Answer 1

Angular 文档说 您应该为管道和服务编写独立的单元测试。 独立的单元测试不需要 Testbed。 ( https://angular.io/guide/testing#isolated-unit-tests )
对于 Angular Components 测试，您很可能希望使用 Testbed，我仍将其视为单元测试。现在说到这里，我应该再次引用文档

Good developers write both kinds of tests for the same application part, often in the same spec file. Write simple isolated unit tests to validate the part in isolation. Write Angular tests to validate the part as it interacts with Angular, updates the DOM, and collaborates with the rest of the application.

希望对您有所帮助。
