-module Rake
-
- # Create a task that runs a set of tests.
- #
- # Example:
- #
- # Rake::TestTask.new do |t|
- # t.libs << "test"
- # t.test_files = FileList['test/test*.rb']
- # t.verbose = true
- # end
- #
- # If rake is invoked with a "TEST=filename" command line option,
- # then the list of test files will be overridden to include only the
- # filename specified on the command line. This provides an easy way
- # to run just one test.
- #
- # If rake is invoked with a "TESTOPTS=options" command line option,
- # then the given options are passed to the test process after a
- # '--'. This allows Test::Unit options to be passed to the test
- # suite.
- #
- # Examples:
- #
- # rake test # run tests normally
- # rake test TEST=just_one_file.rb # run just one test file.
- # rake test TESTOPTS="-v" # run in verbose mode
- # rake test TESTOPTS="--runner=fox" # use the fox test runner
- #

- # Name of test task. (default is :test)
- attr_accessor :name

- # tests. (default is 'lib')

- # True if verbose test output desired. (default is false)
- attr_accessor :verbose
-
- # Test options passed to the test suite. An explicit
- # TESTOPTS=opts on the command line will override this. (default
- # is NONE)
- attr_accessor :options
-
- # Request that the tests be run with the warning flag set.
- # E.g. warning=true implies "ruby -w" used to run the tests.

- # Style of test loader to use. Options are:
- #
- # * :rake -- Rake provided test loading script (default).
- # * :testrb -- Ruby provided test loading script.
