# Ties everything together. If you subclass and add your own
# test methods, it takes care of making them into tests and
# wrapping those tests into a suite. It also does the
# nitty-gritty of actually running an individual test and
# collecting its results into a Test::Unit::TestResult object.
#
# You can run two hooks before/after a TestCase run.
#
# Example:
#
# class TestMyClass < Test::Unit::TestCase
# class << self
# def startup
# ...
# end
#
# def shutdown
# ...
# end
# end
#
# def setup
# ...
# end
#
# def cleanup
# ...
# end
#
# def teardown
# ...
# end
#
# def test_my_method1
# ...
# end
#
# def test_my_method2
# ...
# end
# end
#
# Here is a call order:
#
# 1. startup
# 1. setup
# 1. test_my_method1
# 1. cleanup
# 1. teardown
# 1. setup
# 1. test_my_method2
# 1. cleanup
# 1. teardown
# 1. shutdown
#
# You can set an attribute to each test.
#
# Example:
#
# class TestMyClass < Test::Unit::TestCase
# attribute :speed, :fast
# def test_my_fast_method
# # You can get the attribute via `self[]`
# self[:speed] # => :fast
# ...
# end
#
# attribute :speed, :slow
# def test_my_slow_method
# self[:speed] # => :slow
# ...
