TURN - MiniTest Reporters

by Tim Pease
http://codeforpeople.rubyforge.org/turn

DESCRIPTION:

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.

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.

INSTRUCTION:

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/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 becuase of how bundle exec works, it was better to require a subdirectory file.

Configuration

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).

REQUIREMENTS:

  • ansi 1.1+ (for colorized output and progress bar output mode)

INSTALLATION:

Follow the ususal procedure:

$ sudo gem install turn
