• Add test kitchen testing around data bag support

hmmm
Tests pass locally but Travis is correct since the method has 42 lines and not 38 or less as configured in .rubocop_todo.yml... and rubocop is the same version

@ranjib can you review this one last time and merge when you have a chance?

[gswallow]

Could you use strings, instead of symbols, to access node attributes in your change?

[shortdudey123]

@gswallow you should be able to yes

[gswallow]

No, I mean, this pull request doesn't work for me. I had to change L127-136 of sumo_source_provider.rb to use strings, rather than symbols, when loading an encrypted data bag.

Ah gotcha

@ranjib can you update this please :)
