Сконфигурировать Rails для вывода production в STDOUT

For Rails 3.x, configure a logger in config/environments/test.rb:

config.logger =
config.logger.level = Logger::ERROR

This will interleave any errors that are logged during testing to STDOUT. You may wish to route the output to STDERR or use a different log level instead.

Sending these messages to both the console and a log file requires something more robust than Ruby's built-in Logger class. The logging gem will do what you want. Add it to your Gemfile, then set up two appenders in config/environments/test.rb:

logger = Logging.logger['test']
logger.level = :info
config.logger = logger
