Configuration

• in spec/rails_helper.rb

# require database cleaner at the top level
require 'database_cleaner'

# ... (this means existing code in the file)

# config.raise_errors_for_deprecations!
config.infer_spec_type_from_file_location!

# configure shoulda matchers to use rspec as the test framework and full matcher libraries for rails
Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    # Choose a test framework:
    with.test_framework :rspec
    # Or, choose the following (which implies all of the above):
    with.library :rails
  end
end

# ...

RSpec.configuration do |config|
  # [...]
  # add `FactoryGirl` methods
  config.include FactoryGirl::Syntax::Methods

  # start by truncating all the tables but then use the faster transaction strategy the rest of the time.
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
    DatabaseCleaner.strategy = :transaction
  end

  # start the transaction strategy as examples are run
  config.around(:each) do |example|
    DatabaseCleaner.cleaning do
      example.run
    end
  end
  # [...]
end

• When using Capybara use see this and add the code

• in config/application.rb add:

    config.generators do |g|
      g.test_framework :rspec,
                       fixtures: true,
                       view_specs: false,
                       helper_specs: true,
                       routing_specs: false,
                       controller_specs: true,
                       request_specs: false
      g.fixture_replacement :factory_girl, dir: "spec/factories"
    end

now in the command line run

$ rspec
