autowatchr¶ ↑

Provides some autotest-like behavior for watchr (github.com/mynyml/watchr).

Installation¶ ↑

gem install autowatchr --source http://gemcutter.org

Current features¶ ↑

• Auto-watches test and lib files using the autotest layout

• Optionally run only failing-tests

• Optionally run entire suite after all tests pass

Todo¶ ↑

• Cucumber support

• Expose algorithm to map test classes to test files

• Add INT signal trapping

Example use¶ ↑

Create a .watchr file for your project and simply declare an Autowatchr block within it:

# test/test.watchr
require 'autowatchr'

Autowatchr.new(self) do |config|
  config.ruby = 'jruby'
  config.lib_dir = 'leet_lib'
  config.test_dir = 'leet_test'
end

Your tests can then be run with:

$ watchr test/test.watchr

Configuration options¶ ↑

• command

  • An ERB template for the command

  • Default: "<%= ruby %> -I<%= include %> <% list_of_requires.each { |lib| %>-r<%= lib %> <% } %><%= predicate %>"

• ruby

  • The ruby executable to use

  • Default: "ruby"

• include

  • Paths to include (with -I)

  • Default: ".:#{self.lib_dir}:#{self.test_dir}"

• require

  • Libraries to include (with -r)

  • Can either be a string or an array (Ex: config.require = %w{rubygems active_support})

  • Default: nil

• lib_dir

  • The lib path, where your library lives

  • Default: "lib"

• test_dir

  • The test path, where your tests live

  • Default: "test"

• lib_re

  • The regexp to use for discovering library files

  • Default: '^%s./.\.rb$' % self.lib_dir

• test_re

  • The regexp to use for discovering test files

  • Default: '^%s./test_.\.rb$' % self.test_dir

• test_file

  • The filename pattern for correlating test files with lib files. The %s will be substituted for the basename of the lib file.

  • Default: 'test_%s.rb'

• failing_only

  • Run only failing tests the next time a test file is run

  • Default: true

• run_suite

  • Run entire test suite after failing tests pass

  • Default: true

All of the config options are optional. You can also pass in a hash instead of a block. Also see: test.watchr.

Using with RSpec¶ ↑

Autowatchr can easily be configured to work with the standard RSpec file hierarchy:

# spec/spec.watchr
require 'autowatchr'

Autowatchr.new(self) do |config|
  config.test_dir = 'spec'
  config.test_re = "^#{config.test_dir}/(.*)_spec\.rb$"
  config.test_file = '%s_spec.rb'
end

Be sure you have spec_helper.rb required in every spec file, or else put it in your .watchr file.

Prettier Results¶ ↑

Autowatchr is compatible with the Watchr redgreen gem. Install ‘mynyml-redgreen’ and simply require it in your .watchr file.
