Test with fork
Tork runs your tests as they change, in parallel:
Absorbs test execution overhead into a master process.
Forks to inherit overhead and run test files in parallel.
Avoids running unchanged tests inside changed test files.
No configuration necessary: simply run
torkto start testing now!
Runs test files in parallel using fork for multi-core/CPU utilization.
Tests changes your Ruby application for rapid TDD: avoids running (1) unchanged test files and (2) unchanged tests inside changed test files.
Supports MiniTest, Test::Unit, RSpec, and any testing framework that (1) exits with a nonzero status to indicate test failures and (2) is loaded by your application's
Logs the output from your tests into separate files: one log per test.
Configurable through Ruby scripts in your current working directory.
You can override the modular
tork*programs with your own in $PATH.
You can remotely control other
tork*programs using tork-remote(1).
Following UNIX philosophy, Tork is composed of simple text-based programs that do one thing well. As a result, you can even create your own user interface for Tork by wrapping the tork-driver(1) program appropriately!
- tork(1) is an interactive command-line user interface for tork-driver(1)
- tork-runner(1) runs your test suite once, non-interactively, and then exits
- tork-herald(1) monitors current directory tree and reports changed files
- tork-driver(1) drives the engine according to the herald's observations
- tork-engine(1) tells master to run tests and keeps track of test results
- tork-master(1) absorbs test execution overhead and forks to run your tests
- tork-remote(1) remotely controls any Tork program running in the same
- tork-notify(1) notifies you when previously passing tests fail or vice versa
When the herald observes that files in or beneath the current directory have been written to, it tells the driver, which then commands the master to fork a worker process to run the tests affected by those changed files. This is all performed automatically. However, to run a test file manually, you can:
Simply save the file! When you do, Tork tries to figure out which tests inside your newly saved test file have changed (using diff and regexps) and then attempts to run just those. To make it run all tests in your saved file, simply save the file again without changing it.
tfollowed by a space and the file you want to run into tork(1):
# run all of test/some_test.rb t test/some_test.rb # run lines 4, 33, and 21 of test/some_test.rb t test/some_test.rb 4 33 21
["run_test_file"]message to tork-engine(1) using tork-remote(1):
# run all of test/some_test.rb echo run_test_file test/some_test.rb | tork-remote tork-engine # run lines 4, 33, and 21 of test/some_test.rb echo run_test_file test/some_test.rb 4 33 21 | tork-remote tork-engine
Alternatively, you can use tork-runner(1) to run your test suite in one shot
and then exit with a nonzero status if tests failed, similar to
gem install tork
Ruby 1.8.7 or 1.9.3 or newer.
Operating system that supports POSIX signals and the
fork()system call. To check if your system qualifies, launch irb(1) and enter the following:
Process.respond_to? :fork # must be true Signal.list.key? 'TERM' # must be true Signal.list.key? 'KILL' # must be true
To make the tork-herald(1) program's filesystem monitoring more efficient:
gem install rb-inotify # linux gem install rb-fsevent # macosx
git clone git://github.com/sunaku/tork cd tork bundle install bundle exec tork --help # run it directly bundle exec rake --tasks # packaging tasks
At the command line
You can add line editing, history, and filename completion:
rlwrap -c tork
You can control tork(1) interactively from another terminal:
tork-remote tork-engine # type your commands here, one per line. # press Control-D to exit tork-remote(1)
You can also do the same non-interactively using a pipeline:
# run lines 4, 33, and 21 of test/some_test.rb echo run_test_file test/some_test.rb 4 33 21 | tork-remote tork-engine
You can monitor your test processes from another terminal:
watch 'pgrep -f ^tork | xargs -r ps uf'
bundler configuration helper loads a Bundler bundle into tork-master(1).
default configuration helper does this for you automatically if there is
Gemfile.lock file present in your current working directory.
As a result, you don't need to add Tork to your
Gemfile just to run tests!
Instead, installing Tork as a Ruby gem outside of your bundle is sufficient.
Try it: go into any bundled application and call
tork to run its test suite.
MiniTest 1.3.2 and newer contain a bug where
minitest/autorun won't run any
tests if someone calls
Kernel#exit explicitly or simply loads a library
(such as RSpec) which makes the call implicitly. Use Tork 19.0.2+ to avoid
this problem or apply this patch to the minitest library to fix the problem.
RSpec 2.9.0 and newer contain a bug where RSpec's autorun helper won't run any
specs if someone calls
Kernel#exit explicitly or simply loads a library
(such as Test::Unit) which makes the call implicitly. Use Tork 19.0.2+ to
avoid this problem or apply this patch to the rspec-core library to fix the problem.
RSpec 2.8.0 and older contain a bug where a nonzero exit status (caused
by an uncaught exception) is overridden by RSpec's
Kernel#at_exit handler to
be zero, thereby falsely indicating that a spec had passed. This patch fixes the problem.
For Rails 3 or newer, use the
rails configuration helper before the
spec helpers. Otherwise your test helper will load Rails before the
rails configuration helper has a chance to disable class caching!
For older Rails, make sure your
config/environments/test.rb file contains:
config.cache_classes = false
For older Rails, to use SQLite3 as your test database, install the in-memory database adapter. Otherwise, you might face these errors:
SQLite3::BusyException: database is locked
cannot start a transaction within a transaction
For older Rails, to use SQLite3 as your test database along with browser-based acceptance testing frameworks such as Capybara, see http://www.spacevatican.org/2012/8/18/threading-the-rat/
Tork looks for a configuration directory named
.tork/ inside its working
directory. The configuration directory contains specially-named Ruby scripts,
within which you can query and modify the settings for various tork programs.
See the "FILES" sections in the manual pages of tork programs for details.
Note that tork does not automatically reload changes from your configuration directory. Consequently, you must restart tork if your configuration changes.
