TURN - Test::Unit Reporter (New)

DESCRIPTION:

TURN is a new way to view Test::Unit 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.

FEATURES:

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.

SYNOPSIS:

Turn can be using from the command-line or via require. The command-line tool offers additional options for how one runs tests.

Command Line

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.

Require

Simply require the TURN package from within your test suite.

$ require 'turn'

This will configure Test::Unit to use TURN formatting for displaying test restuls. A better line to use, though, is the following:

begin; require 'turn'; 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.

RAILS/BUNDLER USERS

Bundler automatically requires everything listed in your Gemfile, e.g. when using bundle exec. This means turn will get automatically required too, which in turn means the Turn's test autorunner is doing to kick in. Obviously we don't want that to happen unless we are actually running tests.

Turn was created well before Bundler existed, and the use of require 'turn' as the autorunner was the obvious convenience. Unfortunately Bundler's choice to force require all requirements by defualt can have unexpected consequences, as is the case here.

Thankfully there is a work around. In your Gemfile add:

gem 'turn', :require => false

The :require option will prevent Turn from trying to autorun tests.

In the future we will change turn to use reuqire 'turn/autorun' instead, but that will require a lot of people to update a lot of tests, so it's not something to do lightly. Full change over will wait until the 1.0 release. In the mean time Turn will just put out a warning.
