Module: Beaker::DSL::Helpers

Included in:
Beaker::DSL
Defined in:
lib/beaker/dsl/helpers.rb

Overview

This is the heart of the Puppet Acceptance DSL. Here you find a helper to proxy commands to hosts, more commands to move files between hosts and execute remote scripts, confine test cases to certain hosts and prepare the state of a test case.

To mix this is into a class you need the following:

  • a method hosts that yields any hosts implementing Host‘s interface to act upon.

  • a method logger that yields a logger implementing Logger‘s interface.

  • the module Roles that provides access to the various hosts implementing Host‘s interface to act upon

  • the module Wrappers the provides convenience methods for Command creation

def apply_manifest(manifest, opts = {}, &block)
  apply_manifest_on(default, manifest, opts, &block)
end

#apply_manifest_on(host, manifest, opts = {}, &block) ⇒ Object

Runs ‘puppet apply’ on a remote host, piping manifest through stdin

Parameters:

  • host (Host) —

    The host that this command should be run on

  • manifest (String) —

    The puppet manifest to apply

  • opts (Hash{Symbol=>String}) (defaults to: {}) —

    Options to alter execution.

  • block (Block) —

    This method will yield to a block of code passed by the caller; this can be used for additional validation, etc.

Options Hash (opts):

  • :silent (Boolean) — default: false —

    Do not produce log output

  • :acceptable_exit_codes (Array<Fixnum>) — default: [0] —

    An array (or range) of integer exit codes that should be considered acceptable. An error will be thrown if the exit code does not match one of the values in this list.

  • :environment (Hash{String=>String}) — default: {} —

    These will be treated as extra environment variables that should be set before running the command.

  • :parseonly (Boolean) — default: false —

    If this key is true, the “–parseonly” command line parameter will be passed to the ‘puppet apply’ command.

  • :trace (Boolean) — default: false —

    If this key exists in the Hash, the “–trace” command line parameter will be passed to the ‘puppet apply’ command.

  • :catch_failures (Boolean) — default: false —

    By default “puppet –apply” will exit with 0, which does not count as a test failure, even if there were errors applying the manifest. This option enables detailed exit codes and causes a test failure if “puppet –apply” indicates there was a failure during its execution.

def apply_manifest_on(host, manifest, opts = {}, &block)
  on_options = {:stdin => manifest + "\n"}
  on_options[:acceptable_exit_codes] = opts.delete(:acceptable_exit_codes)
  args = ["--verbose"]
  args << "--parseonly" if opts[:parseonly]
  args << "--trace" if opts[:trace]

  if opts[:catch_failures]
    args << '--detailed-exitcodes'

    # From puppet help:
    # "... an exit code of '2' means there were changes, an exit code of
    # '4' means there were failures during the transaction, and an exit
    # code of '6' means there were both changes and failures."
    # We're after failures specifically so catch exit codes 4 and 6 only.
    on_options[:acceptable_exit_codes] |= [0, 2]
  end

  # Not really thrilled with this implementation, might want to improve it
  # later.  Basically, there is a magic trick in the constructor of
  # PuppetCommand which allows you to pass in a Hash for the last value in
  # the *args Array; if you do so, it will be treated specially.  So, here
  # we check to see if our caller passed us a hash of environment variables
  # that they want to set for the puppet command.  If so, we set the final
  # value of *args to a new hash with just one entry (the value of which
  # is our environment variables hash)
  if opts.has_key?(:environment)
    args << { :environment => opts[:environment]}
  end

  on host, puppet( 'apply', *args), on_options, &block

#check_for_package(host, package_name) ⇒ Boolean

Check to see if a package is installed on a remote host

Parameters:

  • host (Host) —

    A host object

  • package_name (String) —

    Name of the package to check for.

Returns:

  • (Boolean) —

    true/false if the package is found

#confine(type, criteria, host_array = nil, &block) ⇒ Array<Host>

Note:

This will modify the TestCase#hosts member in place unless an array of hosts is passed into it and TestCase#logger yielding an object that responds like Logger#warn, as well as Outcomes#skip_test, and optionally TestCase#hosts.

Limit the hosts a test case is run against

Examples:

Basic usage to confine to debian OSes.

confine :to, :platform => 'debian'

Confining to anything but Windows and Solaris

confine :except, :platform => ['windows', 'solaris']

Using additional block to confine to Solaris global zone.

confine :to, :platform => 'solaris' do |solaris|
  on( solaris, 'zonename' ) =~ /global/
end

Parameters:

  • type (Symbol) —

    The type of confinement to do. Valid parameters are :to to confine the hosts to only those that match criteria or :except to confine the test case to only those hosts that do not match criteria.

  • criteria (Hash{Symbol,String=>String,Regexp,Array<String,Regexp>}) —

    Specify the criteria with which a host should be considered for inclusion or exclusion. The key is any attribute of the host that will be yielded by Host#[]. The value can be any string/regex or array of strings/regexp. The values are compared using [Enumerable#any?] so that if one value of an array matches the host is considered a match for that criteria.

  • host_array (Array<Host>) (defaults to: nil) —

    This creatively named parameter is an optional array of hosts to confine to. If not passed in, this method will modify TestCase#hosts in place.

  • block (Proc) —

    Addition checks to determine suitability of hosts for confinement. Each host that is still valid after checking criteria is then passed in turn into this block. The block should return true if the host matches this additional criteria.

Returns:

  • (Array<Host>) —

    Returns an array of hosts that are still valid targets for this tests case.

Raises:

  • (SkipTest) —

    Raises skip test if there are no valid hosts for this test case after confinement.

#stub_hosts(ip_spec) ⇒ Object

This method accepts a block and using the puppet resource ‘host’ will setup host aliases before and after that block on the default host

Examples:

Stub puppetlabs.com on the default host to 127.0.0.1

stub_hosts('puppetlabs.com' => '127.0.0.1')

end

#stub_hosts_on(machine, ip_spec) ⇒ Object

This method accepts a block and using the puppet resource ‘host’ will setup host aliases before and after that block.

A teardown step is also added to make sure unstubbing of the host is removed always.

Examples:

Stub puppetlabs.com on the master to 127.0.0.1

stub_hosts_on(master, 'puppetlabs.com' => '127.0.0.1')

Parameters:

  • machine (String) —

    the host to execute this stub

  • ip_spec (Hash{String=>String}) —

    a hash containing the host to ip mappings

end

#with_puppet_running_on(host, conf_opts, testdir = host.tmpdir(File.basename(@path)), &block) ⇒ Object

Test Puppet running in a certain run mode with specific options. This ensures the following steps are performed:

  1. The pre-test Puppet configuration is backed up

  2. A new Puppet configuraton file is layed down

  3. Puppet is started or restarted in the specified run mode

  4. Ensure Puppet has started correctly

  5. Further tests are yielded to

  6. Revert Puppet to the pre-test state

  7. Testing artifacts are saved in a folder named for the test

Examples:

A simple use case to ensure a master is running

with_puppet_running_on( master ) do
    ...tests that require a master...
end

Fully utilizing the possiblities of config options

with_puppet_running_on( master,
                        :main => {:logdest => '/var/blah'},
                        :master => {:masterlog => '/elswhere'},
                        :agent => {:server => 'localhost'} ) do

  ...tests to be ran...
end

Parameters:

  • host (Host) —

    One object that act like Host

  • conf_opts (Hash{Symbol=>String}) —

    Represents puppet settings. Sections of the puppet.conf may be specified, if no section is specified the a puppet.conf file will be written with the options put in a section named after [mode]

    There is a special setting for command_line arguments such as –debug or –logdest, which cannot be set in puppet.conf. For example:

    :commandline_args => ‘–logdest /tmp/a.log’

    These will only be applied when starting a FOSS master, as a pe master is just bounced.

  • testdir (File) (defaults to: host.tmpdir(File.basename(@path))) —

    The temporary directory which will hold backup configuration, and other test artifacts.

  • block (Block) —

    The point of this method, yields so tests may be ran. After the block is finished puppet will revert to a previous state.

Raises:

  • (ArgumentError)
