This PR combines most of
Spec
's global state into a newSpec::CLI
class, with the end goal of making the spec runner itself more reusable and testable. The new singleton state isSpec.cli
; eventually, onlySpec
's public class methods should delegate to this singleton, and methods within the runner shouldn't refer to it. The remaining class variables are:Spec::RootContext.@@instance
Spec::RootContext.@@current_context
Spec::RootContext.@@spec_nesting
Spec::Example.@@example_counter
Spec.@@lines_cache
Class methods of
Spec
that should have beennodoc
are marked as deprecated.
