# Define a task library for running RSpec contexts.
require 'rake'
require 'rake/tasklib'
module Spec
module Rake
# A Rake task that runs a set of specs.
#
# Example:
#
# Spec::Rake::SpecTask.new do |t|
# t.warning = true
# t.rcov = true
# end
#
# This will create a task that can be run with:
#
# rake spec
#
# If rake is invoked with a "SPEC=filename" command line option,
# then the list of spec files will be overridden to include only the
# filename specified on the command line. This provides an easy way
# to run just one spec.
#
# If rake is invoked with a "SPEC_OPTS=options" command line option,
# then the given options will override the value of the +spec_opts+
# attribute.
#
# If rake is invoked with a "RCOV_OPTS=options" command line option,
# then the given options will override the value of the +rcov_opts+
# attribute.
#
# Examples:
#
# rake spec # run specs normally
# rake spec SPEC=just_one_file.rb # run just one spec file.
# rake spec SPEC_OPTS="--diff" # enable diffing
# rake spec RCOV_OPTS="--aggregate myfile.txt" # see rcov --help for details
#
# Each attribute of this task may be a proc. This allows for lazy evaluation,
# which is sometimes handy if you want to defer the evaluation of an attribute value
# until the task is run (as opposed to when it is defined).
#
# This task can also be used to run existing Test::Unit tests and get RSpec
# output, for example like this:
#
# require 'rubygems'
# require 'spec/rake/spectask'
# Spec::Rake::SpecTask.new do |t|
# t.ruby_opts = ['-rtest/unit']
# t.spec_files = FileList['test/**/*_test.rb']
# end
#

# specs. Defaults to ['<the absolute path to RSpec's lib directory>']
attr_accessor :libs
# If true, requests that the specs be run with the warning flag set.
# E.g. warning=true implies "ruby -w" used to run the specs. Defaults to false.
attr_accessor :warning
# Glob pattern to match spec files. (default is 'spec/**/*_spec.rb')
# Setting the SPEC environment variable overrides this.
attr_accessor :pattern
# Array of commandline options to pass to RSpec. Defaults to [].
# Setting the SPEC_OPTS environment variable overrides this.
attr_accessor :spec_opts
# Whether or not to use RCov (default is false)
# See http://eigenclass.org/hiki.rb?rcov
attr_accessor :rcov
# Array of commandline options to pass to RCov. Defaults to ['--exclude', 'lib\/spec,bin\/spec'].
# Ignored if rcov=false
# Setting the RCOV_OPTS environment variable overrides this.
attr_accessor :rcov_opts
# Directory where the RCov report is written. Defaults to "coverage"
# Ignored if rcov=false
attr_accessor :rcov_dir
# Array of commandline options to pass to ruby. Defaults to [].
attr_accessor :ruby_opts
# Whether or not to fail Rake when an error occurs (typically when specs fail).
# Defaults to true.
attr_accessor :fail_on_error
# A message to print to stderr when there are failures.
attr_accessor :failure_message
# Where RSpec's output is written. Defaults to STDOUT.
# DEPRECATED. Use --format FORMAT:WHERE in spec_opts.
attr_accessor :out
# Explicitly define the list of spec files to be included in a
# spec. +spec_files+ is expected to be an array of file names (a
# FileList is acceptable). If both +pattern+ and +spec_files+ are
# used, then the list of spec files is the union of the two.
# Setting the SPEC environment variable overrides this.
attr_accessor :spec_files
# Use verbose output. If this is set to true, the task will print
# the executed spec command to stdout. Defaults to false.
attr_accessor :verbose
# Defines a new task, using the name +name+.
