# RSpec::LoggingHelper

### Public Instance Methods

capture_log_messages( opts = {} ) click to toggle source

Capture log messages from the Logging framework and make them available via a @log_output instance variable. The @log_output supports a readline method to access the log messages.

    # File lib/rspec/logging_helper.rb, line 9
    def capture_log_messages( opts = {} )
      from = opts.getopt(:from, 'root')
      to = opts.getopt(:to, '__rspec__')
      exclusive = opts.getopt(:exclusive, true)

      appender = Logging::Appenders[to] || Logging::Appenders::StringIo.new(to)
      logger = Logging::Logger[from]
      if exclusive
        logger.appenders = appender
      else
        logger.add_appenders(appender)
      end

      before(:all) do
        @log_output = Logging::Appenders[to]
      end

      before(:each) do
        @log_output.reset
      end
    end
