Add the pick() function This function is similar to a coalesce function in SQL in that it will return the first value in a list of values that is not undefined or an empty string (two things in Puppet that will return a boolean false value). Typically, this function is used to check for a value in the Puppet Dashboard/Enterprise Console, and failover to a default value like the following: $real_jenkins_version = pick($::jenkins_version, '1.449') The value of $real_jenkins_version will first look for a top-scope variable called 'jenkins_version' (note that parameters set in the Puppet Dashboard/ Enterprise Console are brought into Puppet as top-scope variables), and, failing that, will use a default value of 1.449.

require 'spec_helper'
Convert tests to use plain rspec-puppet Tests in the new style produces the following documentation output: abs should not eq nil should run abs() and raise an Puppet::ParseError should run abs(-34) and return 34 should run abs("-34") and return 34 should run abs(34) and return 34 should run abs("34") and return 34
