Class Method Details

.initialize_via_fallback_compatibility(config) ⇒ Object

This method is for initializing puppet state for testing for older versions of puppet that do not support the new TestHelper API. As you can see, this involves explicitly modifying global variables, directly manipulating Puppet’s Settings singleton object, and other fun implementation details that code external to puppet should really never know about.

.initialize_via_testhelper(config) ⇒ Object

This method uses the “new”/preferred approach of delegating all of the test state initialization to puppet itself, via Puppet::Test::TestHelper API. This should be fairly future-proof as long as that API doesn’t change, which it hopefully will not need to.
