Defined in:
lib/dtr/raketasks.rb

Overview

Create tasks that run a set of tests with DTR injected. The TestTask will create the following targets:

[:dtr]: 

Create a task that runs a set of tests by DTR master.

[DTR::PackageTask]: 

Create a packaging task that will package the project into
distributable files for running test on remote machine.
All test files should be included.

Example:

require 'dtr/raketasks'

DTR::TestTask.new do |t|
  t.libs << "test"
  t.test_files = FileList['test/test*.rb']
  t.verbose = true
  t.processes = 1 # default is 1
  t.package_files.include("lib/**/*") # default is FileList["**/*"]
  t.package_files.include("test/**/*")
end

This task inherits from Rake::TestTask, and adds 2 DTR specific options: processes and package_files.
