Request for mocks for unit-tests

🚀 Feature request

Could we get mocks like how you've provided it in your universal package? Ref - link

import '@ng-web-apis/universal/mocks';

Hey 👋 You mean like for testing with jest? I believe you can already just use mocks from universal, as well as tokens from it. Please let me know if that works for you.

[batbrain9392]

For Jasmine/Karma. But will check with the mocks from universal.

But the mocks and tokens can be taken from universal, why maintain 2 repos with the same functionalities?

[waterplea]

This library is just a library of token so you make your apps without any direct access to global entities, because they might not be available in some environments. Universal package is the package of substitutes for those tokens for server side which also might work in other environments where they are missing. For example jest testing is a lot like universal as it is also emulated DOM. Is Jasmine/Karma you don't need mocks, because tokens are available as is. But you can easily mock them with spies etc. in unit tests.

@waterplea Do you have an example of how these tokens can be mocked in Jasmine/Karma unit tests?

[waterplea]

When you configure TestBed you can add to providers something like this:

{
  provide: WINDOW,
  useValue: { 
    matchMedia(query: string): boolean {
      return query === '(min-width: 400px)';
    }
  }
}

for example, if your code depends on screen size by running window.matchMedia and you want to test particular configuration
