Tickle ====== Tickle spawns multiple processes and tries running your test suite in parallel for reducing the time taken to run them. Thanks to http://github.com/jasonm/parallel_test for the concept. Setup ===== To install : $ script/plugin install git://github.com/lifo/tickle.git Example ======= To run all tests : $ rake tickle # This will use 3 processes by default To run all tests using 2 processes : $ rake tickle To only run unit tests : $ rake tickle:units To run unit tests in 4 parallel processes : $ rake tickle:units tickle:functionals and tickle:integration should work as expected. Tuning ====== For best results, use tickle with Ruby Enterprise Edition and Twitter's GC settings : - http://www.rubyenterpriseedition.com/ - http://blog.evanweaver.com/articles/2009/04/09/ruby-gc-tuning/ Database Setup ============== If you're NOT USING transactional fixtures, you'll need to create 'N' new databases. Where 'N' is the maximum number of parallel processes you want to run. Assuming you want to run 2 proccesses, you'll need to provide test_1 and test_2 config settings in database.yml : test_1: adapter: mysql encoding: utf8 database: myapp_test1 pool: 5 username: root password: socket: /tmp/mysql.sock test_2: adapter: mysql encoding: utf8 database: myapp_test2 pool: 5 username: root password: socket: /tmp/mysql.sock Copyright (c) 2009 Pratik Naik, released under the MIT license
