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 options that provides an options hash, see Options::OptionsHash

  • 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

#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.

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

    The list of exit codes that will NOT raise an error when found upon command completion. If provided, these values will be combined with those used in :catch_failures and :expect_failures to create the full list of passing exit codes.

  • :environment (Hash) —

    Additional environment variables to 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 or changes when 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.

  • :catch_changes (Boolean) — default: false —

    This option enables detailed exit codes and causes a test failure if ‘puppet –apply` indicates that there were changes or failures during its execution.

  • :expect_changes (Boolean) — default: false —

    This option enables detailed exit codes and causes a test failure if ‘puppet –apply` indicates that there were no resource changes during its execution.

  • :expect_failures (Boolean) — default: false —

    This option enables detailed exit codes and causes a test failure if ‘puppet –apply` indicates there were no failure during its execution.

  • :future_parser (Boolean) — default: false —

    This option enables the future parser option that is available from Puppet verion 3.2 By default it will use the ‘current’ parser.

  • :noop (Boolean) — default: false —

    If this option exists, the the “–noop” command line parameter will be passed to the ‘puppet apply’ command.

  • :modulepath (String) —

    The search path for modules, as a list of directories separated by the system path separator character. (The POSIX path separator is ‘:’, and the Windows path separator is ‘;’.)

#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.

#on(host, command, opts = {}, &block) ⇒ Result

The primary method for executing commands on some set of hosts.

Examples:

Most basic usage

on hosts, 'ls /tmp'

Allowing additional exit codes to pass

on agents, 'puppet agent -t', :acceptable_exit_codes => [0,2]

Using the returned result for any kind of checking

if on(host, 'ls -la ~').stdout =~ /\.bin/
  ...do some action...
end

Using TestCase helpers from within a test.

agents.each do |agent|
  on agent, 'cat /etc/puppet/puppet.conf' do
    assert_match stdout, /server = #{master}/, 'WTF Mate'
  end
end

Using a role (defined in a String) to identify the host

on "master", "echo hello"

Using a role (defined in a Symbol) to identify the host

on :dashboard, "echo hello"

Parameters:

  • host (Host, Array<Host>, String, Symbol) —

    One or more hosts to act upon, or a role (String or Symbol) that identifies one or more hosts.

  • command (String, Command) —

    The command to execute on host.

  • block (Proc) —

    Additional actions or assertions.

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

    Options to alter execution.

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.

Returns:

  • (Result) —

    An object representing the outcome of command.

Raises:

  • (FailTest) —

    Raises an exception if command obviously fails.

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

Return a set of hosts that meet the given criteria

Parameters:

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

    Specify the criteria with which a host should be considered for inclusion. 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 selection. 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>) —

Examples:

Most basic usage

shell 'ls /tmp'

Allowing additional exit codes to pass

shell 'puppet agent -t', :acceptable_exit_codes => [0,2]

Using the returned result for any kind of checking

if shell('ls -la ~').stdout =~ /\.bin/
  ...do some action...
end

Using TestCase helpers from within a test.

agents.each do |agent|
  shell('cat /etc/puppet/puppet.conf') do |result|
    assert_match result.stdout, /server = #{master}/, 'WTF Mate'
  end
end

Parameters:

  • command (String, Command) —

    The command to execute on host.

  • block (Proc) —

    Additional actions or assertions.

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

    Options to alter execution.

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: {} —

#with_forge_stubbed_on(host, forge_host = nil, &block) ⇒ Object

This wraps the method ‘with_host_stubbed_on` and makes the stub specific to the forge alias.

forge api v1 canonical source is forge.puppetlabs.com forge api v3 canonical source is forgeapi.puppetlabs.com

Parameters:

  • host (String) —

    the host to perform the stub on

  • forge_host (String) (defaults to: nil) —

    The URL to use as the forge alias, will default to using :forge_host in the global options hash

#with_host_stubbed_on(host, ip_spec, &block) ⇒ Object

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

Examples:

Stub puppetlabs.com on the master to 127.0.0.1

with_host_stubbed_on(master, 'forgeapi.puppetlabs.com' => '127.0.0.1') do
  puppet( "module install puppetlabs-stdlib" )
end

Parameters:

  • host (Host, Array<Host>, String, Symbol) —

    One or more hosts to act upon, or a role (String or Symbol) that identifies one or more hosts.

  • 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]

  • 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.

Options Hash (conf_opts):

  • :__commandline_args__ (String) —

    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.

  • :__service_args__ (Hash) —

    A special setting of options for controlling how the puppet master service is handled. The only setting currently is :bypass_service_script, which if set true will force stopping and starting a webrick master using the start_puppet_from_source_* methods, even if it seems the host has passenger. This is needed in FOSS tests to initialize SSL.

Raises:

  • (ArgumentError)
