Answer 1

For scenarios in which you are reading the query params from the ActivatedRouteSnapshot like:

this.someProperty = this.route.snapshot.data.query['paramKey'];

The below code will be helpful in tests for feeding query params data into the route

{ 
  provide: ActivatedRoute, 
  useValue: {
    snapshot: {
      data: {
        query: {
          paramKey: 'paramValue'
        }
      }
    }
  }
}
