AssertTrue (isDecoupled("my tests"))

" summary

Code-level claim: decoupled tests cut maintenance by shifting most checks down from brittle browser flows to stable integration/service layers. Uses Selenium-born UI tests refactored into a page object pattern and a DSL layer, then into direct service-layer calls behind a hexagonal/service interface with test doubles like an email gateway spy. Fixes flaky DB seeding by replacing raw YAML inserts with factories—object mother and test builder—so only a few end-to-end UI wires remain.
