Where is the id '42' coming from?

[webmaven]

I don't understand how any implementation can be compliant if the first expected ID the system generates must be 42.

[stephenplusplus]

@proppy is the blueprint guy, but I believe 42 is simply a placeholder for a value type. In other words, an id is an integer.

[proppy]

Yes, the spec doesn't enforce IDs it's just use them as placeholder and double-check that the payload types and structures (schema) match.

See https://github.com/apiaryio/api-blueprint/blob/master/API%20Blueprint%20Specification.md

[webmaven]

@proppy, the spec may not enforce it, but the tests are.

The Todo tests do a GET for /todos/42, so my implementation can't pass the 4th test:

request: 
body: 

headers: 
    User-Agent: Dredd/0.3.14 (Linux 3.11.0-26-generic; x64)

uri: /todos/42
method: GET


expected: 
headers: 
    Content-Type: application/json; charset=UTF-8

body: 
    {
        "id": 42,
        "title": "dredd",
        "completed": false
    }

statusCode: 200


actual: 
statusCode: 404
headers: 
    content-type: text/plain; charset=UTF-8
    cache-control: no-cache
    expires: Fri, 01 Jan 1990 00:00:00 GMT
    content-length: 27
    server: Development/2.0
    date: Sun, 02 Nov 2014 13:05:38 GMT

body: 
Sorry, Nothing at this URL.

Whereas I know that doing the query for localhost:8080/todos/4980856393302016 through Postman works:

{
id: 4980856393302016,
completed: false,
title: "dredd"
}

@proppy, same issue with PUT and DELETE for Todos.

[proppy]

@webmaven make sure you run the hooks with --hookfiles

[proppy]

Also see #3

[webmaven]

@proppy, this is how I have been running the tests: dredd todos.apib http://localhost:8080 --hookfiles=hooks.js

but it looks like I was missing an npm module. So now the GET passes, but PUT and DELETE still don't.

Here is an entire run:

Which npm install? Was the dep missing in package.json? Can you run again with --level silly

[webmaven]

The package I was missing was 'async'. Since I installed dredd manually, I didn't get all the requirements for the hooks file. Here is the run with --level silly

OK, after this I got the Todo DELETEs working by forcing the returned content-type to text/plain. PUTs still not passing, though.

[webmaven]

Turns out the test couldn't pass. I extended the hooks.js file (PR #8 ) and now all is (finally) well:

webmaven@workshop:~/projects/appengine-todos-morepath$ dredd todos.apib http://localhost:8080 --hookfiles=hooks.js

[stephenplusplus]

Just a note for @proppy -- we were getting a false positive from our implementation because of our magic .save method, that inserts if an entity doesn't exist.

[webmaven]

Ah, you were using get_or_insert() for Todo as well as the TodoList? Let me know if either of you have any suggestions for improving my implementation that is based on @proppy's early code: https://github.com/webmaven/appengine-todos-morepath
