As far as I know, the only reason you would use params.pp is if you have
sane defaults you want to pass to variables. When you do, you use:
class test inherits test::params {
}
for your init.pp. You don't use an include statement as far as I know.
However, because you aren't defining sane defaults, you don't need the
params.pp.
Instead just make your test/manifests/init.pp look like:
class test {
$p1 = hiera('param1')
$p2 = hiera('param2')
file { 'testfile' :
path => "/tmp/testfile",
content => template("test/testfile.erb"),
}
}
Hope that helps.
