在TestBed模块中创建时，NGRX和NGXS会创建单独的Store实例吗？

import { TestBed } from '@angular/core/testing';
import { StoreModule, Store } from '@ngrx/store';

describe('MyComponent', () => {
  let store: Store<any>;

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [
        StoreModule.forRoot(reducer, initialState)
      ]
    });

    store = TestBed.inject(Store);
  });

  it('should create a separate NGRX store instance', () => {
    // Perform assertions on the store instance
  });
});

import { TestBed } from '@angular/core/testing';
import { NgxsModule, Store } from '@ngxs/store';

describe('MyComponent', () => {
  let store: Store;

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [
        NgxsModule.forRoot([AppState])
      ]
    });

    store = TestBed.inject(Store);
  });

  it('should create a separate NGXS store instance', () => {
    // Perform assertions on the store instance
  });
});
