AssertTrue (isDecoupled(“my tests”))
summary
Argues that loose coupling cuts test maintenance: a quiz app change repeatedly breaks hundreds of UI-driven Selenium tests, tests sit skipped for months, and full suite runs take 30–40 minutes. Fix is layered testing: page objects and a DSL layer to shield UI churn, shift business checks to a service layer with adapters so external services become swappable, use email gateway spy storing messages and other test doubles to assert behavior, and create fixtures via object mother/test builders and in-memory repositories — this reduces failures and cuts runtime to seconds.
