Fog::Compute::AWS::Image not properly loaded

[tisba]

Using fog-aws 0.12.0 on ruby 2.3.1p112

I was trying to test that my code works properly when receiving a Fog::Compute::AWS::Image. As I'm using RSpec I was trying this:

instance_double(Fog::Compute::AWS::Image)

This triggers a NameError: uninitialized constant Fog::Compute::AWS::Image though, even though fog is required and used.

I could only get it working in my specs reliabaly by explicitly requiring fog/aws/models/compute/image.

In non-test code this works fine, but only because we use other APIs to fetch a list of images (it seems in those cases the class is properly loaded).

Is this a bug? If not, what is the recommended best practice in those cases?

@tisba related classes are loaded after client instantiation.Fog::Compute::AWS.new will cause models, collections, and requests to be required.

See:

• https://github.com/fog/fog-core/blob/f6ef6c3d9458bc235be57100acdced264e85e52a/lib/fog/core/service.rb#L100
• https://github.com/fog/fog-aws/blob/13fb36d/lib/fog/aws/compute.rb#L18

So the recommendation would be to set up the test/example by calling Fog::Compute::AWS.new?

Thanks, that works for me. It's not perfect, but better then requiring the file directly :)

@tisba instantiating a client is the safest solution. Depending on your usage, requiring the individual file may be sufficient.
