Instance Method Details

#stub_bearcat(endpoint, prefix: nil, method: :auto, **kwargs) ⇒ Object

Helper method to Stub Bearcat requests. Automagically parses the Bearcat method source to determine the correct URL to stub. Accepts optional keyword parameters to interpolate specific values into the URL. Returns a mostly-normal Webmock stub (:to_return has been overridden to allow :body to be set to a Hash)
