Rspec tests not running because of initializer Yaml files - ruby

Question

I'm integrating tests with Rspec into quite a large / developed app. When I run the test I'm getting very odd errors from some of my initializers.
For example, my carrierwave.rb loads a yaml file, when I run the test command I get:
carrierwave.rb:11:in `block in <top (required)>': undefined method `[]' for nil:NilClass
which is referring to the second line of code below:
fog_config = YAML::load_file(Rails.root.join 'config/fog.yml')[Rails.env.to_s]
config.fog_directory = fog_config['directory']
Momentarily if I remove that line of code in carrierwave, omniauth starts to complain too:
omniauth.rb:4:in `block in <top (required)>': undefined method `symbolize_keys' for nil:NilClass (NoMethodError)
Again, another yaml file:
fb_config = YAML::load_file(Rails.root.join 'config/fb_app_version.yml')[Rails.env].symbolize_keys
I'm guessing the solution is to change my yaml files or include something in the tests, but I'm not sure what. Any ideas would be most appreciated, thanks.

Answer 1

It looks like you need to include test entries in the Yaml files in question.
For example, your config/fog.yml probably looks something like this:
production:
directory: the_prod_directory
other_keys: ...
development:
directory: the_dev_directory
other_keys: ...
You need to add a test key:
test:
directory: the_test_dir
other_keys: appropriate values
