What is the method for mocking ofActionSuccessful in ngxs?

edit

To mock ofActionSuccessful in ngxs, you can use the spyOn operator provided by Jasmine testing framework. This will allow you to spy on the ofActionSuccessful function and provide a mock implementation that you can use in your tests.

Here is an example:

import { of } from 'rxjs';
import { spyOn } from 'jasmine';
import { Store } from '@ngxs/store';
import { ofActionSuccessful } from '@ngxs/store/operators';

describe('Test ofActionSuccessful operator', () => {
  let store: Store;

  beforeEach(() => {
    store = new Store();
  });

  it('should mock ofActionSuccessful', async () => {
    spyOn(store, 'dispatch').and.returnValue(of(true)); // Mock store.dispatch to return an observable of true

    let result: any;
    await store.dispatch(new MyAction()).pipe(
      ofActionSuccessful(MySuccessAction),
    ).toPromise().then((res) => result = res); // Trigger the action and use ofActionSuccessful operator

    expect(result).toEqual(new MySuccessAction()); // Assert that the result is the expected success action
  });
});
