        Error: Type AppComponent is part of the declarations of 2 modules: AppModule and DynamicTestModule! Please consider moving AppComponent to a higher module that imports AppModule and DynamicTestModule. You can also create a new NgModule that exports and includes AppComponent then import that NgModule in AppModule and DynamicTestModule.

После этих ошибок я изменил свой TestBed в app.component.spec.ts и добавил 

schemas: [CUSTOM_ELEMENTS_SCHEMA]

Но это такжетакой же. Я пытаюсь протестировать угловое приложение в первый раз, и я немного запутался. Увидел этот вопрос: Элемент не известен ошибка в Карме при запуске "тест NG"

Также мое приложение работает нормально, оно подключается к бэкэнду и все основные функции были выполнены. Любая помощь будет принята с благодарностью.

решено: Спасибо, ребята, за помощь, пользователь Pace помог мне. Когда я создавал свои компоненты, я всегда удалял файлы spec.ts, потому что они нужны мне для выполнения модульного тестирования сервисов и фильтрации каналов, но была допущена одна ошибка :). В начале создания приложения с использованием углового клика я не удалял app.component.spec.ts, поэтому эти ошибки имеют смысл, поскольку этот компонент хотел загрузить все остальные компоненты для целей тестирования, но не смог найти их тестовые файлы. Я большой новичок в Angular, и мне становится немного страшно, когда я вижу такие большие ошибки, хаха :))
