anachronic

Directory content snapshots w/ comparison functionality to track filename & existence changes in testing. Developed for cucumber & rspec.

Enables easy implementation of this kind of cucumber scenario:

Scenario: completely delete an image
  Given I record the state of "public/system"
  And a site image exists
  Then the file contents of "public/system" should have changed
  When I go to the site_image's page
  And I press "Delete Image"
  Then the site image should be deleted
  When I go to the site_images page
  Then I should not see "Metal Box"
  Then the file contents of "public/system" should be as they were

Where the steps of interest are:

Given I record the state of "public/system"
Then the file contents of "public/system" should have changed
Then the file contents of "public/system" should be as they were

And are as simple as:

Given /^I record the state of "([^\"]*)"$/ do |path|
  @snapshot = Anachronic::Directory.new(path)
end

Then /^the file contents of "([^\"]*)" should have changed$/ do |path|
  @snapshot.name_diff(Anachronic::Directory.new(path)).should_not be_empty
end

Then /^the file contents of "([^\"]*)" should be as they were$/ do |path|
  diff = @snapshot.name_diff(Anachronic::Directory.new(path))
  diff.should be_empty, "#{diff.inspect}"
end

Where this code sits in vendor/plugins/anachronism.

Gem to follow, when I get it to work.

Missing Functionality / Planned Features

• Does not detect file size, timestamp, or content changes
• Does not show whether files were +'d or -'d (think diff)

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history.
  (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
