Module: Kettle::Dev::ExitAdapter

Defined in:
lib/kettle/dev/exit_adapter.rb,
sig/kettle/dev.rbs

Overview

Exit/abort indirection layer to allow controllable behavior in tests.

Production/default behavior delegates to Kernel.abort / Kernel.exit, which raise SystemExit. Specs can stub these methods to avoid terminating the process or to assert on arguments without coupling to Kernel.

Example (RSpec):

allow(Kettle::Dev::ExitAdapter).to receive(:abort).and_raise(SystemExit.new(1))

This adapter mirrors the "mockable adapter" approach used for GitAdapter.
