Rails - Jul 2007 - test:uncommitted didn't work, so I wrote test:svn_recent

Railsters:

Put this into a *.rake file, and invoke it from a command line as
"rake test:svn_recent":

require ''fileutils''

task ''test:svn_recent'' do
  `svn status`.
    split("\n").
      map{|f| f =~ /^M\s+(.*_test.rb)/; $1 }.
        compact.
          each do |uncommitted|
            FileUtils.touch uncommitted
          end

  Rake::Task[''test:recent''].invoke
end

It finds every SVN file with a status of M (due to Subversion''s stated
goal to support absurdly easy grep-based scripting), and touches this
file. Then it invokes the normal test:recent run, which adds files to
the test list if their modification time is newer than 10 minutes ago.

For a good time, we could also add the ability to find every modified
source file, find its matching *_test.rb, and trigger it. That
behavior is allegedly in test:recent too, but I have never seen it
working. It should be very easy to add to this system.

Here''s an upgrade to my former attempt, this time using the
rake-internal
mechanisms, instead of touching files.

Put this into a *.rake file, and invoke it from a command line as
"rake test:svn_modified":

namespace :test do
  Rake::TestTask.new(:svn_modified => "db:test:prepare") do |t|
    t.libs << ''test''
    t.verbose = true

    t.test_files = `svn status test`.
                     split("\n").
                       map{|f| f =~ /^M\s+(.*_test.rb)/; $1 }.
                         compact.
                           uniq
  end
end

It finds every SVN file in the test folder with a status of M (due to 
Subversion''s stated
goal to support absurdly easy grep-based scripting). Then it passes these 
files to the ''test'' task.

This works better than test:recent because (even while practicing Continuous 
Integration), files may stay modified for longer than 10 minutes between 
integrations.
