INTEGRATION TESTS ARE BOGUS
summary
Argues that many slow brittle integration tests become unnecessary by using Bogus to make unit doubles realistic: verified doubles (coming in RSpec 3) fail when a stubbed method was renamed or has the wrong arity, spies/assertions check actual calls, and contract tests collect all stubs/mocks and verify the real class implements those interactions. Demonstrates replacing fragile end-to-end checks with verified doubles and Bogus contract checks, notes Minitest and RSpec support and forces clearer dependency injection so hidden mismatches surface immediately.
