Overview

Base configuration class for Kitchen. This class exposes configuration such as the location of the Kitchen config file, instances, log_levels, etc. This object is a factory object, meaning that it is responsible for consuming the desired testing configuration in and returning Ruby objects which are used to perfom the work.

Most internal objects are created with the expectation of being immutable, meaning that internal state cannot be modified after creation. Any data manipulation or thread-unsafe activity is performed in this object so that the subsequently created objects (such as Instances, Platforms, Drivers, etc.) can safely run in concurrent threads of execution. To prevent the re-creation of duplicate objects, most created objects are memoized. The consequence of this is that once the Instance Array has been requested (with the `#instances` message), you will always be returned the same Instance objects.

Examples:

fetching all instances


Kitchen::Config.new.instances

fetching an instance by name


Kitchen::Config.new.instances.get("default-ubuntu-16.04")

fetching all instances matching a regular expression


Kitchen::Config.new.instances.get_all(/ubuntu/)

Constructor Details

#initialize(options = {}) ⇒ Config

Creates a new configuration, representing a particular testing configuration for a project.

Parameters:

  • options (Hash) (defaults to: {})

    configuration

Options Hash (options):

  • :loader (#read)

    an object that responds to `#read` with a Hash structure suitable for manipulating (default: `Kitchen::Loader::YAML.new`)

  • :kitchen_root (String)

    an absolute path to the root of a Test Kitchen project, usually containing a `.kitchen.yml` file (default `Dir.pwd`)

  • :log_root (String)

    an absolute path to the directory into which all Test Kitchen log files will be written (default: `“##kitchen_root/.kitchen/logs”`)

  • :test_base_path (String)

    an absolute path to the directory containing test suites and other testing-related files and directories (default: `“##kitchen_root/test/integration”`)

  • :log_level (Symbol)

    the log level verbosity that the loggers will use when outputing information (default: `:info`)
