hiera-mock

Hiera backend to return data from a single yaml file or random data (meant for testing purposes)

Example

Content of hiera.yaml and testdata.yaml are in ./example

Results:

Strings:

$ hiera -c hiera.yaml mykey
abc

$ hiera -c hiera.yaml mykeyX
mocked-6IpG7AS502qmg9W

$ hiera -c hiera.yaml mykeyX
mocked-Ur3jfD9As5cgYV8W

Arrays:

$ hiera -a -c hiera.yaml myarray
["item1", "item2"]

$ hiera -a -c hiera.yaml myarrayX
["mocked-l07OFvt29ciL",
 "mocked-hKE3ftukpFjQUl",

 "mocked-XO0ijv9kbJG"]

$ hiera -a -c hiera.yaml myarrayX
["mocked-rZAM01", "mocked-wu1SV5TNjaKepmX7", "mocked-zn2qSOGxQBvb"]

Hashes:

$ hiera -h -c hiera.yaml myhash
{"x"=>5, "y"=>3}

$ hiera -h -c hiera.yaml myhashX

Nil:

$ hiera -c hiera.yaml mynil
nil

$ hiera -c hiera.yaml -a mynil
nil

$ hiera -c hiera.yaml -h mynil
nil

$ hiera -c hiera.yaml mynilX

Returning nil will first go to the next hiera layer, and finally (if nothing else returns something) make the hiera function use the default value. If no default was defined in the function call, it will throw an error. Using ~ in hiera-mock will make such situations visible.
