This configuration will make autospec run “spec/models/xyz_spec” when a file in “lib/xyz/ is modified”. No other tests are run.

Put the following code in ./.autotest:

   1  Autotest.add_hook :initialize do |at|
   2    at.clear_mappings
   3    %w{.svn .hg .git vendor}.each {|exception| at.add_exception(exception)}
   4  
   5    at.add_mapping(%r%^lib/xyz/.*\.rb$%) {
   6      at.files_matching %r%^spec/models/xyz_spec\.rb$%
   7  #
   8  # Uncomment if more tests are needed...
   9  # +   at.files_matching %r%^spec/models/xyz_spec\.rb$%
  10  #
  11    }
  12  end
