How to use the @ngrx/effects/testing.provideMockActions function in @ngrx/effects

TestBed.configureTestingModule({
            providers: [
                BookStoreService,
                provideMockStore({
                    selectors: [
                        {
                            selector: selectBooks,
                            value: books
                        },
                        {
                            selector: selectBook,
                            value: books[0]
                        }
                    ]
                }),
                provideMockActions(mockActions)
            ]
        });
    }));

beforeEach(() => {

        const actionSource = new ReplaySubject();

        dispatch = (action: Action) => actionSource.next(action);

        TestBed.configureTestingModule({
            imports: [],
            providers: [
                provideMockActions(actionSource),
                ExecutorOutputParser
            ]
        });

        service = TestBed.get(ExecutorOutputParser);
    });
