TURN is a new way to view test results. With longer running tests, it can be very frustrating to see a failure (....F...) and then have to wait till all the tests finish before you can see what the exact failure was. TURN displays each test on a separate line with failures being displayed immediately instead of at the end of the tests.
If you have the 'ansi' gem installed, then TURN output will be displayed in wonderful technicolor (but only if your terminal supports ANSI color codes). Well, the only colors are green and red, but that is still color.

General usage provides better test output. Here is some sample output:
TestMyClass
test_alt PASS
test_alt_eq PASS
test_bad FAIL
./test/test_my_class.rb:64:in `test_bad'
<false> is not true.
test_foo PASS
test_foo_eq PASS
TestYourClass
test_method_a PASS
test_method_b PASS
test_method_c PASS
============================================================================
pass: 7, fail: 1, error: 0
total: 15 tests with 42 assertions in 0.018 seconds
============================================================================
Turn also provides solo and cross test modes when run from the turn commandline application.
Turn can be used from the command-line or via require. The command-line tool offers additional options for how one runs tests.
You can use the turn executable in place of the ruby interpreter.
$ turn -Ilib test/test_all.rb
This will invoke the ruby interpreter and automatically require the turn formatting library. All command line arguments are passed "as is" to the ruby interpreter.
To use the solo runner.
$ turn --solo -Ilib test/
This will run all tests in the test/ directory in a separate process. Likewise for the cross runner.
$ turn --cross -Ilib test/
This will run every pairing of tests in a separate process.
Simply require the TURN package from within your test suite.
$ require 'turn/autorun'
This will configure MiniTest to use TURN formatting for displaying test results. A better line to use, though, is the following:
begin; require 'turn/autorun'; rescue LoadError; end
When you distribute your code, the test suite can be run without requiring the end user to install the TURN package.
For a Rails application, put the require line into the 'test/test_helper.rb' script. Now your Rails tests will use TURN formatting.
Note: This changed in version 0.9. It used to be just require 'turn',
but because of how bundle exec works, it was better to require a subdirectory
file.
You can use Turn.config to adjust turn configuration.
Options are following:
tests List of file names or glob patterns of tests to run. Default: ["test/**/{test,}*{,test}.rb"]
exclude List of file names or globs to exclude from tests list. Default: []
pattern Regexp pattern that all test names must match to be eligible to run. Default: /.*/ (all)
matchcase Regexp pattern that all test cases must match to be eligible to run. Default: nil (all)
loadpath Add these folders to the $LOAD_PATH. Default: ['lib']
requires Libs to require when running tests. Default: []
format Reporter type (:pretty, :dot, :cue, :marshal, :outline, :progress). Default: :pretty
live Test against live install (i.e. Don't use loadpath option). Default: false
verbose Verbose output? Default: false
trace Number of backtrace lines to display. Default: set from ENV or nil (all)
natural Use natural language case names. Default: false
ansi Force colorized output (requires 'ansi' gem). Default: set from ENV or nil (auto)
To set option just call the desired method:
Turn.config.format = :progress
Also, you can use following environment variables to adjust settings:
backtrace Number of backtrace lines to display. Default: set from ENV or nil
ansi Force colorize output (requires 'ansi' gem).
Finally, you can include your own custom Reporter type (aka format). Turn will search for reporters in the .turn/reporters/
directory of your local project and then in your user home directory. So for example, if you specified the following:
Turn.config.format = :cool
Then Turn will look first for ./.turn/reporters/cool_reporter.rb, then ~/.turn/reporters/cool_reporter.rb.
See source code for examples of how to write your own reporters.
- ansi 1.1+ (for colorized output and progress bar output mode)
Follow the ususal procedure:
$ gem install turn
