/", %S/{"name":"Jason","email":"jason@email.com"}/)

[devinus]

test's don't start with a conn like e.g. get does, so you're calling post/3 when you actually want to CREATE a test connection.

[jeregrine]

I believe I did try that first, but it failed so after looking at the source I tried that. Will try again.

@jeregrine The test you posted should fail to compile because of the undefined variable conn. Or am I missing something?

[jeregrine]

@ericmj this code is basically just me flailing trying to get it working :).

Now that I've got it to rebuild I'm getting errors that it cannot fetch :session from the request. I'll need to look into this more tonight.

@devinus, @jeregrine and others,

I'm sorry. I looked into this issue yesterday and put off posting an update on this thread and the Dynamo group.

The source of the issue is that the Test connection (Dynamo.Connection.Test) does not parse the raw request body into params[1], like the Cowboy connection module (Dynamo.Cowboy.Connection)[2]. So the tests in case_test.exs[3] pass, because it's checking for conn.sent_body but not for conn.params

I looked into making changes to parse the body, but that would involve parsing the headers to look for the www-url-encoded content type. In short, IMO, a lot of changes to the current code in the Test connection module.

I clarified with Jose about this on IRC. Plug does doesn't have this issue. The Plug Router API is complete. Maybe we should start making changes to Dynamo to run on top of Plug.

@devinus's call.

[1] - https://github.com/dynamo/dynamo/blob/master/lib/dynamo/connection/test.ex#L176-L180
[2] - https://github.com/dynamo/dynamo/blob/master/lib/dynamo/cowboy/connection.ex#L188-L193 and line-191 especially.
[3] - https://github.com/dynamo/dynamo/blob/master/test/dynamo/http/case_test.exs#L51-L54

[HashNuke]

And for the POST request the appropriate header isn't being set in the Test connection module, creates a connection with just a host header and nothing else - https://github.com/dynamo/dynamo/blob/master/lib/dynamo/connection/test.ex#L30-L38

So that's where IMO the changes have to start from.

👍 For integrating with Plug. If someone knows what needs to be done and is willing to task it out I'd be willing to help.

[HashNuke]

Count me in too.

@HashNuke Integration with Plug was always the plan. Plug was spawned out of discussions about extracting Dynamo's core. Integrating with Plug is going to be a huge endeavor as it means replacing a lot of components, so we need to make a plan.

[jeregrine]

@devinus maybe we start a branch and a PR with a TODO list embedded? Similar to how bootstrap does their big pushes? twbs/bootstrap#6342
