Flickraw & VCR give unexpected results - ruby-on-rails

Question

I´m using VCR to test a method which gets a list of photosets from Flickr
require 'rails_helper'
RSpec.describe Photoset, type: :model do
# ...
describe '.import' do
it "gets photosets" do
VCR.use_cassette('photosets_getList') do
expect(Photoset.import(user_id: ENV['FLICKR_TEST_USER_ID']).first).to be_a Photoset
end
end
it "sets title" do
VCR.use_cassette('photosets_getList') do
expect(Photoset.import(user_id: ENV['FLICKR_TEST_USER_ID']).first.title).to eq 'Showcase'
end
end
it "sets uid" do
VCR.use_cassette('photosets_getList') do
expect(Photoset.import(user_id: ENV['FLICKR_TEST_USER_ID']).first.uid).to eq '72157647753138397'
end
end
end
end
The method itself is pretty straight forward and uses flickraw to get the photos from
flickr.photosets.getList and them maps to Photoset objects.
class Photoset
include Mongoid::Document
include Mongoid::Timestamps
field :title, type: String
field :uid, type: String
validates_uniqueness_of :uid
belongs_to :user
# Get photosets from Flickr
# #param [Hash] opts
# #return [Enumerable]
def self.import(opts = {})
res = flickr.photosets.getList(opts)
res.map do |item|
new(
uid: item["id"],
title: item["title"]
)
end
end
end
However the specs fail intermittently as Flickraw also does a request to flickr.reflection.getMethods and
flickr.photosets.getList(opts).map { |x| x }
Sometimes returns the request methods instead of Photosets
[("flickr.activity.userComments", "flickr.activity.userPhotos", "flickr.auth.checkToken"...]
Am I using VCR wrong or is this a bug in Flickraw?

Answer 1

flickr.reflection.getMethods is called to build all the objects and methods. Flickraw does not know what methods are available when initiallzed. If you want a deterministic behavior, you can use flickraw-cached which embeds a list of all methods.
