Constructor Details

#initialize(config = {}) ⇒ Busser

Creates a new Busser object using the provided configuration data which will be merged with any default configuration.

Parameters:

  • config (Hash) (defaults to: {}) —

    provided driver configuration

Instance Method Details

#create_sandbox ⇒ Object

Creates a temporary directory on the local workstation into which verifier related files and directories can be copied or created. The contents of this directory will be copied over to the instance before invoking the verifier’s run command. After this method completes, it is expected that the contents of the sandbox is complete and ready for copy to the remote instance.

Note: any subclasses would be well advised to call super first when overriding this method, for example:

Examples:

overriding ‘#create_sandbox`


class MyVerifier < Kitchen::Verifier::Base
  def create_sandbox
    super
    # any further file copies, preparations, etc.
  end
end

# File 'lib/kitchen/verifier/busser.rb', line 62

def create_sandbox
  super
  prepare_helpers
  prepare_suites
end

#init_command ⇒ String

Generates a command string which will perform any data initialization or configuration required after the verifier software is installed but before the sandbox has been transferred to the instance. If no work is required, then ‘nil` will be returned.

Returns:

  • (String) —

    a command string

  prefix_command(wrap_shell_code(Util.outdent!(<<-CMD)))
    #{busser_env}

    #{cmd} suite cleanup
  CMD
end

#install_command ⇒ String

Generates a command string which will install and configure the verifier software on an instance. If no work is required, then ‘nil` will be returned.

Returns:

  • (String) —

    a command string

#run_cmd ⇒ String

Deprecated.

When backwards compatibility for old Busser methods is removed, this method will no longer be available. Use ‘#run_command` in its place.

Legacy method stub for ‘#run_cmd` which calls `#run_command`.

Returns:

  • (String) —

    command string

define_method(:run_cmd) { run_command }

#run_command ⇒ String

Generates a command string which will invoke the main verifier command on the prepared instance. If no work is required, then ‘nil` will be returned.

Returns:

  • (String) —

    a command string

#sync_cmd ⇒ Object

Deprecated.
