I have used simple test case to write Rspec. but while executing i am getting the below error.


require 'spec_helper'

describe "nginx" do
 it do contain_file('/var/www/index.html').with({
      'ensure' => 'present',
      'require' => 'Package[nginx]',

On execution: I am getting the below error.

root@puppet:/etc/puppet/modules/development# rspec spec/classes/init_spec.rb --format documentation

  should contain Class[nginx] (FAILED - 1)


  1) nginx should contain Class[nginx]
     Failure/Error: should contain_class('nginx')

When doing unit testing of Puppet code with rspec, attributes of a resource will be kept separate from ordering metaparameters for a resource. Your rspec code should actually look like this:

require 'spec_helper'
describe "nginx" do
  it { contain_file('/var/www/index.html').with(
      ensure: 'present',
