Buncha logging stuff showing up in unit tests

[Joe Van Dyk]

I'm using Ruby's standard Logger to log a bunch of debug, info, and errors.

But when I run the unit tests for the classes that use the Logger, all
the logs are showing up in the test output.

Any good solutions for solving this?

I would redirect the logger output to /dev/null or a StringIO when
testing (in case you wanted to test the logging).

How do the classes know whether or not they are being tested?

Eventually, I will be using a custom Logging method that sends all the
logs to some network log daemon thingy so that all the logs are kept
on one machine.

I set $TESTING = true when testing things. The most frequent place I
use it is:

private unless $TESTING

Check out SyslogLogger in the rails_analyzer_tools gem:

http://rails-analyzer.rubyforge.org/tools/classes/SyslogLogger.html

It duck types to the base Logger class.

I set $TESTING =3D true when testing things. The most frequent place I
use it is:

private unless $TESTING

So, something like

require 'logger'
class ThisClassGetsTested
def initialize
if $TESTING
log_output =3D "/dev/null"
else
log_output =3D "some/file" # or $stdout or whatever
end
end
end

=3D=3D=3D=3D

require 'test/unit'
$TESTING =3D true
class TestTheClass < Test::Unit::TestCase
...
end

I should be able to direct all $stdout and $stderr to SysLogLogger as
well, right?

Exactly.

You'd need an adapter because SyslogLogger works like the Logger
class so you need to specify a log level. I wouldn't recommend it,
either.
