How To

Run all tests

To make it easy to run all your tests, you can add a run.rb script
to your test directory. A simple example might look like:

base_dir = File.expand_path(File.join(File.dirname(FILE), “..”))
lib_dir = File.join(base_dir, “lib”)
test_dir = File.join(base_dir, “test”)

$LOAD_PATH.unshift(lib_dir)

require ‘test/unit’

exit Test::Unit::AutoRunner.run(true, test_dir)

Then it’s easy to run tests via the command line with,

$ ruby test/run.rb

Change test runner via the command line

The output format can be changed via the command line with
the --runner option. Simply tack it to the end:

ruby test/run.rb –runner emacs

Configure test-unit per-project

Test::Unit reads ~/.test-unit.yml or test-unit.yml in the current working
directory as Test::Unit’s configuration file. It can contain the following
settings:

• color scheme definitions
• test runner to be used
• test runner options
• test collector to be used

Except color scheme definitions, all of them can be specified by command
line option.

Here are sample color scheme definitions:

color_schemes:
inverted:
success:
name: red
bold: true
failure:
name: green
bold: true
other_scheme:
…

Here are the syntax of color scheme definitions:

color_schemes:
SCHEME_NAME:
EVENT_NAME:
name: COLOR_NAME
intensity: BOOLEAN
bold: BOOLEAN
italic: BOOLEAN
underline: BOOLEAN
…
…

You can use the above ‘inverted’ color scheme with the following configuration:

runner: console
console_options:
color_scheme: inverted
color_schemes:
inverted:
success:
name: red
bold: true
failure:
name: green
bold: true
