Stale Fish

This gem provides a method for keeping your fixtures in sync with their sources. This will prevent the scenario where your build is broken in production, but CI has a green build to do outdated fixture data. StaleFish also allows for FakeWeb integration and URI management.

Features

• Fixture update frequency uses the ActiveSupport relative time DSL
• Versioned configuration file & fixtures means fixtures are only updated once per project.
• Manage FakeWeb stubbed URI’s through StaleFish
• Automatic detection for Rails & Rack apps (default configuration locations)
• Test Framework agnostic (tested with Test::Unit & RSpec)
• Update all fixtures, specified fixtures, or forced update are all supported through the StaleFish.update_stale(*args) method
• Fixtures are ONLY updated when a valid HTTP request is made, if server returns anything other than 200, an error is thrown failing the tests.

How To

Simply drop in a YAML file in your application (for rails, RAILS_ROOT/config/stale_fish.yml is preferred) and issue the following commands.

A sample YAML file:

  stale:
    configuration:
      use_fakeweb: true
    yahoo:
      filepath: ./tmp/yahoo.html
      source: http://www.yahoo.com
      updated:
      frequency: 1.day
    google:
      filepath: git_commit.json
      source: http://api.github.com/post_commit/
      updated:
      frequency: 2.weeks

Specify one block for every fixture you would like to update. The frequency field takes any relative date included in the ActiveSupport library.

RSpec

For a single test add it to a before block

  describe UsersController do
    before do
      StaleFish.load_config = "#{RAILS_ROOT}/config/stale_fish.yml"
      StaleFish.update_stale("facebook", "yahoo")
    end
    ....
  end

For all tests add the following to spec_helper.rb

  Spec::Runner.configure do |config|
    ...
    before do
      StaleFish.load_config = "#{RAILS_ROOT}/config/stale_fish.yml"
      StaleFish.update_stale
    end
    ....
  end

Test::Unit

For all tests add the following to test_helper.rb

  class Test::Unit::TestCase
    ...
    self.use_transactional_fixtures = true
    self.use_instantiated_fixtures  = false
    ...
    setup do
      StaleFish.load_config = "#{RAILS_ROOT}/config/stale_fish.yml"
      StaleFish.update_stale
    end
    ...
  end
