Lost quite some time in a rspec-puppet issue due to this error
Ultimately it was due to being on os x and setting operatingsystem fact to centos, making puppet unable to find providers for the user type.

Having similar problem here, using puppet 3.4.2 (gem-installed) under a centos docker/lxc container. It doesn't reproduce in our rpm-installed EC2 instances.

Error: Got an uncaught exception of type NoMethodError: undefined method `groups' for nil:NilClass

Joshua Partlow, I think the consensus was the the PR looks OK, but there is a missing test and the commit message needs to have a bit more information explaining what happened before, what changes, and what should now happen.

updated the PR commit msg and added a spec

Comment by Tony Vu [ 2014/04/14 ]

Verified spec_tests passed for

bundle exec rspec spec/unit/property/list_spec.rb

Was there a work-around you discovered to make it possible to continue using rspec-puppet sanely until this fix is in a publicly available Puppet release?

Comment by Carlos Sanchez [ 2014/05/02 ]

yes, mocking some methods,

Comment by Alex Harvey [ 2015/06/15 ]

For anyone else searching for a workaround for earlier versions of Puppet, you can also add a global default in spec/fixtures/manifests/site.pp:

# workaround for https://tickets.puppetlabs.com/browse/PUP-1547
if $::operatingsystem == 'CentOS' {
  User {
    provider => 'useradd',

Carlos Sanchez's work around doesn't work on some earlier versions of puppet, e.g. the 3.3.1 system I'm using.
