Distribute your spec suite amongst your LAN via Bonjour.
- Spin up a manager on each machine that can run your specs.
- Start a dispatcher in your project directory.
- Say farewell to your long coffee breaks.
- Bonjour or DNSSD (the capability and the gem)
- Rsync (system command used)
- Rspec (officially v1.3.0)
gem install specjour
specjour on the command-line will start a manager which advertises that it's ready to run specs. By default, the manager will only use one worker to run yours specs. If you had 4 cores however, you could use
specjour --workers 4 to run 4 sets of specs at once.
Require specjour's rake tasks in your project's
Run the rake task to distribute the specs among the managers you started.
$ rake specjour
Edit your config/environment.rb
Each worker should run their specs in an isolated database. Modify the test database name in your
config/database.yml to include the following environment variable (Influenced by parallel_tests):
test: database: blog_test<%=ENV['TEST_ENV_NUMBER']%>
Each worker will attempt to clear its database tables before running any specs via
DELETE FROM <table_name>;. Additionally, test databases will be created if they don't exist (i.e.
CREATE DATABASE blog_test8 for the 8th worker) and will load your schema when it has fallen behind.
By default, a manager will listen to all projects trying to distribute specs over the network. Sometimes you'll only want a manager to respond to one specific spec suite. You can accomplish this with the
$ specjour --projects bizconf # only run specs for the bizconf project
You could also listen to multiple projects:
$ specjour --projects bizconf,workbeast # only run specs for the bizconf and workbeast projects
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
