Dispatched an NgRx action and nothing happened? A fixed diagnostic order isolates the five real causes: registration scope, action mismatches, dead effect streams, wrong flattening operators, and missing reducer handling.
How to configure NgRx Effects with proper error handling, operator selection, and module registration to avoid silent failures in Angular apps.
Goal is to validate an NgRx Effect integration without importing production credentials, environment files, or real network endpoints. The effect is the boundary between intent actions and a gateway service, and tests should assert the observable contract of success and failure actions using a mocked Actions stream and an overridden API configuration token.
