Adam,
 
So you have come across it too!

Grrrr!

I will try your suggestion.

Thanks!

So, you're going to hate this, but it's true. Right now, because of the way Chef loads things under the hood, ChefSpec appears to not be able to mock class methods at all. Instead, try mocking with any_instance_of, and see how that works for you.

Hi Brandon,

This is so frustrating.

I've been trying all afternoon to successfully stub the Chef::EncryptedDataBagItem.load method without success!

This is my test file:

describe 'core::local_users_linux' do 

let(:chef_run) do
ChefSpec::SoloRunner.new do |node|
node.set['core']['userlist'] = 'angela'
end.converge(described_recipe)
end 

before do
allow(Chef::EncryptedDataBagItem).to receive(:load).and_return({
                "id" => "angela",
                "password" => "London2014"
})
end  
context 'linux' do

      it 'stubbed databag does not raise error' do

     expect(chef_run).to_not raise_error
      end
end

end

When I test this file, I get the following error:-
F

Failures:

  1) core::local_users_linux linux stubbed databag does not raise error
     Failure/Error: expect(chef_run).to_not raise_error

Should it be trying to run the load method in my recipe?. Shouldn't that be stubbed and shouldn't the test be returning my canned hash?

Please help!

Angela,

You'll need to stub the data bag calls for each of the users, or better yet, if that list of users is being provided through attributes, stub that attribute with a mock list of user(s). Something like this:

runner.node.set['my']['userlist'] = ['foo']


You can quickly test this is the issue by adding the following into your before block. 

allow(Chef::EncryptedDataBagItem).to receive(:load).and_return({})

This will stub the load method regardless of the parameters passed to the load method, and will return an empty hash, which you can update to your liking.


Thanks,

Brandon

Hi Brandon,

Yes.

In the main recipe, it iterates through the userlist and decrypts each encrypted data bag.

What I would like to do is to stub the code that performs the decryption (have refactored my code so have put the decryption into a method) so essentially pass it a canned encrypted data bag and have it spit out a canned id and password. This will ensure that this error Failed to read the private key C:\chef\client.pem: #<Errno::ENOENT: No such file or directory - C:\chef\client.pem> doens't arise as the method that calls the decryption will be stubbed.

Hope that helps.

Thanks

Angela, Are you loading more than one encrypted data bag item in that recipe? From the backtrace, it looks like you might be iterating through a list of users.

Still getting the same error which means the stub isn't working.

thanks anyway

Quoting the README of ChefSpec on this subject: (https://github.com/sethvargo/chefspec#data-bag--data-bag-item)

If you are using Encrypted Data Bag Items, you'll need to dive into the RSpec layer and stub that class method instead:

describe 'example::default' do
  before do
    allow(Chef::EncryptedDataBagItem).to receive(:load).with('users', 'svargo').and_return(...)
  end
end

Seems it had to be done in the before block.
Another entry of how to: https://github.com/sethvargo/chefspec/issues/249

Hope this helps

Hello everyone,
 
Does anyone here use ChefSpec regularly? If so, please help!
 
I've got a situation where I have encrypted databags which I decrypt to find the passwords for users (in my local_users recipe). I have generated an encrypted_data_bag_secret that I use with my Chef Solo.
 
This is my spec file:
 
#local_users_spec.rb
 
require 'spec_helper'
 
describe 'core::local_users' do 
 
let(:chef_run) { ChefSpec::SoloRunner.new.converge(described_recipe)}
    
context 'windows' do
let(:chef_run) do
runner = ChefSpec::SoloRunner.new(
 
'platform' => 'windows',
'version' => '2012'
)
runner.node.set['core']['install_flavor'] = 'windows'
runner.converge('core::local_users')
      end
 
      it 'stubbed databag does not raise error' do
     plain_pass = "London2014"
 
 
allow(Chef::EncryptedDataBagItem).to receive(:load).with("aws-admin-passwords", "svc_goagent")["password"].and_return(plain_pass)
     expect(chef_run).to_not raise_error
      end
end
end
 
When I run this, I get the following:-
 
C:\git\cookbook-core>rspec spec/local_users_spec.rb
ffi-yajl/json_gem is deprecated, these monkeypatches will be dropped shortly
[2015-03-16T12:24:31+00:00] WARN: Failed to read the private key C:\chef\client.pem: #<Errno::ENOENT: No such file or directory - C:\chef\client.pem>

        from C:/git/cookbook-core/spec/local_users_spec.rb:1:in `<top (required)>'
       ...
 
I expect the test to pass and not generate an error. However I receive an error which indicates the test is not stubbing my encrypted data bag (especially the No such file or directory - C:\chef\client.pem> errror). Can anyone help me with this?
 
Thanks
