Class Method Details

.database_cleaner(config) ⇒ Object

Setups database cleaner to use strategy depending on metadata. By default it uses ‘:transaction` for all examples and `:truncation` for features and examples with `concurrent: true`.

Other types can be tuned with ‘config.cleaner_strategy` hash & `config.cleaner_strategy.default`.

def database_cleaner(config)
  config.use_transactional_fixtures = false
  config.add_setting :cleaner_strategy
  config.cleaner_strategy = {feature: :truncation}
  config.cleaner_strategy.default = :transaction
  config.around do |ex|
    strategy = ex.metadata[:concurrent] && :truncation
    strategy ||= config.cleaner_strategy[ex.metadata[:type]]
    options = strategy == :truncation ? {except: %w(spatial_ref_sys)} : {}
    DatabaseCleaner.strategy = strategy, options
    DatabaseCleaner.cleaning { ex.run }
  end
end

.debug(config, filter: {debug: true}, debugger: :pry) ⇒ Object

Runs debugger after each failed example. Uses ‘pry` by default and runs only for examples with `:debug` tag. This can be configured with `:debugger` and `:filter` options respectively:

configurator.debug(config, filter: {my_tag: :val}, debugger: true)
# to disable filter:
configurator.debug(config, filter: nil)

  config.after(filter) do |ex|
    if ex.exception
      debugger == :pry ? binding.pry : self.debugger # rubocop:disable Debugger
      ex.exception # noop
    end
  end
end

.redis(config) ⇒ Object

Setups redis to flush db after suite and before each example with ‘flush_redis: :true`. `Rails.redis` client is used by default. Can be tuned with `config.redis`.
