undefined method `get’ for #

by

RSpec doesn’t know that your spec is a controller spec, so your examples don’t have access to a get method.

RSpec 2.x assumes that everything in the controllers directory is a controller spec.

This was changed in RSpec 3:

File-type inference disabled by default

Previously we automatically inferred spec type from a file location, this was a surprising behaviour for new users and undesirable for some veteran users so from RSpec 3 onwards this behaviour must be explicitly opted into with:

RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
end

https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#file-type-inference-disabled

In the rspec-rails README:

Controller specs default to residing in the spec/controllers folder. Tagging any context with the metadata :type => :controller treats it’s examples as controller specs.

An example of setting the controller context metadata for RSpec:

describe ToolsController, :type => :controller do
    # ...
end
