Thanks to the
Rails Envy Podcast for mentioning my note on autotest configuration. Another aspect I enjoy about using the verbose flag is that autotest tells you exactly what has triggered the re-test. Kind of a fun way to look under the hood of your testing system:
[["app/controllers/admin/users_controller.rb", Wed Jan 23 14:06:10 -0600 2008]]
/usr/local/bin/ruby -S script/spec -O spec/spec.opts spec/controllers/other_inboxes_controller_spec.rb spec/controllers/admin/users_controller_spec.rb
If you like that, you might also be interested in the autotest timestamp plugin, which stamps autotest runs like so:
# Waiting at 2008-01-23 14:06:17
All you have to do is uncomment this line in your ~/.autotest file:
require 'autotest/timestamp'

I followed a tip from
David Chelimsky's blog and began running autotest with the -v flag for verbosity. When you first run it, you get a bunch of lines like this:
Dunno! spec/other_inbox_spec_helpers.rb
Dunno! app/views/layouts/main/_footer.erb
Which show all the files for which autotest doesn't have a mapping. With
ZenTest 3.8.0 out, it's easy to add mappings (which tell autotest which tests to run when a matching file changes) and exceptions (which tell autotest which files to ignore). You can also set up .autotest files for particular projects, or for your whole development machine (~/.autotest).
Here's an example of a per-project .autotest I use, sitting in the Rails root directory. I've got a custom spec helper and I want to rerun all my tests if this file ever changes:
Autotest.add_hook :initialize do |at|
%w{ domain_regexp perfdata coverage reports }.each { |exception| at.add_exception(exception) }
at.add_mapping(/spec\/app_spec_helper.rb/) do |_, m|
at.files_matching %r%^spec/(controllers|helpers|lib|models|views)/.*\.rb$%
end
end
And here's part of my site-wide .autotest file, mostly cribbed from David's blog, where I'm ignoring other kinds of cruft that pile up in projects. Also note the mapping for spec/defaults.rb, a file I commonly setup in my specs containing default parameters for different models.
Autotest.add_hook :initialize do |at|
%w{.hg .git .svn stories tmtags Rakefile Capfile README spec/spec.opts spec/rcov.opts vendor/gems autotest svn-commit .DS_Store }.each {|exception|at.add_exception(exception)}
at.add_mapping(/spec\/defaults.rb/) do |f, _|
at.files_matching %r%^spec/(controllers|helpers|lib|models|views)/.*\.rb$%
end
end
