Does anyone know how to mock the Rails Logger then set expectations with should_receive?

Testing RSpec

Hey Guys,

I’m trying to mock the Rails Logger for the following code:

…
rescue TimeoutError => error
$logger.error("#{self.name} Timeout for #{path}: #{error}") and
return
rescue SocketError => error
$logger.error("#{self.name} SocketError for #{path}: #{error}")
and
return
rescue StandardError => error
$logger.error("#{self.name} Error for #{path}: #{error}") and
return
end
…

my failed attempt to spec:

logger = mock_model(Logger)
logger.stub(:error)
logger.should_receive(:error).with(:any_args)

Do you know of any solution for mocking this?

Also, do you think the Rails Logger is worth mocking?

Thanks very much in Advance,

You never set the $logger var to your new logger. So it wouldn’t do
anything.

You could consider partially stubbing the rails logger.
$logger.should_receive(:error)

I would say no.

In particular, sometimes logging is a domain requirement. If that’s
the case, you want to separate that kind of logging from all the log
info that Rails generates. Read

to get some info on mocking loggers.
