While upgrading from rails 4.2.5 to the recently released 4.2.5.1, I have encountered this error. This error exists only for specs with a before_filter that render an invalid status, such as render file: "public/422", status: :unauthorized. I get this error for both ruby-2.2.2 and ruby-2.3.0
The error exists in the action_view resolver method, implying the @cache value is nil. However, in the initialize method it should be instantiated: @cache = Cache.new
I am still working on a reproducible sample, but am so far lost as to how @cache could be nil.
These are the config variables set in my test.rb environment
config.cache_classes = true
config.eager_load = false
config.serve_static_files = true
config.static_cache_control = 'public, max-age=3600'
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
config.action_dispatch.show_exceptions = false
config.action_controller.allow_forgery_protection = false
config.action_mailer.default_url_options = {
:host => '127.0.0.1',
:port => 3000
}
config.action_mailer.delivery_method = :test
config.active_support.test_order = :random
config.active_support.deprecation = :stderr
