Spec::Rake::SpecTask

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 'spec/rake/spectask'
  Spec::Rake::SpecTask.new do |t|
    t.ruby_opts = ['-rtest/unit']
    t.spec_files = FileList['test/**/*_test.rb']
  end

Attributes

name[RW]

Name of spec task. (default is :spec)

libs[RW]

Array of directories to be added to $LOAD_PATH before running the specs. Defaults to [’’]

warning[RW]

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.

pattern[RW]

Glob pattern to match spec files. (default is ‘spec/**/*_spec.rb’) Setting the SPEC environment variable overrides this.

spec_opts[RW]

Array of commandline options to pass to RSpec. Defaults to []. Setting the SPEC_OPTS environment variable overrides this.

rcov[RW]

Whether or not to use RCov (default is false) See eigenclass.org/hiki.rb?rcov

rcov_opts[RW]

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.

rcov_dir[RW]

Directory where the RCov report is written. Defaults to “coverage” Ignored if rcov=false

ruby_opts[RW]

Array of commandline options to pass to ruby. Defaults to [].

fail_on_error[RW]

Whether or not to fail Rake when an error occurs (typically when specs fail). Defaults to true.

failure_message[RW]

A message to print to stderr when there are failures.

out[RW]

Where RSpec’s output is written. Defaults to $stdout. DEPRECATED. Use —format FORMAT:WHERE in spec_opts.

spec_files[RW]

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.

verbose[RW]

Use verbose output. If this is set to true, the task will print the executed spec command to stdout. Defaults to false.

ruby_cmd[RW]

Explicitly define the path to the ruby binary, or its proxy (e.g. multiruby)
