Issues with Testing Angular 7 Components with RouterTestingModule and Accessing getCurrentNavigation()

I am currently facing a challenge while testing a component that utilizes routerLink in the template (handled by RouterTestingModule) and getCurrentNavigation() in the corresponding ts file to access navigation state information.

Initially, I attempted to utilize only RouterTestingModule, but encountered difficulties with mocking getCurrentNavigation().

Another approach involved using a stubbed class, which became complex as it required essentially mocking the entire Router using ts-mockito.

Below is the code snippet for reference:

I would greatly appreciate any assistance or insights on this matter!

When dealing with an instance of a class in your situation, creating a mock class allows you to utilize it like so:

providers: [
        { provide: Router, useClass: RouterStub }
      ]

To incorporate your variable, you can do the following:

providers: [
        { provide: Router, useFactory: () =>  mockRouter }
      ]
