How to mock imported objects in jest?

Question

I'm having trouble mocking an object differently in two different it blocks. Both blocks end up getting the same mock (in this case where environment: 'development').

Is there a way to do this? I am aware of mockImplementationOnce but that's for functions. Thank you for any advice or guidance!

describe('myTest', () => {
  it('should return true if environment is development', () => {


   jest.mock('@alias/config', () => {
     const config = require.requireActual('@alias/config');
    return {
      ...config,
      environment: 'development'
    }})
    expect(myTest().toEqual(true);
  });

  it('should return false if environment is not development', () => {
    
   jest.mock('@alias/config', () => {
      const config = require.requireActual('@alias/config');
    return {
      ...config,
      environment: 'production'
    }})
    expect(myTest().toEqual(false);
  });

  });
});
