ruby - NameError: uninitialized constant when trying to execute rails tests -
in rails 3.2.13 app i'm writing right have model called business. model getting fatter , fatter, decided split in two, extracting code related availability rails concern named availability, stored @ models/concerns/business
class business module availability extend activesupport::concern availability_open = 1 availability_closed = -1 availability_complete = -2 ... as concerns not enabled in rails default, i've put following line in config/application.rb in order autoload them:
config.autoload_paths += %w(#{config.root}/app/models/concerns) the problem that, after split, tests have stopped working, returning nameerror: uninitialized constant availability error. suppose need require concern somehow in tests, haven't managed yet, , don't understand why concern needed in tests doesn't make use of it.
the following stack trace returned after running tests:

it seems errors happen when executing tests caused fixtures. if comment fixtures :all loading on test_helper.rb , create simple test asserts true, test pass, doesn't when fixtures loaded.
finally found reason why tests failed error. referencing constant declared in availability concern using availabiliy:: , instead of using business::. also, tests not in sync current code, made finding bug lot more difficult should. replacing references availability business solved problem. lesson here is: keep application , testing code in sync.
thank lichtamberg kind support.
