# Rails developers have long had bad experiences with fixtures for
# several reasons, including misuse.
# 
# Misuse of fixtures is characterized by having a huge number of them, 
# requiring the developer to maintain a lot of data and creating dependencies 
# between tests. In my experience working (and rescuing) many applications, 80%
# of fixtures are only used by 20% of tests.
#
# An example of such tests is one assuring that a given SQL query with
# GROUP BY and ORDER BY conditions returns the correct result set. As expected,

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
