Test as if you're in someone else's shoes
summary
Shows concrete refactors inside Intercom’s Ember codebase: replace brittle asserts on internal state and CSS classes with test visible text and avoid CSS classes, move internal checks into fast unit test session service specs, convert component checks to Ember rendering/integration/rendering tests that simulate clicks and navigation, and reserve Selenium/Cypress end-to-end runs for cross-service flows like deleting an article. Includes numbers of failing patterns (many duplicated tests, unnecessary runLoop/lifecycle hooks) and before/after code sketches showing tests that actually mimic user interactions.
