RSpec: It's Not Actually Magic
summary
Shows RSpec source step by step so the DSL stops feeling magical: how describe/it/expect/eq map to example groups, expectation targets and matchers, how blocks run via module_exec and class_exec, how implicit predicates and the implicit matcher work, and how mocks install method double proxies into an object’s singleton class to capture calls and verify expectations during teardown. Includes the emoji-as-syntax demo and concrete code paths so the mechanics and tradeoffs are clear.
