Testing yaml files being passed as parameters using rspec-puppet

[choffee]

I have a define which takes a yaml file as a parameter and want to check that my template creates valid yaml.

I am currently using regexp to test bits of it like so

  should contain_mydefine('foo').with_yaml_content(/---\s+-part1/m)

It would be nice to be able to do

  should contain_mydefine('foo').with_yaml_content.valid_yaml()

Is there a simple way to check this?

As an alternative, if I assign the yaml to a local available is there a way in rspec to check that value?

Thanks

You can directly access the content attribute:

content = catalogue.resource(‘mydefine', ‘foo').send(:parameters)[:content]

Then you can use default spec matchers for checking what is in local variable content.
I am unsure how to check for valid yaml.

Best,
Martin

Hi Martin,

Thanks for that. It worked a treat.

I just did some simple validation in the end.

     yaml_object = YAML.load(content)
     expect(yaml_object.length).to be > 0

I validate the content elsewhere but this is just an a basic check that it's able to parse it. I have been using regexp to validate the content up to now so I suppose I could move to using this yaml module to check that as well.
