undefined method `use_transactional_fixtures
guard, rspec, ruby-on-rails, tdd
Solution
Might be because you are not using ActiveRecord (e.g you are using MongoId) and if that's the case you need to comment out *config.use_transactional_fixtures* in spec_helper
spec_helper.rb
# 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 = true
Problem
I was following a long with this tutorial on how to test rails apps and I came across this error: ``` /home/***/***/***/spec/spec_helper.rb:27:in `block in <top (required)>': undefined method `use_transactional_fixtures=' for #<RSpec::Core::Configuration:0x9fe8824> (NoMethodError) ``` My gems are as follows: ``` gem "rspec-rails", :group => [:test, :development] group :test do gem "factory_girl_rails" gem "capybara" gem "guard-rspec" end ``` and my config file is as follows: ``` # This file is copied to spec/ when you run 'rails generate rspec:install' ENV["RAILS_ENV"] ||= 'test' require File.expand_path("../../config/environment", __FILE__) require 'rspec/rails' require 'rspec/autorun' require 'capybara/rspec' # Requires supporting ruby files with custom matchers and macros, etc, # in spec/support/ and its subdirectories. Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} RSpec.configure do |config| # ## 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 = true # 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" end ``` so why am I getting this error when ever guard is run?
