DESCRIPTION

This plugin makes use of all the snippets provided by chef-gen-flavor-base, is meant as a reference implementation than for actual use. It demonstrates how to create a flavor with tests and serves as a good example of how to get started writing your own flavors for distribution.

There are two flavors in this gem:

example: includes all the snippets in their default form
example2: inherits from example but removes ExampleFile and ExampleTemplate from the list of snippets to use

INSTALLATION

To install the latest public gem version:

chef gem install chef-gen-flavor-example

To install from (possibly modified) source:

bundle
bundle exec rake package
chef gem install pkg/chef-gen-flavor-example-X.Y.Z.gem

USAGE

chef generate cookbook foo

This should generate the following cookbook:

$ chef generate cookbook foo
using ChefGen flavor 'example'

  * file[/home/james/foo/chefignore] action create
    - create new file /home/james/foo/chefignore
    - update content in file /home/james/foo/chefignore from none to ceda3a
    (diff output suppressed by config)

  create file /home/james/foo/README.md
  create file /home/james/foo/CHANGELOG.md
  create ignore file /home/james/foo/.gitignore
  create ignore file /home/james/foo/chefignore

    - execute the ruby block report_actions_taken
  * ruby_block[display_next_steps] action run

Now cd into the generated cookbook directory and run
  'bundle' to install Ruby gems needed for local testing and
  'bundle exec rake -T' to see which testing tasks you can run.

  You are now ready to begin writing your first recipe.

    - execute the ruby block display_next_steps

TESTING

To test, run one of:

bundle exec rake style
bundle exec rake spec
bundle exec rake features

The feature tests are written using Aruba, which is a CLI driver for Cucumber. It works off of the same feature files you may be used to using in Capybara for web app testing (though the steps are perforce quite different).

The feature tests provide a good example of how to generate a cookbook of your flavor and then test the generated artifact. For example, the test suite that comes with the example flavor tests that the Rake tasks can be listed, that the style and unit tests run cleanly, and that the kitchen suites can be listed.
