Anyway, I wrote this task to run only the tests in the products/namespace I work on.

rake test:products PRODUCTS=product1,product2

Runs all unit tests in test/**/product1/*test*.rb, test/**/product2/*test*.rb

The task:

namespace :test do
  task :products do      
    raise "Usage: rake test:products PRODUCTS=product1,product2" if ENV['PRODUCTS'].blank?
    
    products = ENV['PRODUCTS'].split(/,/)
    files = []
    
    products.each do |product|
      dir = "#{RAILS_ROOT}/test/**/#{product}"
      files += FileList["#{dir}/*test*.rb"]
    end    
    
    test_task = Rake::TestTask.new("test_products") do |t|
      t.libs << "test"
      t.test_files = files
      t.verbose = true
    end
    
    task("test_products").execute           
  end
end

There is probably an easier way, but this works for me. Also I wouldn’t mind someone patching rake to accept opts style arguments, like –opt=blah, or -o blah. The ENV stuff seems really not so friendly.
