Swagger Yaml Spec fails validation if response codes are not quoted

[the-destro]

using the yaml file from the swagger editor I saved it as a yaml file and tried to load it in the same way that the pyramid_swagger project loads the file. I get a "SwaggerValidationError: expected string or buffer" exception message. Debugging at that level shows that item passed down is an int not a string. Inspecting the dict that is generated from loading the file confirms that the response codes are rendered as integers. It is a rather nasty gotcha.

@the-destro: I'm usually doing something similar to the following snippet to read yaml specs from file.

import yaml
from bravado_core.spec import Spec
with open(...) as f:
    spec_dict = yaml.load(f)
spec = Spec.from_dict(spec_dict)

In this case if your responseObject has no quote around 200 we cannot do anything fancy because yaml.load(f) reads it as an integer instead of string (expected type) and so the validation will fail.

Swagger specs example are available on Swagger Spec - Response Object

    ....
    response:
        200:
            description: Dummy Response
    ....
