Process user should eq ["longusername"]: usernames get truncated with a '+' at the end

[TD-4242]

Description

When testing for a username running a command if it is more than 8 characters it gets truncated as per the default ps command.

InSpec and Platform Version

inspec 0.29.0 from chefdk 0.17.17

Replication Case

describe processes('process') do
  its('users') { should eq ['longusername'] }
end

  1) Processes users should eq ["longusername"]
     Failure/Error: DEFAULT_FAILURE_NOTIFIER = lambda { |failure, _opts| raise failure }

       expected: ["longusername"]
            got: ["longuse+"]

Possible Solutions

http://askubuntu.com/questions/523673/ps-aux-for-long-charactered-usernames-shows-a-plus-sign

Current workaround

shorten test to first 7 letters and a plus(+) sign:

describe processes('process') do
  its('users') { should eq ['longuse+'] }
end

@TD-4242 Thanks for reporting. Are you aware of a solution that works without a fixed character length?

[TD-4242]

I don't, but I can dig a little further, I'm sure there is something.

[chris-rock]

That would be awesome.

[TD-4242]

ps -C <process_name> -o user=

might be the trick?

Hey Bill, can you try out the code in this PR?
#1225

Here's how you can try it out:

git clone https://github.com/alexpop/inspec
cd inspec
git checkout ag-ap/processes-user-comm
bundle install
bundle exec inspec exec ...

I'm going to merge #1225.
Bill, @Anirudh-Gupta and everyone involved with this issue. Your help is greatly appreciated!
