How do you unit test store.select in component's method?

[sameerthekhans]

//Todos component
subscribeTodos() {
  this.store
    .select(GetTodos)
    .subscribe(todos => {
      this.todos = todos;
    });
}

My requirement is

//Todos Spec
it('should get todos',() => {
  const expectation = {title: 'Example Todo'};
  jest.spyOn(store, 'select').mockReturnValue(of(expectation));

  component.subscribeTodos(); //I will invoke this 

  expect(component.todos).toBe(expectation); //and want to validate the todos property
})
