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.
