我在我的控制器測試中得到了'應該'的未定義方法，但無法找出原因。我花了一些時間在谷歌和堆棧溢出，但我卡住了。任何幫助？RSpec未定義的方法'應該'

SimpleCov.start 'rails'

require File.expand_path("../../config/environment", __FILE__)

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.

config.expect_with :rspec do |c|
c.syntax = :expect

# ## Mock Framework
#
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#
#config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, remove the following line or assign false
# instead of true.
config.use_transactional_fixtures = false
# If true, the base class of anonymous controllers will be inferred
# automatically. This will be the default behavior in future versions of
# rspec-rails.
config.infer_base_class_for_anonymous_controllers = false
# Run specs in random order to surface order dependencies. If you find an
# order dependency and want to debug it, you can fix the order by providing
# the seed, which is printed after each run.
# --seed 1234
config.order = "random"
