50 lines of code smoke test for any Angular application

A concise guide to writing a smoke test suite for Angular applications using TestBed. It covers loading the full AppModule without modification to create near end-to-end integrated tests, including two test cases: verifying the app boots without errors and verifying navigation to a route works correctly. Also touches on handling side effects with fake services or Mock Service Worker, and suggests extending the suite to cover more routes and use cases.
