嘲笑对相同对象的测试

Question

我的一个单元测试失败，输出如下所示

 expect(jest.fn()).toHaveBeenCalledWith(...expected)

- Expected
+ Received

- {"cartId": "_id_", "devices": [{"foo": "bar"}], "language": "_language_", "province": "_province_"},
+ {"cartId": "_id_", "devices": [{"foo": "bar"}], "language": "_language_", "province": "_province_"},

行

 expect(mockTransformer).toHaveBeenCalledWith({...

问题是，如果期望和接收的结果相同，该测试如何失败？

这是图中的测试代码：

   expect(mytestingfunction).toHaveBeenCalledWith({
      devices: [{ foo: 'bar' }],
      cartId: '_id_',
      language: '_language_',
      province: '_province_'
    })
